By 1973 the PAIGC controlled most of the interior of the country, while the coastal and estuary towns, including the main populational and economic centres remained under Portuguese control. The village of Madina do Boé in the southeasternmost area of the territory, close to the border with neighbouring Guinea, was the location where PAIGC guerrillas declared the independence of Guinea-Bissau on September 24, 1973. The war in the colonies was increasingly unpopular in Portugal itself as the people got weary of war and balked at its ever-rising expense. Following the coup d'état in Portugal in 1974, the new left-wing revolutionary government of Portugal began to negotiate with the PAIGC and decided to offer independence to all the overseas territories.
