Vaughan Gething won the Welsh Labour Party leadership contest on Saturday by securing 51.7% of the vote and will become the first Black leader of the semi-autonomous government.
"Today, we turn a page in the book of our nation's history. A history we write together," Gething said after he won the election.
Gething will replace Mark Drakeford, who is expected to resign on March 19, with the Welsh parliament formally set to elect the next leader the following day.
After British Prime Minister Rishi Sunak and Scottish First Minister Humza Haroon Yousaf, Gething is the third leader who is a son of an immigrant in the UK.
Gething was born in Zambia to a Welsh father and a Zambian mother, Sunak has Indian heritage, while Yousaf was born to a Pakistani family in the UK.
