The island of New Guinea has been populated for tens of thousands of years. European traders began frequenting the region around the late 16th century due to spice trade. In the end, the Dutch Empire emerged as the dominant leader in the spice war, annexing the western part of New Guinea into the colony of Dutch East Indies. The Dutch remained in New Guinea until 1962, even though other parts of the former colony has declared independence as the Republic of Indonesia in 1945. Following negotiations and conflicts with the Indonesian government, the Dutch transferred Western New Guinea to a United Nations Temporary Executive Authority (UNTEA), which was again transferred to Indonesia after the controversial Act of Free Choice. The province was formerly called Irian Jaya and comprised the entire Western New Guinea until the inauguration of the province of West Papua (then West Irian Jaya) in 2001. In 2002, Papua adopted its current name and was granted a special autonomous status under Indonesian legislation.
