On the night of 14-15 May 1811, militia officers led by Pedro Juan Caballero and Fulgencio Yegros deposed the Spanish governor at Asuncion and ended colonial rule without bloodshed; both days are still celebrated as Paraguay's independence. The leaders of the province had refused to accept the authority claimed by Buenos Aires after the May Revolution of 1810 and chose instead to govern themselves. A junta was soon formed, dominated in practice by the lawyer Jose Gaspar Rodriguez de Francia, and on 12 October 1813 a congress formally proclaimed the Republic of Paraguay, one of the first enduring republics of the new world. Paraguay's history is rooted in the Guarani peoples of the Parana and Paraguay river basins, whose language remains co-official with Spanish and is spoken by most of the nation today. Spaniards founded Asuncion in 1537, the 'mother of cities' from which much of southern South America was settled, and in the seventeenth and eighteenth centuries Jesuit missions gathered the Guarani into reducciones until the order's expulsion in 1767. Independence from Spain came in May 1811, followed by the long isolationist dictatorship of Jose Gaspar Rodriguez de Francia and the modernising rule of Carlos Antonio Lopez and his son Francisco Solano Lopez, whose War of the Triple Alliance (1864-1870) against Brazil, Argentina and Uruguay devastated the country and killed a vast, disputed share of its population. The twentieth century brought the Chaco War with Bolivia (1932-1935), the thirty-five-year dictatorship of Alfredo Stroessner (1954-1989), and finally a return to democracy and a new constitution in 1992, in an era defined economically by the binational Itaipu hydroelectric dam.
