[THIS IS CONSIDERED NO LONGER CANON]
(we'll see if I get to update it to the current version...)
18081: situation of the Viceroyalty of River Plate before the Schism.
18082: after Ferdinand's arrival to New Spain, Spanish officers in the Americas are forced to decide their loyalties. Santiago de Liniers, Viceroy of River Plate, declares his loyalty to Charles V due to the animadversion the porteños have towards the British after the invasions of 1806/7. The Portuguese begin an invasion of the Eastern Missions with Ferdinand's approval.
1809: local authorities in the Upper Perú, under theoretical rule from Buenos Aires, defect to the Fernandist camp. The comercial elites of Buenos Aires, damaged by the British blockade, organize a coup against Liniers, installing Montevideo Governor Francisco Javier de Elio, sympathetic to the Fernandist cause, as the new Viceroy. The event will be known as the June Revolution.
1810: Liniers retreats to Córdoba with his followers while most of the Province of Buenos Aires accepts the new viceroyal authority. The departure of Elio to Buenos Aires left a vacuum in the city of Montevideo, that elects a Cabildo to govern itself and appoints Joaquín de Soria as governor without consulting the capital. The Province of Potosí declares for Ferdinand. In Santiago de Chile, partially inspired by the events in Buenos Aires, the local criollos depose the Captain General and install a Junta that recognizes Charles V as the legitimate King.
1811: viceroy Elio organizes an army to subjugate the Province of Missiones with Portuguese help. A detachment is sent north to pacify the Province of Asunción del Paraguay, which has sent letters rejecting the new viceroyal authority, while another one occupies the Eastern Bank of the Uruguay and besieges Montevideo. The Junta forces in Chile defeat the authorities and occupy the region around Santiago.
1812: northern Chile falls to the Junta of Santiago. The victory over Viceroyal and Portuguese Forces emboldened the Paraguayan criollos to celebrate a Congress in Asunción, gaining track the independentist ideas sponsored by Doctor José Gaspar Rodríguez de Francia. The Congress decided to declare Paraguay an independent republic and notified Carlist Governor Bernardo Velasco, who, overwhelmed and dependent on the support of criollos, is forced to accept a triunvirate with Doctor Francia and Juan Valerian Zeballos.
1813: southern Chile falls to the Junta of Santiago, while the province of Potosí is also occupied by a Chilean army. Paraguayan forces manage to liberate the northernmost Guaraní Missions from the Portuguese. The army of Viceroy Liniers advances towards Buenos Aires, capturing the city of Santa Fe.
1814: the Fernandist Army of the Plate sent from the Viceroyalty of Perú pushes Chilean forces out of Potosí and begins to invade the Province of Salta. Liniers' army retakes the region between the rivers Paraná and Uruguay, but is unable to push into Buenos Aires. The Eastern Bank of the Uruguay continues under Elio's control, except for the city of Montevieo, that resists the siege.
18151: Elio's forces suffer a devisive defeat and Liniers' army manages to cross the Uruguay. Unable to sustain the situation, Fernandist forces retire from Montevideo as Elio's authority collapses outside the surroundings of Buenos Aires.
18152: when the news of the final defeat of Napoleon and Charles V's renounce to Spanish America arrive, Liniers' authority collapses. The main cities suffer revolutions that put cabildos in charge. In Córdoba, Liniers' is deposed and an assembly of deputies of every province is called by the newly constituted revolutonary Junta. The Eastern Bank of the Uruguay, under the government of the Junta of Montevideo, choses the prestigious officer José Gervasio Artigas, from the militia regiment of the Blandengues, as the replacement of Joaquín de Soria. Paraguayan forces continue pushing to Portuguese-occupied Missiones. The Junta of Santiago declares the independence of Chile as a republic.
1816: Elio is deposed by a popular revolt in Buenos Aires as the Army of the Plate reconquers the Province of Salta. Alarmed, the Junta of Córdoba flies to the capital and rebrands itself as the National Junta of the United Republic of the River Plate, declaring independence. The celebration of the Assembly is postponed until all the provinces are free to elect representatives, a move that doesn't sit well in Entrerríos, Corrientes and the Eastern Province.
1817: a new army, led by the newly-arrived and British-supported revolutonary José de San Martín, is organized by the National Junta in Buenos Aires and sent north to repel the Army of the Plate. Artigas' Eastern Army liberates the southern Missions from the Portuguese forces, and the caudillo proposes a pact to Paraguay and the provinces of Entrerríos, Corrientes and Misiones to defend federalism in the future Constitutional Assembly.
1818: the Army of the North obliterates the Army of the Plate, liberating Salta. The advances of Artigas lead the Portuguese to seek an armistice with Paraguay, dividing northern Misiones with them and recognizing their independence. Artigas and the federals accept Paraguayan independence.
1819: Fernandist authority collapses in Upper Perú, no new attempts to restore Bourbon control over the country will be carried out. The National Assembly is convened in Córdoba under the tutelage of the popular General San Martín. Altough the representatives favoring a federal organization are more numerous, unitaries manage to pass the division of the extense province of Córdoba into multiple ones to achieve a unitary majority, causing the representatives of Entrerríos, Corrientes, Misiones and Eastern Bank to walk away. The Unitary Assembly sends a letter to Artigas demanding him to subject to its authority and to put the Eastern Army under its control, but Artigas, still at war with the Portuguese and fearing plans to sideline federalism, rejects. This is considered the end of the Argentinian War of Independence, and the beginning of the Argentinian Civil War.
