The First Brazilian Republic or República Velha (Portuguese pronunciation: [ʁeˈpublikɐ ˈvɛʎɐ], "Old Republic") is the period of Brazilian history from 1889 to 1930. The República Velha ended in 1930 with a military coup, also known as Brazilian Revolution of 1930 that installed Getúlio Vargas as a dictator.
