The Assembly of the Martian Colonies was the ruling body of the Martian Colonies. It was in existence following the Fundamental Declarations of the Martian Colonies and continued to function by the mid-22nd century. The Assembly was described as not being a dictatorship and was linked closely with the tribal groups such as the Martian Hopi-Pueblo nation. In 2155, the Assembly was involved in the Coalition Compact crisis that involved the aggressive actions of the Romulan Star Empire. (ENT novel: Beneath the Raptor's Wing)
