Indonesian forces opened fire on student demonstrators protesting the occupation of East Timor in the capital Dili, killing at least 250 people.

The Santa Cruz massacre was the murder of at least 250 East Timorese pro-independence demonstrators in the Santa Cruz cemetery in the capital, Dili, on 12 November 1991, during the Indonesian occupation of East Timor and is part of the East Timor genocide.

The Indonesian occupation of East Timor began in December 1975 and lasted until October 1999. After centuries of Portuguese colonial rule in East Timor, the 1974 Carnation Revolution in Portugal led to the decolonisation of its former colonies, creating instability in East Timor and leaving its future uncertain. After a small-scale civil war, the pro-independence Fretilin declared victory in the capital city of Dili and declared an independent East Timor on 28 November 1975.

Dili is the capital and largest city of Timor-Leste. It lies on the northern coast of the island of Timor, in a small area of flat land hemmed in by mountains. The climate is tropical, with distinct wet and dry seasons. The city has served as the economic hub and chief port of what is now Timor-Leste since its designation as the capital of Portuguese Timor in 1769. It also serves as the capital of the Dili Municipality, which includes some rural subdivisions in addition to the urban ones that make up the city itself. Dili's growing population is relatively youthful, being mostly of working age. The local language is Tetum; however, residents include many internal migrants from other areas of the country.
