What Infantry Regiment helped with the counquest of what is now Indonesia?
Dutch East Indies campaign The Dutch East Indies Campaign of 1941–42 was the conquest of the Dutch East Indies (present-day Indonesia) by forces from the Empire of Japan in the early days of the Pacific Campaign of World War II. Forces from the Allies attempted unsuccessfully to defend the islands. The East Indies were targeted by the Japanese for their rich oil resources which would become a vital asset during the war. The campaign and subsequent three and a half year Japanese occupation was also a major factor in the end of Dutch colonial rule in the region.
Johor Sultanate The Sultanate of Johor (or sometimes Johor-Riau or Johor-Riau-Lingga or Johor Empire) was founded by Malaccan Sultan Mahmud Shah's son, Sultan Alauddin Riayat Shah II in 1528. Johor was part of the Malaccan Sultanate before the Portuguese conquered Malacca's capital in 1511. At its height, the sultanate controlled modern-day Johor, Riau, and territories stretching from the river Klang to the Linggi and Tanjung Tuan, Muar, Batu Pahat, Singapore, Pulau Tinggi and other islands off the east coast of the Malay peninsula, the Karimun islands, the islands of Bintan, Bulang, Lingga and Bunguran, and Bengkalis, Kampar and Siak in Sumatra. During the colonial era, the mainland part was administered by the British, and the insular part by the Dutch, thus breaking up the sultanate into Johor and Riau. In 1946, the British section became part of the Malayan Union. Two years later, it joined the Federation of Malaya and subsequently, the Federation of Malaysia in 1963. In 1949, the Dutch section became part of Indonesia.
