The wars resulted from the unresolved disputes associated with the French Revolution and the Revolutionary Wars, which had raged on for years before concluding with the Treaty of Amiens in 1802. The resumption of hostilities the following year paved the way for more than a decade of constant warfare often categorized into five conflicts: the War of the Third Coalition (1805), the War of the Fourth Coalition (1806-7), the War of the Fifth Coalition (1809), the War of the Sixth Coalition (1813), and the War of the Seventh Coalition (1815). The Napoleonic Wars had profound consequences for global and European history, leading to the spread of nationalism and liberalism, the rise of the British Empire as the world's premier power, the independence movements in Latin America and the collapse of the Spanish Empire, the fundamental reorganization of German and Italian territories into larger states, and the establishment of radically new methods in warfare. - Grand Marshal Juan Gregorio de Las Heras ( July 11 , 1780 -- February 15 , 1866 ) was an Argentine soldier who took part in the Spanish American wars of independence and was also a governor of the province of Buenos Aires . - Buenos Aires is the capital and most populous city of Argentina.

American acquisition of Spain's Pacific possessions led to its involvement in the Philippine Revolution and ultimately in the PhilippineAmerican War. - The Spanish American wars of independence were the numerous wars against Spanish rule in Spanish America that took place during the early 19th century, after the French invasion of Spain during Europe's Napoleonic Wars. Although various regions of Spanish America objected to crown policies the restricted trade and privileged Spanish-born officials over American-born, "there was little interest in outright independence; indeed there was widespread support for the Spanish Central Junta formed to lead the resistance against the French." These conflicts started in 1809 with short-lived governing juntas established in Chuquisaca and Quito opposing the composition of the Supreme Central Junta of Seville. When the Central Junta fell to the French invasion, in 1810, numerous new juntas appeared across the Spanish domains in the Americas. The conflicts among these colonies and with Spain eventually resulted in a chain of newly independent countries stretching from Argentina and Chile in the south to Mexico in the north in the first third of the 19th century. Cuba and Puerto Rico remained under Spanish rule until the SpanishAmerican War in 1898. - The Americas, also collectively called America, encompass the totality of the continents of North America and South America.
