PROBLEM: Passage: The East Timorese rebellion of 1911-12, sometimes called the Great Rebellion or Rebellion of Manufahi, was a response to the efforts of Portuguese colonial authorities to collect a head tax and enforce the corvée, part of their larger effort to encourage cash crop agriculture and construct modern infrastructure. The countrywide conflict of 1911-12 was the culmination of a series of revolts led by Dom Boaventura, the liurai  of the native kingdom of Manufahi. The first lasted from 1894 to 1901, the second from 1907 to 1908. In 1911 Boaventura led an alliance of local kingdoms in the last and most serious revolt against the Portuguese. In February 1912 rebels from one kingdom entered the colonial capital of Dili, killing and burning as they went. They looted Government House and decapitated several Portuguese soldiers and officers. In August, the Portuguese brought in troops from Mozambique and a gunboat from Macau to suppress the revolt. The revolt cost 3,424 Timorese killed and 12,567 wounded, and 289 Portuguese killed and 600 wounded. After 1912 the Portuguese pacification of East Timor was complete. They also ceased to appoint hereditary liurais and the native states went extinct. The rebellion of 1912 was seminal in creating an East Timorese identity distinct from "Portuguese subject" or just "Timorese".
Question: Who were entered the colonial capital of Dili?

PROBLEM: Passage: The First Utrecht Civil War  took place between 1470 and 1474 when the Hook and Cod wars spilled over into the Bishopric of Utrecht. David of Burgundy, illegitimate son of Philip the Good, Duke of Burgundy had been  appointed as bishop of Utrecht in 1456 with support of the Cods. The Utrecht chapters, however, had elected the Hook-favoured provost Gijsbrecht van Brederode as bishop. But Philip the Good used force to make David's appointment be accepted. Nevertheless, opposition against his rule remained, and David of Burgundy even found it safer to leave the city of Utrecht and take up residence in Wijk bij Duurstede. The van Brederode family was at the center of the opposition. In 1470, David of Burgundy imprisoned Gijsbrecht van Brederode and his brother Reinoud II van Brederode, and had them tortured. This action stirred up the century old animosity between the Hooks who supported the family van Brederode and the Cods who supported Burgundy. A civil war broke out that lasted until 1474.The status-quo returned, until a Second Utrecht Civil War broke out in 1481.
