Ahdut HaAvoda was the name used by a series of political parties. Ahdut HaAvoda in its first incarnation was led by David Ben-Gurion. It was first established during the period of British Mandate and later became part of the Israeli political establishment. It was one of the forerunners of the modern-day Israeli Labor Party.

David Ben-Gurion was the primary national founder of the State of Israel as well as its first prime minister. As head of the Jewish Agency from 1935, and later president of the Jewish Agency Executive, he was the de facto leader of the Jewish community in Palestine, and largely led the movement for an independent Jewish state in Mandatory Palestine.
