Palau, officially the Republic of Palau and historically Belau, Palaos or Pelew, is an island country and microstate in the western Pacific. The republic consists of approximately 340 islands and connects the western chain of the Caroline Islands with parts of the Federated States of Micronesia. It has a total area of 466 km2. The most populous island is Koror, home to the country's most populous city of the same name. The capital Ngerulmud is located on the nearby island of Babeldaob, in Melekeok State. Palau shares maritime boundaries with international waters to the north, the Federated States of Micronesia to the east, Indonesia to the south, and the Philippines to the northwest.

The country was originally settled approximately 3,000 years ago by migrants from Maritime Southeast Asia. Palau was first drawn on a European map by the German missionary Paul Klein based on a description given by a group of Palauans shipwrecked on the Philippine coast on Samar. Palau islands were made part of the Spanish East Indies in 1885. Following Spain's defeat in the Spanish–American War in 1898, the islands were sold to Germany in 1899 under the terms of the German–Spanish Treaty, where they were administered as part of German New Guinea. After World War I, the islands were made a part of the Japanese-ruled South Seas Mandate by the League of Nations. During World War II, skirmishes, including the major Battle of Peleliu, were fought between American and Japanese troops as part of the Mariana and Palau Islands campaign. Along with other Pacific Islands, Palau was made a part of the United States-governed Trust Territory of the Pacific Islands in 1947. Having voted in a referendum against joining the Federated States of Micronesia in 1978, the islands gained full sovereignty in 1994 under a Compact of Free Association with the United States.
