Yang Di-Pertuan Besar
Tuanku Ja’afar was to have left for Japan to serve as the Malaysian Ambassador to that country but was recalled by the State Government of Negeri Sembilan following the demise of his half brother HRH Tuanku Munawir, the then ruler of Negeri Sembilan, in 1967.
All four Undang (Territorial Chiefs) had unanimously elected Tuanku Ja’afar as the Yang di-Pertuan Besar of Negeri Sembilan to succeed HRH Tuanku Munawir. The election was controversial as the heir presumptive to the throne, Tuanku Munawir's son Tunku Muhriz was by-passed. It has been suggested that the then Prime Minister of Malaysia, Tunku Abdul Rahman, instructed the council not to choose Tunku Muhriz on account of his youth (he was then eighteen).
Tuanku Ja’afar ascended the throne as the 10th Ruler of Negeri Sembilan on 18 April 1967.
