Isabel Barreto Lobato

Her husband, deposed Prime Minister Nicolau dos Reis Lobato, managed to escape to the interior mountains at the start of the invasion. Lobato helped wage a guerrilla war against the Indonesian occupation, until he was killed in 1978 by Indonesian forces led by Lieutenant Prabowo Subianto.

Isabel Barreto Lobato (1948 – 8 December 1975) was an East Timorese politician, political activist, and member of Fretilin who was active in the movement for independence from Portugal. Barreto Lobato was a leading member of the Fretilin Women's Association at the time of East Timor's declaration of independence in November 1975. She was the wife of East Timor's first prime minister, Nicolau dos Reis Lobato, who held the office for nine days before the Indonesian invasion and occupation.

On 7 December 1975, Indonesia invaded East Timor shortly after the country declared independence from Portugal. Isabel Barreto Lobato and other members of Fretilin's political leadership were captured by Indonesian troops. The next morning, December 8th, Barreto Lobato and her colleagues were taken to Dili's waterfront wharf where they were shot by Indonesian forces and thrown into the harbor. Other individuals killed with Barreto Lobato during the mass execution included Rosa Bonaparte, Bernardino Bonaparte, and Francisco Borja da Costa, the composer of East Timor's national anthem.

Barreto Lobato was born in the village of Bazartete, Portuguese Timor, in 1948. She married Nicolau dos Reis Lobato in a Catholic wedding ceremony at a chapel in Bazartete in 1972. The couple had one son, José Maria Barreto Lobato.
