   Independence of Brazil

   The independence of Brazil began after a series of political and military events that led the Kingdom of Brazil to separate from the United Kingdom of Portugal, Brazil and the Algarves. It is celebrated on 7 September, the date in 1822 when prince regent Pedro of Braganza, beside the Ipiranga brook, declared independence from Portugal – a declaration that became known as the Cry of Ipiranga. Formal recognition by Portugal came with the Treaty of Rio de Janeiro, signed in 1825.

   Battle of Ayacucho

   The Battle of Ayacucho was a decisive military encounter during the Peruvian War of Independence. This battle secured the independence of Peru and ensured independence for the rest of belligerent South American states. In Peru, it is considered the end of the Spanish American wars of independence. However, the campaign of Antonio José de Sucre continued through 1825 in Upper Peru, and the siege of the fortresses Chiloé and Callao eventually ended in 1826.
