Dili, spelled Díli in Portuguese, is the capital and largest city of East Timor. It lies on the northern coast of Timor island, the easternmost of the Lesser Sunda Islands. Dili is the chief port and commercial centre for East Timor, and has approximately 150,000 inhabitants. There is also an airport in Comoro, Presidente Nicolau Lobato International Airport, renamed after independence leader Nicolau Lobato, which is used for commercial and military flights.

Dili was settled about 1520 by the Portuguese, who made it the capital of Portuguese Timor in 1769. During World War II, Dili was occupied by the Japanese. East Timor unilaterally declared independence from Portugal on November 28, 1975. However, nine days later, on December 7, Indonesian forces invaded Dili. On July 17, 1976, Indonesia annexed East Timor, which it designated the 27th province of Indonesia, Timor Timur, with Dili as its capital.

A guerrilla war ensued from 1975 to 1999 between Indonesian and pro-independence forces, during which tens of thousands of East Timor's and some foreign civilians were killed. Media coverage of the 1991 Dili Massacre helped revitalise international support for the East Timorese independence movement. In 1999, East Timor was placed under UN supervision and on May 20, 2002, Dili became the capital of the newly independent Democratic Republic of Timor-Leste. In May 2006, fighting and rioting sparked by conflict between elements of the military caused significant damage to the city and led to foreign military intervention to restore order.
