After the 1910 revolution deposed the monarchy, the democratic but unstable Portuguese First Republic was established, later being superseded by the "Estado Novo" authoritarian regime. Democracy was restored after the Carnation Revolution (1974), ending the Portuguese Colonial War. Shortly after, independence was granted to almost all its overseas territories. The handover of Macau to China (1999) marked the end of what can be considered one of the longest-lived colonial empires in history.
