In 1975, the Carnation Revolution in Portugal caused authorities there to announce plans for decolonisation of Portuguese Timor, the eastern half of the island of Timor whose western half was a part of the Indonesian province of East Nusa Tenggara. In the East Timorese elections held in 1975, Fretilin, a left-leaning party, and UDT, aligned with the local elite, emerged as the largest parties, having previously formed an alliance to campaign for independence from Portugal. Apodeti, a party advocating integration with Indonesia, enjoyed little popular support.
