The planet was governed by a representative government. The legislative body was known as the Acamarian Ruling Council. This government was headed by a Sovereign. In 2366, the sovereign was Marouk. The Acamarian Internal Security was responsible for law enforcement duties.
That same year, the USS Enterprise-D enlisted the aid of Sovereign Marouk to end the Gatherer raids on Federation outposts. Upon completion of this mission, the Enterprise returned the sovereign to her planet. (TNG: "The Vengeance Factor")
