It existed from the 12th century until 1918, when it became part of the Free State of Mecklenburg-Vorpommern. The capital city was Schwerin, known for its picturesque lakes and the impressive Schwerin Castle. The state was ruled by the Dukes of Mecklenburg-Schwerin, who played a significant role in the region's history. The economy was primarily based on agriculture, with a focus on grain and livestock.
