Decolonization

The formation of sovereign states in the New World begins with the United States Declaration of Independence of 1776. The American Revolutionary War lasted until 1783.

The Spanish colonies won their independence in the first quarter of the 19th century, in the Spanish American wars of independence. Simón Bolívar and José de San Martín, among others, led their independence struggle. Although Bolivar attempted to keep the Spanish-speaking parts of the continent politically allied, they rapidly became independent of one another as well, and several further wars were fought, such as the Paraguayan War and the War of the Pacific. (See Latin American integration.) In the Portuguese colony Dom Pedro I (also Pedro IV of Portugal), son of the Portuguese king Dom João VI, proclaimed the country's independence in 1822 and became Brazil's first Emperor. This was peacefully accepted by the crown in Portugal, upon compensation.
