The historic country in which Soban are found was separated into two countries in what year?
Soban Soban (Hangul: 소반 ; Hanja: 小盤 ) are small tray-like tables, usually wooden, used in Korea for carrying food and as individual dining tables. They are generally made of walnut, pine or ginko wood, often sourced from the carpenter's local area. Carvings and murals showing images of "soban" have been found in tombs dating back to the time of the Goguryeo kingdom. As well as being used for dining, "soban" were also used for general carrying tasks, as writing desks and as small altars for prayers or for burning incense.
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.
