Indonesia was the colony of which European power?

"Europeans such as the Portuguese arrived in Indonesia from the 16th century seeking to monopolise the sources of valuable nutmeg, cloves, and cubeb pepper in Maluku. In 1602 the Dutch established the Dutch East India Company (VOC) and became the dominant European power by 1610. Following bankruptcy, the VOC was formally dissolved in 1800, and the government of the Netherlands established the Dutch East Indies under government control. By the early 20th century, Dutch dominance extended to the current boundaries. The Japanese invasion and subsequent occupation in 1942–45 during WWII ended Dutch rule, and encouraged the previously suppressed Indonesian independence movement. Two days after the surrender of Japan in August 1945, nationalist leader, Sukarno, declared independence and became president. The Netherlands tried to reestablish its rule, but a bitter armed and diplomatic struggle ended in December 1949, when in the face of international pressure, the Dutch formally recognised Indonesian independence.

An attempted coup in 1965 led to a violent army-led anti-communist purge in which over half a million people were killed. General Suharto politically outmanoeuvred President Sukarno, and became president in March 1968. His New Order administration garnered the favour of the West whose investment in Indonesia was a major factor in the subsequent three decades of substantial economic growth. In the late 1990s, however, Indonesia was the country hardest hit by the East Asian Financial Crisis which led to popular protests and Suharto's resignation on 21 May 1998. The Reformasi era following Suharto's resignation, has led to a strengthening of democratic processes, including a regional autonomy program, the secession of East Timor, and the first direct presidential election in 2004. Political and economic instability, social unrest, corruption, natural disasters, and terrorism have slowed progress. Although relations among different religious and ethnic groups are largely harmonious, acute sectarian discontent and violence remain problems in some areas."
