The States of Friesland were the sovereign body that governed the province of Friesland under the Dutch Republic. They were formed in 1580 after the former Lordship of Frisia acceded to the Union of Utrecht and became one of the Seven United Netherlands. The Frisian stadtholder was their "First Servant". The board of Gedeputeerde Staten was the executive of the province when the States were not in session. The States of Friesland were abolished after the Batavian Revolution of 1795 when the Batavian Republic was founded. They were resurrected in name in the form of the Provincial States of Friesland under the Constitution of the Kingdom of the Netherlands.
