Omar Ali Saifuddien III

Omar Ali Saifuddien Sa'adul Khairi Waddien (Jawi: عمر علي سيف الدين سعد الخير والدين‎; 23 September 1914 – 7 September 1986) was the 28th Sultan of Brunei, reigning from 1950 until his abdication in 1967 to his oldest son, Hassanal Bolkiah.

Over the course of his 17-year reign, Sultan Omar Ali Saifuddien III significantly altered Brunei. He also created the Melayu Islam Beraja (MIB) philosophy, which is the country's guiding ideology. In order to prepare his people for the restoration of the state's sovereign rights—which had been started by his predecessor and spurred by the Brunei nationalist movement toward the close of World War II—he also started social and economic reform. He became known as the Architect of Modern Brunei, Royal Poet, Father of Brunei Negara Zikir and Father of Independence.
