11850-661: The U.S. territories." Despite disparate systems of confinement, four main institutions dominate: federal prisons , state prisons , local jails, and juvenile correctional facilities . Federal prisons are run by the Federal Bureau of Prisons and hold people who have been convicted of federal crimes, including pretrial detainees. State prisons, run by the official department of correction of each state, hold sentenced people serving prison time (usually longer than one year) for felony offenses. Local jails are county or municipal facilities that incarcerate defendants prior to trial; they also hold those serving short sentences (typically under
12000-402: The U.S., including those that had been in rebellion; at least 27 states had to ratify the amendment for it to come into force. By the end of February, 18 states had ratified the amendment. Among them were the ex-Confederate states of Virginia and Louisiana, where ratifications were submitted by Reconstruction governments. These, along with subsequent ratifications from Arkansas and Tennessee raised
12150-473: The Union"; whence everyone's object should be to restore that relation. Lincoln was assassinated three days later. With Congress out of session, the new president, Andrew Johnson , began a period known as "Presidential Reconstruction", in which he personally oversaw the creation of new state governments throughout the South. He oversaw the convening of state political conventions populated by delegates whom he deemed to be loyal. Three leading issues came before
12300-464: The United States and the peaceful transfer of power , respectively. The Louisiana Purchase of 1803 from France nearly doubled the territory of the United States. Lingering issues with Britain remained , leading to the War of 1812 , which was fought to a draw. Spain ceded Florida and its Gulf Coast territory in 1819. In the late 18th century, American settlers began to expand westward , many with
12450-714: The United States entered the Cold War, where geopolitical tensions between the U.S. and the Soviet Union led the two countries to dominate world affairs . The U.S. utilized the policy of containment to limit the USSR's sphere of influence, and prevailed in the Space Race , which culminated with the first crewed Moon landing in 1969. Domestically, the U.S. experienced economic growth , urbanization , and population growth following World War II . The civil rights movement emerged, with Martin Luther King Jr. becoming
12600-666: The United States has operated as a de facto two-party system , though the parties in that system have been different at different times. The two main national parties are presently the Democratic and the Republican . The former is perceived as relatively liberal in its political platform while the latter is perceived as relatively conservative . In the American federal system , sovereign powers are shared between two levels of elected government: national and state. People in
12750-593: The United States in 2001 by the pan-Islamist militant organization al-Qaeda led to the war on terror , and subsequent military interventions in Afghanistan and Iraq . The cultural impact of the attacks was profound and long-lasting. The U.S. housing bubble culminated in 2007 with the Great Recession , the largest economic contraction since the Great Depression. Coming to a head in
12900-597: The United States of America to Spain" to seek assistance in the Revolutionary War effort. The first known public usage is an anonymous essay published in the Williamsburg newspaper, The Virginia Gazette , on April 6, 1776. By June 1776, the "United States of America" appeared in the Articles of Confederation and the Declaration of Independence . The Second Continental Congress adopted
13050-491: The United States was divided into states that allowed slavery and states that prohibited it . Slavery was implicitly recognized in the original Constitution in provisions such as the Three-fifths Compromise (Article I, Section 2, Clause 3), which provided that three-fifths of each state's enslaved population ("other persons") was to be added to its free population for the purposes of apportioning seats in
13200-593: The United States, despite the usage of "the Americas " as the totality of North and South America. "The States" is an established colloquial shortening of the name, used particularly from abroad; "stateside" is the corresponding adjective or adverb. The first inhabitants of North America migrated from Siberia across the Bering land bridge about 12,000 years ago; the Clovis culture , which appeared around 11,000 BC,
13350-624: The United States, except Iran , North Korea , and Bhutan . Though Taiwan does not have formal diplomatic relations with the U.S., it maintains close unofficial relations. The United States regularly supplies Taiwan with military equipment to deter potential Chinese aggression. Its geopolitical attention also turned to the Indo-Pacific when the United States joined the Quadrilateral Security Dialogue with Australia, India, and Japan. The United States has
13500-484: The United States, some black Americans, particularly in the South, were subjected to other forms of involuntary labor, such as under the Black Codes , white supremacist violence, and selective enforcement of statutes, as well as other disabilities. Many such abuses were given cover by the Amendment's penal labor exclusion. Section 1. Neither slavery nor involuntary servitude, except as a punishment for crime whereof
13650-509: The United States. The American prison system is largely heterogenous, with thousands of relatively independent systems operating across federal, state, local, and tribal levels. In 2023, "these systems [held] almost 2 million people in 1,566 state prisons, 98 federal prisons, 3,116 local jails, 1,323 juvenile correctional facilities, 181 immigration detention facilities, and 80 Indian country jails, as well as in military prisons , civil commitment centers, state psychiatric hospitals, and prisons in
13800-446: The amendment generally made arguments based on federalism and states' rights . Some argued that the proposed change so violated the spirit of the Constitution it would not be a valid "amendment" but would instead constitute "revolution". Representative Chilton A. White , among other opponents, warned that the amendment would lead to full citizenship for blacks. Republicans portrayed slavery as uncivilized and argued for abolition as
13950-680: The amendment mounted and Lincoln urged Congress on in his December 6, 1864 State of the Union Address : "there is only a question of time as to when the proposed amendment will go to the States for their action. And as it is to so go, at all events, may we not agree that the sooner the better?" Lincoln instructed Secretary of State William H. Seward, Representative John B. Alley and others to procure votes by any means necessary, and they promised government posts and campaign contributions to outgoing Democrats willing to switch sides. Seward had
14100-421: The amendment on April 8, 1864, by a vote of 38 to 6; two Democrats, Oregon Senators Benjamin F Harding and James Nesmith voted for the amendment. However, just over two months later on June 15, the House failed to do so, with 93 in favor and 65 against, thirteen votes short of the two-thirds vote needed for passage; the vote split largely along party lines, with Republicans supporting and Democrats opposing. In
14250-491: The amendment would leave broader American society's patriarchal traditions intact. In mid-January 1865, Speaker of the House Schuyler Colfax estimated the amendment to be five votes short of passage. Ashley postponed the vote. At this point, Lincoln intensified his push for the amendment, making direct emotional appeals to particular members of Congress. On January 31, 1865, the House called another vote on
14400-515: The amendment, with neither side being certain of the outcome. With a total of 183 House members ( one seat was vacant after Reuben Fenton was elected governor), 122 would have to vote "aye" to secure passage of the resolution; however, eight Democrats abstained, reducing the number to 117. Every Republican (84), Independent Republican (2), and Unconditional Unionist (16) supported the measure, as well as fourteen Democrats, almost all of them lame ducks, and three Unionists. The amendment finally passed by
14550-457: The contiguous United States are in the State of California, about 84 miles (135 km) apart. At an elevation of 20,310 feet (6,190.5 m), Alaska's Denali is the highest peak in the country and continent. Active volcanoes are common throughout Alaska's Alexander and Aleutian Islands , and Hawaii consists of volcanic islands. The supervolcano underlying Yellowstone National Park in
14700-525: The conventions: secession itself, the abolition of slavery, and the Confederate war debt. Alabama, Florida, Georgia, Mississippi, North Carolina, and South Carolina held conventions in 1865, while Texas' convention did not organize until March 1866. Johnson hoped to prevent deliberation over whether to re-admit the Southern states by accomplishing full ratification before Congress reconvened in December. He believed he could silence those who wished to deny
14850-408: The country continued to expand, the issue of slavery in its new territories became the dominant national issue. The senatorial votes of new states could break the deadlock in the Senate over slavery. The Southern position was that slaves were property and therefore could be moved to the territories like all other forms of property. The 1820 Missouri Compromise provided for the admission of Missouri as
15000-556: The country's GDP. The U.S. has 42% of the world's nuclear weapons —the second-largest share after Russia. The United States has the third-largest combined armed forces in the world, behind the Chinese People's Liberation Army and Indian Armed Forces . The military operates about 800 bases and facilities abroad, and maintains deployments greater than 100 active duty personnel in 25 foreign countries. State defense forces (SDFs) are military units that operate under
15150-469: The country's territory would expand with the admission of new states , rather than the expansion of existing states. The U.S. Constitution was drafted at the 1787 Constitutional Convention to overcome the limitations of the Articles. It went into effect in 1789, creating a federal republic governed by three separate branches that together ensured a system of checks and balances . George Washington
15300-713: The development of self-governance, and the First Great Awakening , a series of Christian revivals , fueled colonial interest in religious liberty . For a century, the American colonists had been providing their own troops and materiel in conflicts with indigenous peoples allied with Britain's colonial rivals , especially France, and the Americans had begun to develop a sense of self-defense and self-reliance separate from Britain. The French and Indian War (1754–1763) took on new significance for all North American colonists after Parliament under William Pitt
15450-414: The dispossession of native inhabitants . As more states were admitted , a North–South division over slavery led to the secession of the Confederate States of America , which fought states remaining in the Union in the 1861–1865 American Civil War . With the victory and preservation of the United States, slavery was abolished nationally . By 1900, the country had established itself as a great power ,
15600-921: The economic situation of most blacks who remained in the south. As the amendment still permitted labor as punishment for convicted criminals, Southern states responded with what historian Douglas A. Blackmon called "an array of interlocking laws essentially intended to criminalize black life". These laws, passed or updated after emancipation, were known as Black Codes . Mississippi was the first state to pass such codes, with an 1865 law titled "An Act to confer Civil Rights on Freedmen". The Mississippi law required black workers to contract with white farmers by January 1 of each year or face punishment for vagrancy. Blacks could be sentenced to forced labor for crimes including petty theft, using obscene language, or selling cotton after sunset. States passed new, strict vagrancy laws that were selectively enforced against blacks without white protectors. The labor of these convicts
15750-507: The effect of these laws waned as political will diminished and the federal government lost authority in the South, particularly after the Compromise of 1877 ended Reconstruction in exchange for a Republican presidency. Southern business owners sought to reproduce the profitable arrangement of slavery with a system called peonage , in which disproportionately black workers were entrapped by loans and compelled to work indefinitely due to
15900-530: The enslaved in Confederate-controlled areas (and thus almost all slaves) were free. When they escaped to Union lines or federal forces (including now-former slaves) advanced south, emancipation occurred without any compensation to the former owners. Texas was the last Confederate-slave territory, where enforcement of the proclamation was declared on June 19, 1865 . In the slave-owning areas controlled by Union forces on January 1, 1863, state action
16050-436: The enslaved population of the South continued to grow, peaking at almost four million in 1861. An abolitionist movement , headed by such figures as William Lloyd Garrison , Theodore Dwight Weld , and Angelina Grimké , grew in strength in the North, calling for the immediate end of slavery nationwide and exacerbating tensions between North and South. The American Colonization Society , an alliance between abolitionists who felt
16200-580: The environment for labor unions to begin to flourish . This period eventually ended with the advent of the Progressive Era , which was characterized by significant reforms. Pro-American elements in Hawaii overthrew the Hawaiian monarchy ; the islands were annexed in 1898. That same year, Puerto Rico , the Philippines , and Guam were ceded to the U.S. by Spain after the latter's defeat in
16350-541: The federal government often applied policies of Indian removal or assimilation . The Trail of Tears (1830–1850) was a U.S. government policy that forcibly removed and displaced most Native Americans living east of the Mississippi River to lands far to the west. These and earlier organized displacements prompted a long series of American Indian Wars west of the Mississippi. The Republic of Texas
16500-606: The first nuclear weapons and used them against the Japanese cities of Hiroshima and Nagasaki in August 1945, ending the war. The United States was one of the " Four Policemen " who met to plan the post-war world , alongside the United Kingdom , Soviet Union , and China . The U.S. emerged relatively unscathed from the war, with even greater economic power and international political influence . After World War II,
16650-665: The first settlement of the Thirteen Colonies in Virginia in 1607. Clashes with the British Crown over taxation and political representation sparked the American Revolution , with the Second Continental Congress formally declaring independence on July 4, 1776. Following its victory in the 1775–1783 Revolutionary War , the country continued to expand westward across North America , resulting in
16800-420: The freedman has not the protection which the master from interest gave him before." W. E. B. Du Bois wrote in 1935: Slavery was not abolished even after the Thirteenth Amendment. There were four million freedmen and most of them on the same plantation, doing the same work they did before emancipation, except as their work had been interrupted and changed by the upheaval of war. Moreover, they were getting about
16950-513: The governors of Mississippi and North Carolina that they could proactively control the allocation of rights to freedmen. Though Johnson obviously expected the freed people to enjoy at least some civil rights, including, as he specified, the right to testify in court, he wanted state lawmakers to know that the power to confer such rights would remain with the states. When South Carolina provisional governor Benjamin Franklin Perry objected to
17100-463: The integration of Army National Guard units and personnel into the U.S. Army and (since 1947) the U.S. Air Force. There are about 18,000 U.S. police agencies from local to national level in the United States. Law in the United States is mainly enforced by local police departments and sheriff departments in their municipal or county jurisdictions. The state police departments have authority in their respective state , and federal agencies such as
17250-478: The issues of how many seceded states had legally valid legislatures; and if there were fewer legislatures than states, if Article V required ratification by three-fourths of the states or three-fourths of the legally valid state legislatures. President Lincoln in his last speech, on April 11, 1865, called the question about whether the Southern states were in or out of the Union a "pernicious abstraction". He declared they were not "in their proper practical relation with
17400-669: The legislation, Congress and the states added additional protections to the Constitution: the Fourteenth Amendment (1868) defining citizenship and mandating equal protection under the law, and the Fifteenth Amendment (1870) banning racial voting restrictions. The Freedmen's Bureau enforced the amendment locally, providing a degree of support for people subject to the Black Codes. Reciprocally,
17550-482: The military draft (leading to the end of conscription in 1973) and wide opposition to U.S. intervention in Vietnam (with the U.S. totally withdrawing in 1975). A societal shift in the roles of women was significantly responsible for the large increase in female paid labor participation during the 1970s, and by 1985 the majority of American women aged 16 and older were employed. The late 1980s and early 1990s saw
17700-612: The most attractive to the population are the most vulnerable. The U.S. is one of 17 megadiverse countries containing large numbers of endemic species : about 17,000 species of vascular plants occur in the contiguous United States and Alaska, and over 1,800 species of flowering plants are found in Hawaii, few of which occur on the mainland. The United States is home to 428 mammal species, 784 birds, 311 reptiles, 295 amphibians , and around 91,000 insect species. There are 63 national parks , and hundreds of other federally managed parks, forests, and wilderness areas , managed by
17850-662: The most violent, the California genocide of thousands of Native inhabitants, lasted into the early 1870s, just as additional western territories and states were created. During the colonial period, slavery had been legal in the American colonies , though the practice began to be significantly questioned during the American Revolution. States in the North enacted abolition laws , though support for slavery strengthened in Southern states , as inventions such as
18000-436: The party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction. Section 2. Congress shall have power to enforce this article by appropriate legislation. Slavery existed and was legal in the United States of America upon its founding in 1776. It was established by European colonization in all of the original thirteen American colonies of British America . Prior to
18150-454: The philosophy of the Declaration of Independence, between 1777 and 1804 every Northern state provided for the immediate or gradual abolition of slavery. (Slavery was never legal in Vermont; it was prohibited in the 1777 constitution creating Vermont, to become the fourteenth state.) Most of the slaves who were emancipated by such legislation were household servants. No Southern state did so, and
18300-408: The policy of redlining later adopted by the federal Home Owners' Loan Corporation . An explosion of technological advancement accompanied by the exploitation of cheap immigrant labor led to rapid economic expansion during the late 19th and early 20th centuries , allowing the United States to outpace the economies of England, France, and Germany combined. This fostered the amassing of power by
18450-443: The political status of former slaves, or their civil relations, would be contrary to the Constitution of the United States." Alabama and Louisiana also declared that their ratification did not imply federal power to legislate on the status of former slaves. During the first week of December, North Carolina and Georgia gave the amendment the final votes needed for it to become part of the Constitution. The first 27 states to ratify
18600-574: The primary colonial grievances was a denial of their rights as Englishmen , particularly the right to representation in the British government that taxed them . To demonstrate their dissatisfaction and resolve, the First Continental Congress met in 1774 and passed the Continental Association , a colonial boycott of British goods that proved effective. The British attempt to then disarm the colonists resulted in
18750-506: The punishment of crimes whereof the party shall have been duly convicted." Though using Henderson's proposed amendment as the basis for its new draft, the Judiciary Committee removed language that would have allowed a constitutional amendment to be adopted with only a majority vote in each House of Congress and ratification by two-thirds of the states (instead of two-thirds and three-fourths, respectively). The Senate passed
18900-420: The resulting debt. Peonage continued well through Reconstruction and ensnared a large proportion of black workers in the South. These workers remained destitute and persecuted, forced to work dangerous jobs and further confined legally by the racist Jim Crow laws that governed the South. Peonage differed from chattel slavery because it was not strictly hereditary and did not allow the sale of people in exactly
19050-515: The rights of African Americans . National infrastructure, including transcontinental telegraph and railroads , spurred growth in the American frontier . From 1865 through 1917 an unprecedented stream of immigrants arrived in the United States, including 24.4 million from Europe. Most came through the port of New York City , and New York City and other large cities on the East Coast became home to large Jewish , Irish , and Italian populations, while many Germans and Central Europeans moved to
19200-614: The rocky Great Basin and Chihuahua , Sonoran , and Mojave deserts. In the northwest corner of Arizona , carved by the Colorado River over millions of years, is the Grand Canyon , a steep-sided canyon and popular tourist destination known for its overwhelming visual size and intricate, colorful landscape. The Sierra Nevada and Cascade mountain ranges run close to the Pacific coast . The lowest and highest points in
19350-449: The same time, many states passed laws to actively prevent blacks from acquiring property. As its first enforcement legislation , Congress passed the Civil Rights Act of 1866 , guaranteeing black Americans citizenship and equal protection of the law, though not the right to vote. The amendment was also used as authorizing several Freedmen's Bureau bills . President Andrew Johnson vetoed these bills, but Congress overrode his vetoes to pass
19500-420: The same wages and apparently were going to be subject to slave codes modified only in name. There were among them thousands of fugitives in the camps of the soldiers or on the streets of the cities, homeless, sick, and impoverished. They had been freed practically with no land nor money, and, save in exceptional cases, without legal status, and without protection. Official emancipation did not substantially alter
19650-576: The scope of the amendment's enforcement clause, Secretary of State Seward responded by telegraph that in fact the second clause "is really restraining in its effect, instead of enlarging the powers of Congress". Politicians throughout the South were concerned that Congress might cite the amendment's enforcement powers as a way to authorize black suffrage. When South Carolina ratified the Amendment in November 1865, it issued its own interpretive declaration that "any attempt by Congress toward legislating upon
19800-522: The six service branches, which are made up of the U.S. Army , Marine Corps , Navy , Air Force , and Space Force . The Coast Guard is administered by the Department of Homeland Security in peacetime and can be transferred to the Department of the Navy in wartime. The United States spent $ 916 billion on its military in 2023, which is by far the largest amount of any country , making up 37% of global military spending and accounting for 3.4% of
19950-545: The sole authority of a state government. SDFs are authorized by state and federal law but are under the command of the state's governor . They are distinct from the state's National Guard units in that they cannot become federalized entities. A state's National Guard personnel, however, may be federalized under the National Defense Act Amendments of 1933 , which created the Guard and provides for
20100-543: The states are also represented by local elected governments , which are administrative divisions of the states. States are subdivided into counties or county equivalents , and further divided into municipalities . The District of Columbia is a federal district containing the U.S. capital, Washington, D.C. .

The United States has an established structure of foreign relations, and it has
20250-451: The structure and responsibilities of the national federal government and its relationship with the individual states. The U.S. Constitution is the world's oldest national constitution still in effect (from March 4, 1789). Composed of three branches, all headquartered in Washington, D.C., the federal government is the national government of the United States. It is regulated by a strong system of checks and balances . The three-branch system
20400-527: The usual signatures of the Speaker of the House and the President of the Senate, President Lincoln wrote the word "Approved" and added his signature to the joint resolution on February 1, 1865. On February 7, Congress passed a resolution affirming that the Presidential signature was unnecessary. The Thirteenth Amendment was the first of two ratified amendments to be signed by a President, the second being
20550-582: The world's fourth-longest river system , runs predominantly north–south through the heart of the country. The flat and fertile prairie of the Great Plains stretches to the west, interrupted by a highland region in the southeast. The Rocky Mountains , west of the Great Plains, extend north to south across the country, peaking at over 14,000 feet (4,300 m) in Colorado . Farther west are
20700-583: The world's second-largest diplomatic corps as of 2024 . It is a permanent member of the United Nations Security Council , and home to the United Nations headquarters . The United States is a member of the G7 , G20 , and OECD intergovernmental organizations. Almost all countries have embassies and many have consulates (official representatives) in the country. Likewise, nearly all countries host formal diplomatic missions with
20850-461: The world's third-largest land area , largest exclusive economic zone , and third-largest population , exceeding 334 million. Its three largest metropolitan areas are New York , Los Angeles , and Chicago , and its three most populous states are California , Texas , and Florida . Paleo-Indians migrated across the Bering land bridge more than 12,000 years ago, and formed various civilizations and societies . British colonization led to
21000-444: The world's oldest surviving federation, and its presidential system of national government has been adopted, in whole or in part, by many newly independent states worldwide following their decolonization . It is a liberal representative democracy "in which majority rule is tempered by minority rights protected by law ". The Constitution of the United States serves as the country's supreme legal document , also establishing
21150-553: The world's tornadoes occur in the country , mainly in Tornado Alley . Overall, the United States receives more high-impact extreme weather incidents than any other country. Extreme weather became more frequent in the U.S. in the 21st century, with three times the number of reported heat waves as in the 1960s. In the American Southwest , droughts became more persistent and more severe. The regions considered as
21300-721: The world, with almost 2 million people incarcerated . An analysis of the World Health Organization Mortality Database from 2010 showed U.S. homicide rates "were 7 times higher than in other high-income countries, driven by a gun homicide rate that was 25 times higher". Thirteenth Amendment to the United States Constitution The Thirteenth Amendment ( Amendment XIII ) to the United States Constitution abolished slavery and involuntary servitude , except as punishment for
21450-513: Was annexed in 1845, and the 1846 Oregon Treaty led to U.S. control of the present-day American Northwest . Victory in the Mexican–American War resulted in the 1848 Mexican Cession of California, Nevada, Utah, and much of present-day Colorado and the American Southwest . The California gold rush of 1848–1849 spurred a huge migration of white settlers to the Pacific coast, leading to even more confrontations with Native populations. One of
21600-759: Was adopted on July 4, 1776. The political values of the American Revolution included liberty , inalienable individual rights ; and the sovereignty of the people ; supporting republicanism and rejecting monarchy , aristocracy , and all hereditary political power; civic virtue ; and vilification of political corruption . The Founding Fathers of the United States , who included Washington, Jefferson, John Adams , Benjamin Franklin , Alexander Hamilton , John Jay , James Madison , Thomas Paine , and many others, were inspired by Greco-Roman , Renaissance , and Enlightenment philosophies and ideas. The Articles of Confederation were ratified in 1781 and established
21750-522: Was elected the country's first president under the Constitution, and the Bill of Rights was adopted in 1791 to allay skeptics' concerns about the power of the more centralized government. His resignation as commander-in-chief after the Revolutionary War and his later refusal to run for a third term as the country's first president established a precedent for the supremacy of civil authority in
21900-472: Was felt quickly. When the Thirteenth Amendment became operational, the scope of Lincoln's 1863 Emancipation Proclamation was widened to include the entire nation. Although the majority of Kentucky's slaves had been emancipated, 65,000–100,000 people remained to be legally freed when the amendment went into effect on December 18. In Delaware, where a large number of slaves had escaped during the war, nine hundred people became legally free. With slavery abolished,
22050-404: Was subsequently ratified by the other states, as follows: With the ratification by Mississippi in 1995, and certification thereof in 2013, the amendment was finally ratified by all states having existed at the time of its adoption in 1865. The immediate impact of the amendment was to make the entire pre-war system of chattel slavery in the U.S. illegal. The impact of the abolition of slavery
22200-803: Was then sold to farms, factories, lumber camps , quarries, and mines. After its ratification of the Thirteenth Amendment in November 1865, the South Carolina legislature immediately began to legislate Black Codes. The Black Codes created a separate set of laws, punishments, and acceptable behaviors for anyone with more than one black great-grandparent. Under these Codes, Blacks could only work as farmers or servants and had few Constitutional rights. Restrictions on black land ownership threatened to make economic subservience permanent. Some states mandated indefinitely long periods of child "apprenticeship". Some laws did not target blacks specifically, but instead affected farm workers, most of whom were black. At
22350-471: Was uncertain. To ensure that abolition was beyond legal challenge, an amendment to the Constitution to that effect was drafted. On April 8, 1864, the Senate passed an amendment to abolish slavery. After one unsuccessful vote and extensive legislative maneuvering by the Lincoln administration, the House followed suit on January 31, 1865. The measure was swiftly ratified by nearly all Northern states , along with
22500-633: Was used to abolish slavery. The exceptions were Kentucky and Delaware , and to a limited extent New Jersey , where chattel slavery and indentured servitude were finally ended by the Thirteenth Amendment in December 1865. In contrast to the other Reconstruction Amendments, the Thirteenth Amendment has rarely been cited in case law, but it has been used to strike down peonage and some race-based discrimination as "badges and incidents of slavery". The Thirteenth Amendment has also been invoked to empower Congress to make laws against modern forms of slavery, such as sex trafficking . From its inception in 1776,
