The Palouse River flows from northern Idaho into southeast Washington through the Palouse region, named for the river. The river originates in Idaho in northeastern Latah County , in

202-590: A constitution for universal representation under a constitutional monarchy was declared, but after the fall of the Bonapartist regime, the Spanish king dismissed the Cortes Generales, set on ruling as an absolute monarch . The French occupation of mainland Spain created an opportunity for overseas criollo elites who resented the privilege towards Peninsular elites and demanded retroversion of

303-515: A comment on the Komatsu analysis, Brian Atwater and colleagues observed substantial evidence for multiple large floods, including mud cracks and animal burrows in lower layers, which were filled by sediment from later floods. Further, evidence for multiple flood flows up sidearms of Glacial Lake Columbia spread over many centuries has been found. They also pointed out that the discharge point from Lake Columbia varied with time, originally flowing across

The word in question actually means " Hyrax ", possibly due to the Phoenicians confusing the two animals. There is also the claim that "Hispania" derives from the Basque word Ezpanna , meaning "edge" or "border", another reference to the fact that the Iberian Peninsula constitutes the southwest corner of

505-615: A puppet kingdom satellite to the French Empire was installed with Joseph Bonaparte as king. The 2 May 1808 revolt was one of many uprisings across the country against the French occupation. These revolts marked the beginning of a devastating war of independence against the Napoleonic regime. Further military action by Spanish armies, guerrilla warfare and an Anglo-Portuguese allied army, combined with Napoleon's failure on

606-532: A reaction against the gallicised elites and following defeat in the field, peace was made with France in 1795 at the Peace of Basel in which Spain lost control over two-thirds of the island of Hispaniola . In 1807, a secret treaty between Napoleon and the unpopular prime minister led to a new declaration of war against Britain and Portugal. French troops entered the country to invade Portugal but instead occupied Spain's major fortresses. The Spanish king abdicated and

707-761: A resolution in favour of democracy. With Franco's death in November 1975, Juan Carlos succeeded to the position of King of Spain and head of state in accordance with the Francoist law. With the approval of the new Spanish Constitution of 1978 and the restoration of democracy , the State devolved much authority to the regions and created an internal organisation based on autonomous communities . The Spanish 1977 Amnesty Law let people of Franco's regime continue inside institutions without consequences, even perpetrators of some crimes during transition to democracy like

808-458: A separate country socially, politically, legally, and in currency and language. Habsburg Spain was one of the leading world powers throughout the 16th century and most of the 17th century, a position reinforced by trade and wealth from colonial possessions and became the world's leading maritime power . It reached its apogee during the reigns of the first two Spanish Habsburgs— Charles V/I (1516–1556) and Philip II (1556–1598). This period saw

909-744: A series of victories against England in the Anglo-Spanish War of 1585–1604 . However, during the middle decades of the 17th century Spain's maritime power went into a long decline with mounting defeats against the Dutch Republic ( Battle of the Downs ) and then England in the Anglo-Spanish War of 1654–1660 ; by the 1660s it was struggling to defend its overseas possessions from pirates and privateers. The Protestant Reformation increased Spain's involvement in religiously charged wars, forcing ever-expanding military efforts across Europe and in

As a reflection of its large cultural wealth , Spain is the world's second-most visited country , has one of the world's largest numbers of World Heritage Sites , and it is the most popular destination for European students. Its cultural influence extends to over 600 million Hispanophones , making Spanish

1414-596: The 12 April 1931 municipal elections . These gave a resounding victory to the Republican-Socialist candidacies in large cities and provincial capitals, with a majority of monarchist councilors in rural areas. The king left the country and the proclamation of the Republic on 14 April ensued, with the formation of a provisional government. A constitution for the country was passed in October 1931 following

1515-705: The Amazon River ). Alternate estimates for the peak flow rate of the largest flood range up to 17 cubic kilometers per hour. The maximum flow speed approached 36 meters/second (130 km/h or 80 mph). Within the Columbia River drainage basin , detailed investigation of the Missoula floods' glaciofluvial deposits , informally known as the Hanford formation , has documented the presence of Middle and Early Pleistocene Missoula flood deposits within

In the Basque Country, moderate Basque nationalism coexisted with a radical nationalist movement led by the armed organisation ETA until the latter's dissolution in May 2018. The group was formed in 1959 during Franco's rule but had continued to wage its violent campaign even after the restoration of democracy and the return of

2626-667: The Potholes Cataract . Bretz coined the term Channeled Scablands in 1923 to refer to the area near the Grand Coulee , where massive erosion had cut through basalt deposits. Bretz published a paper in 1923 arguing that the Channeled Scablands in Eastern Washington were caused by massive flooding in the distant past. Bretz's view, which was seen as arguing for a catastrophic explanation of

The Spanish Empire reached a global scale and spread across all continents, underpinning the rise of a global trading system fueled primarily by precious metals . In the 18th century, the Bourbon reforms centralized mainland Spain. In the 19th century, after the Napoleonic occupation and the victorious Spanish War of independence ,

3333-400: The 11th century, the Caliphate of Córdoba collapsed, fracturing into a series of petty kingdoms ( Taifas ), often subject to the payment of a form of protection money ( Parias ) to the Northern Christian kingdoms, which otherwise undertook a southward territorial expansion. The capture of the strategic city of Toledo in 1085 marked a significant shift in the balance of power in favour of

Shaw's team of geologists reviewed the sedimentary sequences of the Touchet beds and concluded that the sequences do not automatically imply multiple floods separated by decades or centuries. Rather, they proposed that sedimentation in

3535-403: The Christian kingdoms. The arrival from North Africa of the Islamic ruling sects of the Almoravids and the Almohads achieved temporary unity upon the Muslim-ruled territory, with a stricter, less tolerant application of Islam, and partially reversed some Christian territorial gains. The Kingdom of León was the strongest Christian kingdom for centuries. In 1188, the first form (restricted to

The dating for Waitt's proposed separation of layers into sequential floods has been supported by subsequent paleomagnetism studies, which support a 30–40 year interval between depositions of Mount St. Helens' ash, and hence flood events, but do not preclude an up to 60-year interval. Offshore deposits on

3939-496: The European continent. Archaeological research at Atapuerca indicates the Iberian Peninsula was populated by hominids 1.3 million years ago. Modern humans first arrived in Iberia from the north on foot about 35,000 years ago. The best-known artefacts of these prehistoric human settlements are the paintings in the Altamira cave of Cantabria in northern Iberia, which were created from 35,600 to 13,500 BCE by Cro-Magnon . Archaeological and genetic evidence suggests that

4040-479: The Glacial Lake Missoula basin resulted from jökulhlaups draining into Lake Missoula from British Columbia to the north. Further, Shaw's team proposed the scabland flooding might have partially originated from an enormous subglacial reservoir that extended over much of central British Columbia, particularly including the Rocky Mountain Trench , which may have discharged by several paths, including one through Lake Missoula. This discharge, if occurring concurrently with

Precious metals , spices, luxuries, and previously unknown plants brought to the metropole played a leading part in transforming the European understanding of

4343-413: The Mediterranean. By the middle decades of a war- and plague -ridden 17th-century Europe, the Spanish Habsburgs had enmeshed the country in continent-wide religious-political conflicts. These conflicts drained it of resources and undermined the economy generally. Spain managed to hold on to most of the scattered Habsburg empire, and help the imperial forces of the Holy Roman Empire reverse a large part of

Upon the conclusion of the Granada War , the Nasrid Sultanate of Granada (the remaining Muslim-ruled polity in the Iberian Peninsula after 1246) capitulated in 1492 to the military strength of the Catholic Monarchs , and it was integrated from then on in the Crown of Castile. In 1469, the crowns of the Christian kingdoms of Castile and Aragon were united by the marriage of their monarchs, Isabella I and Ferdinand II, respectively. In 1492, Jews were forced to choose between conversion to Catholicism or expulsion; as many as 200,000 Jews were expelled from Castile and Aragon . The year 1492 also marked

Further, Shaw and the team proposed that the rhythmic Touchet beds result from multiple pulses or surges within a larger flood. In 2000, a team led by Komatsu simulated the floods numerically with a 3-dimensional hydraulic model. They based the Glacial Lake Missoula discharge rate on the rate predicted for

For example, their calculated water depth at the Pasco Basin–Wallula Gap transition zone is about 190 m, significantly less than the 280–300 m flood depth indicated by high-water marks. They concluded that a flood of ~10 m /s could not have made the observed high-water marks. In

The maximum flow speed approached 36 meters/second (130 km/h or 80 mph). Up to 1.9×10 joules of potential energy were released by each flood (the equivalent of 4,500 megatons of TNT ). For comparison, this is 90 times more powerful than

These political divisions finally converged in the 20th century with the Spanish Civil War , giving rise to the Francoist dictatorship that lasted until 1975. With the restoration of democracy and its entry into the European Union, the country experienced an economic boom that profoundly transformed it socially and politically. Since

The Geological Society of Washington, D.C , invited the young Bretz to present his previously published research at a January 12, 1927, meeting where several other geologists presented competing theories. Another geologist at the meeting, J.T. Pardee , had worked with Bretz and had evidence of an ancient glacial lake that lent credence to Bretz's theories. Bretz defended his theories, which kicked off an acrimonious 40-year debate over

Thousands were imprisoned after the civil war in Francoist concentration camps . The regime remained nominally "neutral" for much of

7777-557: The majority of the population of Al-Andalus by the end of the 10th century. A series of Viking incursions raided the coasts of the Iberian Peninsula in the 9th and 10th centuries. The first recorded Viking raid on Iberia took place in 844; it ended in failure with many Vikings killed by the Galicians' ballistas ; and seventy of the Vikings' longships captured on the beach and burned by the troops of King Ramiro I of Asturias . In

7878-704: The meseta; however, due to the bellicose inland tribes, the Carthaginians settled on the coasts of the Iberian Peninsula. During the Second Punic War , roughly between 210 and 205 BCE, the expanding Roman Republic captured Carthaginian trading colonies along the Mediterranean coast. Although it took the Romans nearly two centuries to complete the conquest of the Iberian Peninsula , they retained control of it for over six centuries. Roman rule

7979-668: The military carried out a coup d'état that triumphed in only part of the country. The situation led to a civil war, in which the territory was divided into two zones: one under the authority of the Republican government , that counted on outside support from the Soviet Union and Mexico (and from International Brigades ), and the other controlled by the putschists (the Nationalist or rebel faction ), most critically supported by Nazi Germany and Fascist Italy . The Republic

8080-440: The most powerful nuclear weapon ever detonated, the 50-megaton " Tsar Bomba ". The cumulative effect of the floods was to excavate 210 cubic kilometres (50 cu mi) of loess, sediment, and basalt from the Channeled Scablands of eastern Washington and to transport it downstream. The multiple flood hypothesis was first proposed by R.B. Waitt Jr. in 1980. Waitt argued for a sequence of 40 or more floods. Waitt's proposal

8181-604: The nobles benefited from feudalism . Muslim strongholds in the Guadalquivir Valley such as Córdoba (1236) and Seville (1248) fell to Castile in the 13th century. The County of Barcelona and the Kingdom of Aragon entered in a dynastic union and gained territory and power in the Mediterranean. In 1229, Majorca was conquered, so was Valencia in 1238. In the 13th and 14th centuries, the North-African Marinids established some enclaves around

8282-609: The now-dry Washtucna Coulee directly into the Columbia River . The present-day canyon was created when the Missoula Floods overtopped the northern drainage divide of the ancestral Palouse River, diverting it to the current course to the Snake River by eroding a new, deeper channel. The area is characterized by interconnected and hanging flood-created coulees, cataracts, plunge pools, kolk created potholes, rock benches, buttes and pinnacles typical of scablands. Missoula Floods The Missoula floods (also known as

8383-480: The only American colonies Spain held were Cuba and Puerto Rico . The Napoleonic War left Spain economically ruined, deeply divided and politically unstable. In the 1830s and 1840s, Carlism (a reactionary legitimist movement supportive of an alternative Bourbon branch), fought against the government forces supportive of Queen Isabella II 's dynastic rights in the Carlist Wars . Government forces prevailed, but

8484-582: The origin of the Scablands. Both Pardee and Bretz continued their research over the next 30 years, collecting and analyzing evidence that led them to identify Lake Missoula as the source of the Spokane flood and creator of the channeled scablands. After Pardee studied the canyon of the Flathead River , he estimated that flood waters above 45 miles per hour (72 km/h) would be required to roll

8585-411: The period around the turn of the century was one of increasing prosperity, the 20th century brought little social peace. Spain played a minor part in the scramble for Africa . It remained neutral during World War I . The heavy losses suffered by the colonial troops in conflicts in northern Morocco against Riffians forces brought discredit to the government and undermined the monarchy. Industrialisation,

8686-410: The pressure at the bottom of the ice dam increased enough to lower the freezing point of water below the temperature of the ice forming the dam. This allowed liquid water to seep into minuscule cracks present in the ice dam. Over a period of time, the friction from water flowing through these cracks generated enough heat to melt the ice walls and enlarge the cracks. This allowed more water to flow through

8787-591: The province of Baetica took place. The Germanic Suebi and Vandals , together with the Sarmatian Alans , entered the peninsula after 409, weakening the Western Roman Empire's jurisdiction over Hispania. The Suebi established a kingdom in north-western Iberia, whereas the Vandals established themselves in the south of the peninsula by 420 before crossing over to North Africa in 429. As

8888-581: The rebels also added. The name of " Movimiento Nacional ", sometimes understood as a wider structure than the FET y de las JONS proper, largely imposed over the later's name in official documents along the 1950s. After the war Spain was politically and economically isolated, and was kept out of the United Nations. This changed in 1955, during the Cold War period, when it became strategically important for

8989-460: The reduction of export tariffs. Projects of agricultural colonisation with new settlements took place in the south of mainland Spain. Enlightenment ideas began to gain ground among some of the kingdom's elite and monarchy. In 1793, Spain went to war against the revolutionary new French Republic as a member of the first Coalition . The subsequent War of the Pyrenees polarised the country in

9090-589: The remaining Muslim population to become nominally Christian Moriscos . About four decades after the War of the Alpujarras (1568–1571), over 300,000 moriscos were expelled , settling primarily in North Africa. The unification of the crowns of Aragon and Castile by the marriage of their sovereigns laid the basis for modern Spain and the Spanish Empire, although each kingdom of Spain remained

9191-537: The root of the term span is the Phoenician word spy , meaning "to forge metals ". Therefore, i-spn-ya would mean "the land where metals are forged". It may be a derivation of the Phoenician I-Shpania , meaning "island of rabbits", "land of rabbits" or "edge", a reference to Spain's location at the end of the Mediterranean; Roman coins struck in the region from the reign of Hadrian show

9292-652: The sovereignty to the people . Starting in 1809 the American colonies began a series of revolutions and declared independence, leading to the Spanish American wars of independence that put an end to the metropole's grip over the Spanish Main . Attempts to re-assert control proved futile with opposition not only in the colonies but also in the Iberian peninsula and army revolts followed. By the end of 1826,

9393-481: The top of the Touchet beds. The two layers of volcanic ash are separated by 1–10 centimetres (0.4–3.9 in) of airborne nonvolcanic silt. The tephra is Mount St. Helens ash that fell in Eastern Washington. By analogy, since there were 40 layers with comparable characteristics at Burlingame Canyon, Waitt argued they all could be considered to have similar separation in deposition time. The controversy about whether

9494-453: The western area of the Pyrenees mountain range and adjacent areas; Phoenician-influenced Tartessians flourished in the southwest; and Lusitanians and Vettones occupied areas in the central west. Several cities were founded along the coast by Phoenicians , and trading outposts and colonies were established by Greeks in the East. Eventually, Phoenician- Carthaginians expanded inland towards

9595-419: The western empire disintegrated, the social and economic base became greatly simplified; the successor regimes maintained many of the institutions and laws of the late empire, including Christianity and assimilation into the evolving Roman culture. The Byzantines established an occidental province, Spania , in the south, with the intention of reviving Roman rule throughout Iberia. Eventually, however, Hispania

9696-468: The world's second-most spoken native language and the world's most widely spoken Romance language . Spain is a secular parliamentary democracy and a constitutional monarchy , with King Felipe VI as head of state . A developed country , it is a major advanced capitalist economy, with the world's fifteenth-largest by both nominal GDP and PPP . Spain is a member of the United Nations ,

9797-630: Was based mainly on analysis from glacial lake bottom deposits in Ninemile Creek and the flood deposits in Burlingame Canyon. His most compelling argument for separate floods was that the Touchet bed deposits from two successive floods were found to be separated by two layers of volcanic ash ( tephra ), with the ash separated by a fine layer of windblown dust deposits, located in a thin layer between sediment layers ten rhythmites below

9898-605: Was bound together by law, language, and the Roman road . The cultures of the pre-Roman populations were gradually Romanised (Latinised) at different rates depending on what part of the peninsula they lived in, with local leaders being admitted into the Roman aristocratic class. Hispania (the Roman name for the Iberian Peninsula) served as a granary for the Roman market, and its harbours exported gold, wool , olive oil , and wine. Agricultural production increased with

9999-509: Was founded in 1888. In the anarcho-syndicalist trend of the labour movement in Spain, Confederación Nacional del Trabajo was founded in 1910 and Federación Anarquista Ibérica in 1927. Catalanism and Vasquism, alongside other nationalisms and regionalisms in Spain, arose in that period: the Basque Nationalist Party formed in 1895 and Regionalist League of Catalonia in 1901. Political corruption and repression weakened

10100-562: Was not supported by the Western powers due to the British-led policy of non-intervention . General Francisco Franco was sworn in as the supreme leader of the rebels on 1 October 1936. An uneasy relationship between the Republican government and the grassroots anarchists who had initiated a partial social revolution also ensued. The civil war was viciously fought and there were many atrocities committed by all sides . The war claimed

10201-679: Was reunited under Visigothic rule . From 711 to 718, as part of the expansion of the Umayyad Caliphate which had conquered North Africa from the Byzantine Empire , nearly all of the Iberian Peninsula was conquered by Muslims from across the Strait of Gibraltar, resulting in the collapse of the Visigothic Kingdom. Only a small area in the mountainous north of the peninsula stood out of the territory seized during
