Onn Jaafar

Dato' Sir Onn bin Dato' Jaafar (Jawi: عون بن جعفر; 12 February 1895 – 19 January 1962) was a Malayan politician who served as the 7th Menteri Besar of Johor from 1947 to 1950, then Malaya (now Malaysia). His organised opposition towards the creation of the Malayan Union (by the returning British colonial power after the end of the Japanese occupation of Malaya) led him to form the United Malays National Organisation (UMNO) in 1946; he was UMNO's founder and its first President until his resignation in 1951. He was famously known as the pioneer of organised anti-imperialism and early Malay nationalism within the entire Malaya, which eventually culminated with the Malayan independence from Britain. He was also responsible for the social and economic welfare of the Malays by setting up the Rural Industrial Development Authority (RIDA).

His son is Hussein Onn, the third and former Prime Minister of Malaysia, his grandson is the senior UMNO politician, Hishammuddin Hussein, and his great-grandson is Onn Hafiz Ghazi, the current Member of the Johor State Legislative Assembly for Layang-Layang and 19th Menteri Besar of Johor.
