Otumfuo Opoku Ware II (born Jacob Matthew Poku, 30 November 1919 – 26 February 1999) was the 15th Asantehene. He succeeded his uncle Osei Tutu Agyeman Prempeh II in 1970 and ruled for 29 years until his death in February 1999. He was succeeded by Otumfuo Nana Osei Tutu II.
The future monarch was born under the name Jacob Matthew Poku in Kumasi the capital of Ashanti, then the Ashanti Protectorate, in 1919 into the Ashanti royal family. At the time, Prempeh I was Asantehene, as the Ashanti Emperor-King is called, before being succeeded by his nephew Prempeh II in 1931. Prempeh II in turn was Opoku Ware II’s uncle, making the boy one of several candidates to succeed him, as to be decided by the Queen-mother, or Nana Asantehemaa. After attending Anglican school, Poku went to Adisadel College in Cape Coast. After working in the public sector for a while, in the 1950s, he moved to the United Kingdom to study law at the Middle Temple and was admitted to the bar in 1962.
