113-417: A one-party state , single-party state , one-party system or single-party system is a governance structure in which only a single political party controls the ruling system. In a one-party state, all opposition parties are either outlawed or enjoy limited and controlled participation in elections . The term " de facto one-party state" is sometimes used to describe a dominant-party system that, unlike
226-556: A liberal - conservative divide, or around religious disputes. The spread of the party model of politics was accelerated by the 1848 Revolutions around Europe. The strength of political parties in the United States waned during the Era of Good Feelings , but shifted and strengthened again by the second half of the 19th century. This was not the only country in which the strength of political parties had substantially increased by
339-456: A party chair , who may be different people from the party leader. These executive organizations may serve to constrain the party leader, especially if that leader is an autocrat. It is common for political parties to conduct major leadership decisions, like selecting a party executive and setting their policy goals, during regular party conferences . Much as party leaders who are not in power are usually at least nominally competing to become
452-463: A single-member district electoral system tend to have very few parties, whereas countries that use proportional representation tend to have more. The number of parties in a country can also be accurately estimated based on the magnitude of a country's electoral districts and the number of seats in its legislature. An informative way to classify the party systems of the world is by how many parties they include. Because some party systems include
565-416: A candidate in one electoral district has an incentive to assist a similar candidate in a different district. Thus, political parties can be mechanisms for preventing candidates with similar goals from acting to each other's detriment when campaigning or governing. This might help explain the ubiquity of parties: if a group of candidates form a party and are harming each other less, they may perform better over
678-543: A candidate to victory in an election. Some scholars argue that the first modern political parties developed in early modern Britain in the 17th century, after the Exclusion Crisis and the Glorious Revolution . The Whig faction originally organized itself around support for Protestant constitutional monarchy as opposed to absolute rule , whereas the conservative Tory faction (originally
791-403: A community of party members. Parties in democracies usually select their party leadership in ways that are more open and competitive than parties in autocracies, where the selection of a new party leader is likely to be tightly controlled. In countries with large sub-national regions, particularly federalist countries, there may be regional party leaders and regional party members in addition to
904-532: A country with multiple competitive parties is not necessarily democratic, and the politics of many autocratic countries are organized around one dominant political party. The ubiquity and strength of political parties in nearly every modern country has led researchers to remark that the existence of political parties is almost a law of politics, and to ask why parties appear to be such an essential part of modern states. Political scientists have therefore come up with several explanations for why political parties are
1017-609: A deeper connection to the electorate. The idea of people forming large groups or factions to advocate for their shared interests is ancient. Plato mentions the political factions of Classical Athens in the Republic , and Aristotle discusses the tendency of different types of government to produce factions in the Politics . Certain ancient disputes were also factional, like the Nika riots between two chariot racing factions at
1130-413: A democracy will often affiliate with a specific political party. Party membership may include paying dues, an agreement not to affiliate with multiple parties at the same time, and sometimes a statement of agreement with the party's policies and platform. In democratic countries, members of political parties often are allowed to participate in elections to choose the party leadership. Party members may form
1243-456: A democracy. There have been periods of government exclusively or entirely by one party in some countries that are often considered to have been democratic, and which had no official legal barriers to the inclusion of other parties in the government; this includes recent periods in Botswana , Japan , Mexico , Senegal , and South Africa . It can also occur that one political party dominates

#17327839308941356-485: A host of political systems and situations. Other approaches include the study of equation-based models and opinion dynamics. Political theorists approach theories of political phenomena with a similar diversity of positions and tools, including feminist political theory , historical analysis associated with the Cambridge school , and Straussian approaches . Political science may overlap with topics of study that are
1469-487: A key role in setting up political science departments that were distinct from history, philosophy, law, sociology, and economics. The journal Political Science Quarterly was established in 1886 by the Academy of Political Science. In the inaugural issue of Political Science Quarterly , Munroe Smith defined political science as "the science of the state. Taken in this sense, it includes the organization and functions of
1582-426: A large membership base. Further, mass parties prioritize the mobilization of voters and are more centralized than elite parties. The term "catch-all party" was developed by German-American political scientist Otto Kirchheimer to describe the parties that developed in the 1950s and 1960s as a result of changes within the mass parties. The term "big tent party" may be used interchangeably. Kirchheimer characterized
1695-485: A large number of parties that have a very low probability of winning elections, it is often useful to think about the effective number of parties (the number of parties weighted by the strength of those parties) rather than the literal number of registered parties. In a non-partisan system, no political parties exist, or political parties are not a major part of the political system. There are very few countries without political parties . In some non-partisan countries,
1808-401: A large number of political parties around the world, not all political parties have an organizing ideology, or exist to promote ideological policies. For example, some political parties may be clientelistic or patronage -based organizations, which are largely concerned with distributing goods. Other political parties may be created as tools for the advancement of an individual politician. It
1921-524: A local official is performing poorly in the eyes of the residents. This gives locals the opportunity to monitor local officials and communicate satisfaction with the local government. Throughout the country, members of the one party hold key political positions. In doing so, the party avoids committing outright fraud and rather sustains their power at the local level with strategic appointment of elites. Data on one-party regimes can be difficult to gather given their lack of transparency. As of 2024,
2034-550: A lower rate than dominant-party dictatorships. While one-party states prohibit opposition parties, some allow for elections at the smallest local level. One-party states lack any legitimate competition. Therefore, they place elites and sympathetic candidates in key administrative races. For example, the Chinese Communist Party exercises political control by infiltrating village administrations. They view these positions as crucial for gathering information on
2147-495: A major upheaval in their politics and have not yet returned to a stable system of political parties. For example, the United States began as a non-partisan democracy, and it evolved a stable system of political parties over the course of many decades. A country's party system may also dissolve and take time to re-form, leaving a period of minimal or no party system, such as in Peru following the regime of Alberto Fujimori . However, it
2260-558: A more analytical corpus of knowledge in the discipline. This period saw a surge of research that borrowed theory and methods from economics to study political institutions, such as the United States Congress, as well as political behavior, such as voting. William H. Riker and his colleagues and students at the University of Rochester were the main proponents of this shift. Despite considerable research progress in
2373-399: A nearly universal political phenomenon. One of the core explanations for the existence of political parties is that they arise from pre-existing divisions among people: society is divided in a certain way, and a party is formed to organize that division into the electoral competition. By the 1950s, economists and political scientists had shown that party organizations could take advantage of
SECTION 20
#17327839308942486-511: A number of countries, particularly longstanding European democracies. Political scientists have distinguished between different types of political parties that have evolved throughout history. These include elite parties, mass parties, catch-all parties and cartel parties. Elite parties were political elites that were concerned with contesting elections and restricted the influence of outsiders, who were only required to assist in election campaigns. Mass parties tried to recruit new members who were
2599-626: A one-party state, allows (at least nominally) multiparty elections, but the existing practices or balance of political power effectively prevent the opposition from winning power. Membership in the ruling party tends to be relatively small compared to the population. With such a small winning coalition, leaders in one-party states usually lack the incentive to care about the well-being of citizens. Rather, they give out private goods to fellow elites to ensure continued support. One-party, compared to dominant-party dictatorships, structure themselves unlike democracies. They also turn into democracies at
2712-422: A particular country's elections . It is common for the members of a party to hold similar ideas about politics , and parties may promote specific ideological or policy goals. Political parties have become a major part of the politics of almost every country, as modern party organizations developed and spread around the world over the last few centuries. Although some countries have no political parties , this
2825-417: A phenonmenon observable among European Green parties during their transformation from radical environmentalist movements to mainstream centre-left parties. An Entrepreneurial party is a political party that is centered on a political entrepreneur , and dedicated to the advancement of that person or their policies. While some definitions of political parties state that a party is an organization that advances
2938-886: A realistic chance of competing to form government. One current example of a two-party system is the United States , where the national government has for much of the country's history exclusively been controlled by either the Democratic Party or the Republican Party . Other examples of countries which have had long periods of two-party dominance include Colombia , Uruguay , Malta , and Ghana . Two-party systems are not limited to democracies; they may be present in authoritarian regimes as well. Competition between two parties has occurred in historical autocratic regimes in countries including Brazil and Venezuela . A democracy's political institutions can shape
3051-547: A rich field for the growth of both normative and positive political science, with each part of the discipline sharing some historical predecessors. The American Political Science Association and the American Political Science Review were founded in 1903 and 1906, respectively, in an effort to distinguish the study of politics from economics and other social phenomena. APSA membership rose from 204 in 1904 to 1,462 in 1915. APSA members played
3164-446: A separate constituent college or academic department, then political science may be a separate department housed as part of a division or school of humanities or liberal arts . At some universities, especially research universities and in particular those that have a strong cooperation between research, undergraduate, and graduate faculty with a stronger more applied emphasis in public administration, political science would be taught by
3277-412: A single best policy choice without some institution constraining their options. Another prominent explanation for why political parties exist is psychological: parties may be necessary for many individuals to participate in politics because they provide a massively simplifying heuristic , which allows people to make informed choices with much less mental effort than if voters had to consciously evaluate
3390-558: A smaller group can be a feature of party leadership transitions in more autocratic countries, where the existence of political parties may be severely constrained to only one legal political party, or only one competitive party. Some of these parties, like the Chinese Communist Party , have rigid methods for selecting the next party leader, which involves selection by other party members. A small number of single-party states have hereditary succession, where party leadership
3503-405: A source of party income and were often expected to spread party ideology as well as assist in elections. In the United States, where both major parties were elite parties, the introduction of primaries and other reforms has transformed them so that power is held by activists who compete over influence and nomination of candidates. An elite party is a type of political party that was dominant in
One-party state - Misplaced Pages Continue
3616-479: A specific set of ideological or policy goals, many political parties are not primarily motivated by ideology or policy, and instead exist to advance the career of a specific political entrepreneur . Political ideologies are one of the major organizing features of political parties, and parties often officially align themselves with specific ideologies. Parties adopt ideologies for a number of reasons. Ideological affiliations for political parties send signals about
3729-413: A study of human behavior , in all aspects of politics , observations in controlled environments are often challenging to reproduce or duplicate, though experimental methods are increasingly common (see experimental political science ). Citing this difficulty, former American Political Science Association President Lawrence Lowell once said "We are limited by the impossibility of experiment. Politics
3842-465: A sub-national region of a democratic country that has a competitive national party system; one example is the southern United States during much of the 19th and 20th centuries, where the Democratic Party had almost complete control, with the Southern states being functionally one-party regimes, though opposition parties were never prohibited. In several countries, there are only two parties that have
3955-411: A university discipline was marked by the creation of university departments and chairs with the title of political science arising in the late 19th century. The designation "political scientist" is commonly used to denote someone with a doctorate or master's degree in the field. Integrating political studies of the past into a unified discipline is ongoing, and the history of political science has provided
4068-416: A variety of capacities, people educated and trained in political science can add value and expertise to corporations . Private enterprises such as think tanks , research institutes, polling and public relations firms often employ political scientists. Political scientists may study political phenomena within one specific country. For example, they may study just the politics of the United States or just
4181-476: A very large portion of society and it can play substantial roles in civil society that are not necessarily directly related to political governance; one example of this is the Chinese Communist Party . Bans on competing parties can also ensure that only one party can ever realistically hold power, even without completely outlawing all other political parties. For example, in North Korea , more than one party
4294-628: A way that does not conform to the dominant economic left-right divide in politics, in turn emphasising issues that do not attain prominence within the other parties. Further, niche parties do not respond to changes in public opinion to the extent that mainstream parties do. Examples of niche parties include Green parties and extreme nationalist parties, such as the National Rally in France. However, over time these parties may grow in size and shed some of their niche qualities as they become larger,
4407-412: Is methodologically diverse and appropriates many methods originating in psychology, social research , political philosophy, and many others, in addition to those that developed chiefly within the field of political science. Political scientists approach the study of politics from a host of different ontological orientations and with a variety of different tools. Because political science is essentially
4520-416: Is a defining feature of contemporary political science. Empirical political science methods include the use of field experiments, surveys and survey experiments, case studies, process tracing, historical and institutional analysis, ethnography, participant observation, and interview research. Political scientists also use and develop theoretical tools like game theory and agent-based models to study
4633-401: Is a social science dealing with systems of governance and power, and the analysis of political activities, political institutions, political thought and behavior, and associated constitutions and laws . As a social science, contemporary political science started to take shape in the latter half of the 19th century and began to separate itself from political philosophy and history. Into

4746-951: Is a social study concerning the allocation and transfer of power in decision making , the roles and systems of governance including governments and international organizations , political behaviour, and public policies . It measures the success of governance and specific policies by examining many factors, including stability , justice , material wealth , peace , and public health . Some political scientists seek to advance positive theses (which attempt to describe how things are, as opposed to how they should be) by analysing politics; others advance normative theses, such as by making specific policy recommendations. The study of politics and policies can be closely connected—for example, in comparative analyses of which types of political institutions tend to produce certain types of policies. Political science provides analysis and predictions about political and governmental issues. Political scientists examine
4859-521: Is also common, in countries with important social cleavages along ethnic or racial lines, to represent the interests of one ethnic group or another. This may involve a non-ideological attachment to the interests of that group, or may be a commitment based on an ideology like identity politics . While any of these types of parties may be ideological, there are political parties that do not have any organizing ideology. Political parties are ubiquitous across both democratic and autocratic countries, and there
4972-423: Is also possible – albeit rare – for countries with no bans on political parties, and which have not experienced a major disruption, to nevertheless have no political parties: there are a small number of pacific island democracies, such as Palau , where political parties are permitted to exist and yet parties are not an important part of national politics. In a one-party system , power
5085-409: Is an observational, not an experimental science." Because of this, political scientists have historically observed political elites, institutions, and individual or group behaviour in order to identify patterns, draw generalizations, and build theories of politics. Like all social sciences, political science faces the difficulty of observing human actors that can only be partially observed and who have
5198-510: Is common for democratic elections to feature competitions between liberal , conservative , and socialist parties; other common ideologies of very large political parties include communism , populism , nationalism , and Islamism . Political parties in different countries will often adopt similar colours and symbols to identify themselves with a particular ideology. However, many political parties have no ideological affiliation, and may instead be primarily engaged in patronage , clientelism ,
5311-486: Is extremely rare. Most countries have several parties while others only have one . Parties are important in the politics of autocracies as well as democracies , though usually democracies have more political parties than autocracies. Autocracies often have a single party that governs the country, and some political scientists consider competition between two or more parties to be an essential part of democracy. Parties can develop from existing divisions in society, like
5424-576: Is held entirely by one political party. When only one political party exists, it may be the result of a ban on the formation of any competing political parties, which is a common feature in authoritarian states. For example, the Communist Party of Cuba is the only permitted political party in Cuba , and is the only party that can hold seats in the legislature. When only one powerful party is legally permitted to exist, its membership can grow to contain
5537-407: Is inherited by the child of an outgoing party leader. Autocratic parties use more restrictive selection methods to avoid having major shifts in the regime as a result of successions. In both democratic and non-democratic countries, the party leader is often the foremost member of a larger party leadership. A party executive will commonly include administrative positions, like a party secretary and
5650-408: Is largely insignificant as parties use the resources of the state to maintain their position within the political system. Niche parties are a type of political party that developed on the basis of the emergence of new cleavages and issues in politics, such as immigration and the environment. In contrast to mainstream or catch-all parties, niche parties articulate an often limited set of interests in
5763-526: Is officially permitted to exist and even to seat members in the legislature, but laws ensure that the Workers' Party of Korea retains control. It is also possible for countries with free elections to have only one party that holds power. These cases are sometimes called dominant-party systems or particracies . Scholars have debated whether or not a country that has never experienced a transfer of power from one party to another can nevertheless be considered
SECTION 50
#17327839308945876-399: Is often very little change in which political parties have a chance of holding power in a country from one election to the next. This makes it possible to think about the political parties in a country as collectively forming one of the country's central political institutions , called a party system. Some basic features of a party system are the number of parties and what sorts of parties are
5989-442: Is reduced as catch-all parties are financed in part by the state or by donations. In Europe, the shift of Christian Democratic parties that were organized around religion into broader centre-right parties epitomizes this type. Cartel parties are a type of political party that emerged post-1970s and are characterized by heavy state financing and the diminished role of ideology as an organizing principle. The cartel party thesis
6102-432: Is the ideology that is most closely connected to the history of democracies and is often considered to be the dominant or default ideology of governing parties in much of the contemporary world. Many of the traditional competitors to liberal parties are conservative parties. Socialist, communist, feminist, anarchist, fascist, and nationalist parties are more recent developments, largely entering political competitions only in
6215-648: The Federalist Party and the Democratic-Republican Party . By the early 19th century, a number of countries had developed stable modern party systems. The party system that developed in Sweden has been called the world's first party system, on the basis that previous party systems were not fully stable or institutionalized. In many European countries, including Belgium, Switzerland, Germany, and France, political parties organized around

A few instances of recorded political groups or factions in history included the late Roman Republic's Populares and Optimates factions as well as the Dutch Republic's Orangists and the Staatsgezinde . However, modern political parties are considered to have emerged around the end of the 18th century; they are usually considered to have first appeared in Europe and

At the end of

Political scientists look at a variety of data, including constitutions, elections , public opinion , and public policy , foreign policy , legislatures, and judiciaries. Political scientists will often focus on the politics of their own country; for example, a political scientist from Indonesia may become an expert in the politics of Indonesia. The theory of political transitions, and

Parties can sometimes be organized according to their ideology using an economic left–right political spectrum . However, a simple left-right economic axis does not fully capture the variation in party ideologies. Other common axes that are used to compare

While political science implies the use of the scientific method , political studies implies a broader approach, although the naming of degree courses does not necessarily reflect their content. Separate, specialized or, in some cases, professional degree programs in international relations , public policy , and public administration are common at both

Political parties are collective entities and activities that organize competitions for political offices. The members of a political party contest elections under a shared label. In a narrow definition, a political party can be thought of as just
7232-405: The base of the volunteer activists and donors who support political parties during campaigns. The extent of participation in party organizations can be affected by a country's political institutions, with certain electoral systems and party systems encouraging higher party membership. Since at least the 1980s, membership in large traditional party organizations has been steadily declining across

Despite the complexities, contemporary political science has progressed by adopting a variety of methods and theoretical approaches to understanding politics, and methodological pluralism

Although the framers of the 1787 United States Constitution did not all anticipate that American political disputes would be primarily organized around political parties, political controversies in the early 1790s over the extent of federal government powers saw the emergence of two proto-political parties :

Generally, classical political philosophy is primarily defined by a concern for Hellenic and Enlightenment thought, political scientists are also marked by a great concern for " modernity " and the contemporary nation state , along with the study of classical thought, and as such share more terminology with sociologists (e.g., structure and agency ). The advent of political science as
7684-438: The claim that parties emerge from existing cleavages, or arguing that the claim is not empirically testable. Others note that while social cleavages might cause political parties to exist, this obscures the opposite effect: that political parties also cause changes in the underlying social cleavages. A further objection is that, if the explanation for where parties come from is that they emerge from existing social cleavages, then
7797-424: The cognitive burden for people to cast informed votes. However, some evidence suggests that over the last several decades, the strength of party identification has been weakening, so this may be a less important function for parties to provide than it was in the past. Political parties are often structured in similar ways across countries. They typically feature a single party leader, a group of party executives, and
7910-544: The discipline based on all types of scholarship discussed above, scholars have noted that progress toward systematic theory has been modest and uneven. In 2000, the Perestroika Movement in political science was introduced as a reaction against what supporters of the movement called the mathematicization of political science. Those who identified with the movement argued for a plurality of methodologies and approaches in political science and for more relevance of
8023-500: The discipline to those outside of it. Some evolutionary psychology theories argue that humans have evolved a highly developed set of psychological mechanisms for dealing with politics. However, these mechanisms evolved for dealing with the small group politics that characterized the ancestral environment and not the much larger political structures in today's world. This is argued to explain many important features and systematic cognitive biases of current politics. Political science
8136-470: The discipline. A focus on studying political behavior, rather than institutions or interpretation of legal texts, characterized early behavioral political science, including work by Robert Dahl , Philip Converse , and in the collaboration between sociologist Paul Lazarsfeld and public opinion scholar Bernard Berelson . The late 1960s and early 1970s witnessed a takeoff in the use of deductive, game-theoretic formal modelling techniques aimed at generating
8249-575: The distribution of voters' preferences over political issues, adjusting themselves in response to what voters believe in order to become more competitive. Beginning in the 1960s, academics began identifying the social cleavages in different countries that might have given rise to specific parties, such as religious cleavages in specific countries that may have produced religious parties there. The theory that parties are produced by social cleavages has drawn several criticisms. Some authors have challenged it on empirical grounds, either finding no evidence for
8362-413: The divisions between lower and upper classes , and they streamline the process of making political decisions by encouraging their members to cooperate. Political parties usually include a party leader, who has primary responsibility for the activities of the party; party executives, who may select the leader and who perform administrative and organizational tasks; and party members, who may volunteer to help
8475-494: The end of the century; for example, around this time the Irish political leader Charles Stewart Parnell implemented several methods and structures like party discipline that would come to be associated with strong grassroots political parties. At the beginning of the 20th century in Europe, the liberal–conservative divide that characterized most party systems was disrupted by the emergence of socialist parties, which attracted
8588-411: The entire party, and some voters decide how to vote in elections partly based on how much they like the leaders of the different parties. The number of people involved in choosing party leaders varies widely across parties and across countries. On one extreme, party leaders might be selected from the entire electorate; on the opposite extreme, they might be selected by just one individual. Selection by
8701-418: The fact that a party is focused on electing candidates, whereas a parliamentary group is a group of political parties, a political faction is a subgroup within a political party, and an advocacy group is focused on advancing a policy agenda. This is related to other features that sometimes distinguish parties from other political organizations, including a larger membership, greater stability over time, and
8814-783: The first political party in Uganda, and its name was chosen as an homage to the Indian National Congress. As broader suffrage rights and eventually universal suffrage slowly spread throughout democracies, political parties expanded dramatically, and only then did a vision develop of political parties as intermediaries between the full public and the government. Political parties are a nearly ubiquitous feature of modern countries. Nearly all democratic countries have strong political parties, and many political scientists consider countries with fewer than two parties to necessarily be autocratic . However, these sources allow that
8927-433: The following countries are legally constituted as one-party states: A de facto one-party system is one that, while not officially linking a single political party to governmental power, utilizes some means of political manipulation to ensure only one party stays in power. Many different countries have been claimed to be de facto one-party states, with differing levels of agreement between scholars, although most agree that
9040-668: The formation of parties is explicitly banned by law. The existence of political parties may be banned in autocratic countries in order to prevent a turnover in power. For example, in Saudi Arabia , a ban on political parties has been used as a tool for protecting the monarchy. However, parties are also banned in some polities that have long democratic histories, usually in local or regional elections of countries that have strong national party systems. Political parties may also temporarily cease to exist in countries that have either only been established recently, or that have experienced
9153-413: The group of candidates who run for office under a party label. In a broader definition, political parties are the entire apparatus that supports the election of a group of candidates, including voters and volunteers who identify with a particular political party, the official party organizations that support the election of that party's candidates, and legislators in the government who are affiliated with
9266-575: The head of government, the entire party executive may be competing for various positions in the government. For example, in Westminster systems , the largest party that is out of power will form the Official Opposition in parliament, and select a shadow cabinet which (among other functions) provides a signal about which members of the party would hold which positions in the government if the party were to win an election. Citizens in
9379-464: The head of government. In both presidential democracies and parliamentary democracies , the members of a party frequently have substantial input into the selection of party leaders, for example by voting on party leadership at a party conference . Because the leader of a major party is a powerful and visible person, many party leaders are well-known career politicians. Party leaders can be sufficiently prominent that they affect voters' perceptions of
9492-471: The ideologies of political parties include ranges from liberal to authoritarian, from pro-establishment to anti-establishment , and from tolerant and pluralistic (in their behavior while participating in the political arena) to anti-system. Party positions for individual political parties are assessed by different published indices, such as the V-Party Dataset . Though ideologies are central to
9605-530: The introduction of universal suffrage resulted in the creation of worker's parties that later evolved into mass parties; an example is the German Social Democratic Party . These parties represented large groups of citizens who had not previously been represented in political processes, articulating the interests of different groups in society. In contrast to elite parties, mass parties are funded by their members, and rely on and maintain
9718-430: The late 19th century, it was still uncommon for political science to be considered a distinct field from history. The term "political science" was not always distinguished from political philosophy, and the modern discipline has a clear set of antecedents including moral philosophy, political economy, political theology , history, and other fields concerned with normative determinations of what ought to be and with deducing
9831-404: The long run than unaffiliated politicians , so politicians with party affiliations will out-compete politicians without parties. Parties can also align their member's incentives when those members are in a legislature. The existence of a party apparatus can help coalitions of electors to agree on ideal policy choices, whereas a legislature of unaffiliated members might never be able to agree on
9944-448: The merits of every candidate individually. Without political parties, electors would have to individually evaluate every candidate in every election. Parties enable electors to make judgments about just a few groups, and then apply their judgment of the party to its entire slate of candidates. Because it is much easier to become informed about a few parties' platforms than the positions of a multitude of independent candidates, parties reduce
10057-465: The methods of analyzing and anticipating crises, form an important part of political science. Several general indicators of crises and methods were proposed for anticipating critical transitions. Among them, one statistical indicator of crisis, a simultaneous increase of variance and correlations in large groups, was proposed for crisis anticipation and may be successfully used in various areas. Its applicability for early diagnosis of political crises
10170-440: The most successful. These properties are closely connected to other major features of the country's politics, such as how democratic it is, what sorts of restrictions its laws impose on political parties, and what type of electoral systems it uses. Even in countries where the number of political parties is not officially constrained by law, political institutions affect how many parties are viable. For example, democracies that use
10283-432: The national membership and leadership. Parties are typically led by a party leader , who serves as the main representative of the party and often has primary responsibility for overseeing the party's policies and strategies. The leader of the party that controls the government usually becomes the head of government , such as the president or prime minister , and the leaders of other parties explicitly compete to become
10396-434: The nineteenth century before the introduction of universal suffrage. The French political scientist Maurice Duverger first distinguished between elite and "mass" parties, founding his distinction on the differences within the organisational structures of these two types. Elite parties are characterized by minimal and loose organisation, and are financed by fewer larger monetary contributions typically originating from outside
10509-453: The number of parties that it has. In the 1950s Maurice Duverger observed that single-member district single-vote plurality-rule elections tend to produce two-party systems, and this phenomenon came to be known as Duverger's law . Whether or not this pattern is true has been heavily debated over the last several decades. Some political scientists have broadened this idea to argue that more restrictive political institutions (of which first past
10622-420: The party, donate money to it, and vote for its candidates. There are many different ways in which political parties can be structured and interact with the electorate. The contributions that citizens give to political parties are often regulated by law, and parties will sometimes govern in a way that favours the people who donate time and money to them. Many political parties are motivated by ideological goals. It
10735-443: The party. In many countries, the notion of a political party is defined in law, and governments may specify requirements for an organization to legally qualify as a political party. Political parties are distinguished from other political groups or clubs, such as parliamentary groups, because only presidents have control over the political foundations of the party and also they include political factions, or advocacy groups, mostly by
10848-563: The party. Elite parties give little priority to expanding the party's membership base, and its leaders are its only members. The earliest political parties, such as the Democratic-Republicans and the Federalists , are classified as elite parties. A mass party is a type of political party that developed around cleavages in society and mobilized the ordinary citizens or 'masses' in the political process. In Europe,
10961-613: The policies of Indira Gandhi in the 1970s. The formation of the Indian National Congress , which developed in the late 19th century as a pro-independence faction in British India and immediately became a major political party after Indian independence, foreshadowed the dynamic in many newly independent countries; for example, the Uganda National Congress was a pro-independence party and
11074-462: The population and maintaining a presence in the far reaches of their borders. One-party states recognize the trade-off between election victory and gathering valuable data. To account for this, the regimes have been observed placing local nobility in easy-to-win races. One-party states have also been observed using elections to ensure that only the most popular elites get chosen to office. They also gather data from elections to indicate if
11187-523: The post is one example) tend to produce a smaller number of political parties, so that extremely small parties systems – like those with only two parties – tend to form in countries with very restrictive rules. Political scientist Political science is the scientific study of politics . It is a social science dealing with systems of governance and power, and the analysis of political activities, political thought, political behavior , and associated constitutions and laws . Political science
11300-644: The processes, systems and political dynamics of countries and regions of the world, often to raise public awareness or to influence specific governments. Political scientists may provide the frameworks from which journalists, special interest groups, politicians, and the electorate analyze issues. According to Chaturvedy, Political scientists may serve as advisers to specific politicians, or even run for office as politicians themselves. Political scientists can be found working in governments, in political parties, or as civil servants. They may be involved with non-governmental organizations (NGOs) or political movements. In
11413-403: The shift from the traditional mass parties to catch-all parties as a set of developments including the "drastic reduction of the party's ideological baggage" and the "downgrading of the role of the individual party member". By broadening their central ideologies into more open-ended ones, catch-all parties seek to secure the support of a wider section of the population. Further, the role of members
11526-425: The social sciences as a whole, can be described "as a discipline which lives on the fault line between the 'two cultures' in the academy, the sciences and the humanities ." Thus, in most American colleges, especially liberal arts colleges , it would be located within the school or college of arts and sciences . If no separate college of arts and sciences exists, or if the college or university prefers that it be in
11639-554: The state, and the relation of states one to another." As part of a UNESCO initiative to promote political science in the late 1940s, the International Political Science Association was founded in 1949, as well as national associations in France in 1949, Britain in 1950, and West Germany in 1951. In the 1950s and the 1960s, a behavioral revolution stressing the systematic and rigorously scientific study of individual and group behavior swept
11752-421: The study of culture in anthropology. In turn, methodologies that are developed within political science may influence how researchers in other fields, like public health, conceive of and approach political processes and policies. The most common piece of academic writing in generalist political sciences is the research paper, which investigates an original research question . Political science, possibly like
11865-451: The support of organized trade unions . During the wave of decolonization in the mid-20th century, many newly sovereign countries outside of Europe and North America developed party systems that often emerged from their movements for independence. For example, a system of political parties arose out of factions in the Indian independence movement , and was strengthened and stabilized by
11978-422: The theory is an incomplete story of where political parties come from unless it also explains the origins of these social cleavages. An alternative explanation for why parties are ubiquitous across the world is that the formation of parties provides compatible incentives for candidates and legislators. For example, the existence of political parties might coordinate candidates across geographic districts, so that
12091-514: The traditional focuses of other social sciences—for example, when sociological norms or psychological biases are connected to political phenomena. In these cases, political science may either inherit their methods of study or develop a contrasting approach. For example, Lisa Wedeen has argued that political science's approach to the idea of culture, originating with Gabriel Almond and Sidney Verba and exemplified by authors like Samuel P. Huntington , could benefit from aligning more closely with
12204-589: The types of policies they might pursue if they were in power. Ideologies also differentiate parties from one another, so that voters can select the party that advances the policies that they most prefer. A party may also seek to advance an ideology by convincing voters to adopt its belief system. Common ideologies that can form a central part of the identity of a political party include liberalism , conservatism , socialism , communism , anarchism , fascism , feminism , environmentalism , nationalism , fundamentalism , Islamism , and multiculturalism . Liberalism
12317-602: The undergraduate and postgraduate levels, although most but not all undergraduate level education in these sub-fields of political science is generally found in academic concentrations within a political science academic major . Master's-level programs in public administration are professional degrees covering public policy along with other applied subjects; they are often seen as more linked to politics than any other discipline, which may be reflected by being housed in that department. The main national honor society for college and university students of government and politics in
12430-458: The university's public policy school . Most United States colleges and universities offer BA programs in political science. MA or MAT and PhD or EdD programs are common at larger universities. The term political science is more popular in post-1960s North America than elsewhere while universities predating the 1960s or those historically influenced by them would call the field of study government ; other institutions, especially those outside
12543-416: Was also developed. The study of major crises, both political crises and external crises that can affect politics, is not limited to attempts to predict regime transitions or major changes in political institutions. Political scientists also study how governments handle unexpected disasters, and how voters in democracies react to their governments' preparations for and responses to crises. Political science
12656-530: Was demonstrated by the analysis of the prolonged stress period preceding the 2014 Ukrainian economic and political crisis. There was a simultaneous increase in the total correlation between the 19 major public fears in the Ukrainian society (by about 64%) and in their statistical dispersion (by 29%) during the pre-crisis years. A feature shared by certain major revolutions is that they were not predicted. The theory of apparent inevitability of crises and revolutions
12769-419: Was developed by Richard Katz and Peter Mair , who wrote that political parties have turned into "semi-state agencies", acting on behalf of the state rather than groups in society. The term 'cartel' refers to the way in which prominent parties in government make it difficult for new parties to enter, as such forming a cartel of established parties. As with catch-all parties, the role of members in cartel parties
