Uruguayan Democratization
A history of Uruguayan democratization.
Banda Oriental
The Uruguay River basin was sparsely populated by nomadic peoples. The river itself served as the legal boundary between Spanish and Portuguese land claims. In actuality though, control over the eastern bank (Banda Oriental) traded hands repeatedly. Early on, the Portuguese exploited the remoteness of the region and settled Colonia del Sacramento opposite Buenos Aires on the Río de la Plata, securing a trade and smuggling route on the river. This city traded hands repeatedly, including a cession back to Portugal through the Treaty of Utrecht. On the other hand, Portuguese control over the region was waning in the 18th century, to which point the Spanish settled a fortification at Montevideo to consolidate control.
Territorial conflict in this region ultimately forced the abandonment of the legal complex formed by the Treaty of Tordesillas, the Treaty of Zaragoza, and the papal bull Inter caetera. The Treaty of Madrid in 1750 set the border at the Uruguay River. The seven Jesuit missions that had been established on the eastern bank (the so-called Misiones Orientales) were ordered to relocate west. The Guaraní nation refused the relocation however, and Sepé Tiaraju led a militarized defense. The Guaraní War lasted from 1754 to 1756 and ultimately ended in victory for the joint Spanish and Portuguese forces. However, the Seven Years War broke out that same year; Charles III rose to the throne in 1759 and immediately resolved to renege on the treaty. This theater of the war is sometimes known as the Fantastic War. The Treaty of Paris in 1763 restored the territory to Spain. Portugal soon resumed conflict but the Spanish-Portuguese War ended in decisive Spanish victory. The First Treaty of San Ildefonso in 1777 confirmed Spanish control.
The viceroyalty of the Río de la Plata was established in 1776 with Buenos Aires as its capital. Banda Oriental was incorporated into this viceroyalty, but it remained a substantially independent region. Furthermore, as part of the Napoleonic Wars, the British repeatedly invaded Buenos Aires. There were also fears that the Portuguese, with their royal court relocated to Brazil from 1807, would resume regional conflict. The failure of the Junta of Seville and the emergence of a provisional Primera Junta in Buenos Aires were the final blows. José Gervasio Artigas led the Union of Free Peoples (Unión de los Pueblos Libres) and held effective power in Montevideo. They declared independence from Spain in 1815 and established a federalist government in the Federal League (Liga Federal). Brazil did in fact invade however, and ultimately crushed the league.
Under Portuguese (and after 1822 Brazilian) rule the region became known as Cisplatina. The Cisplatine War then broke out from Argentine agitation, although their forces were unable to meaningfully advance. Nonetheless, the Treaty of Montevideo in 1828 established Uruguay as a state independent of both Brazil and Argentina.
Uruguayan Civil War
The early politics of Uruguay were dominated by the conservative Blancos and the liberal Colorados. These labels come from their uniforms during the Uruguayan Civil War which began almost immediately.
Fructuoso Rivera served as the first president. Aside from two insurrections led by Juan Lavalleja, the new country saw peace. Manuel Oribe succeeded him in 1835 and brought in dramatic policy shifts; he granted amnesty to Lavalleja and purged Rivera and his supporters from the Army. He was also a known ally of Juan Manuel de Rosas.
Rivera began organizing a rebellion the next year, drawing on the variety of exiled liberal movements that had settled in Montevideo (especially the Argentine Unitarios). He directed his supporters to wear blue and later red ribbons, in contrast to the white Army uniforms. These Colorados fled into the Riograndense Republic but returned to seize power in 1838. The next year they invaded Argentina. The front quickly collapsed however, and Montevideo was beseiged for 9 years.
Montevideo attracted international attention during this protracted stalemate. Several foreign legions were raised. The most famous of these was the Italian Foreign Legion a.k.a. the Redshirts, led by Giuseppe Garibaldi. Beginning in 1845, the British and French also intervened by blockading Buenos Aires and occupying the Río de la Plata. They withdrew after securing a treaty with Argentina in 1850 however.
In 1851, Justo José de Urquiza launched a rebellion within Argentina and Brazil joined the war on Colorado's side. This stage of the conflict is commonly referred to as the Platine War. Oribe was quickly defeated and de Rosas was forced to stand down within a year.
The treaties negotiated between Uruguay and Brazil at this time created their modern border following the Quaraí River (Rio Quaraí, Río Cuareím) and the Jaguarão River (Rio Jaguarão, Río Yaguarón). Uruguay ceded all land north of the Quaraí and recognized Brazil as having exclusive navigation on the Jaguarão (as it is only navigable up to the town of Jaguarão).
