Muammar Gaddafi:

The RCC attempted to suppress regional and tribal affiliation, replacing it with a unified pan-Libyan identity. In doing so, they tried discrediting tribal leaders as agents of the old regime, and in August 1971 a Sabha military court tried many of them for counter-revolutionary activity. Long-standing administrative boundaries were re-drawn, crossing tribal boundaries, while pro-revolutionary modernizers replaced traditional leaders, but the communities they served often rejected them. Realizing the failures of the modernizers, Gaddafi created the Arab Socialist Union (ASU), a mass mobilization vanguard party of which he was president. The ASU recognized the RCC as its "Supreme Leading Authority", and was designed to further revolutionary enthusiasm throughout the country.
