Following its heyday as a world power during the 15th and 16th centuries, Portugal lost much of its wealth and status with the destruction of Lisbon in a 1755 earthquake, occupation during the Napoleonic Wars, and the loss of its Brazilian colony in 1822. A 1910 revolution deposed the monarchy; for most of the next six decades repressive governments ran the country. In 1974, a left-wing military coup installed broad democratic reforms. The following year Portugal granted independence to all of its African colonies. Portugal entered the EC in 1985.
