Frederick III, Margrave of Meissen

Frederick III the Strict (1332–1381) of the House of Wettin was Margrave of Meissen and Landgrave of Thuringia. Born at Dresden, he took over the government after his father Frederick II died in 1349, initially ruling on behalf of his brothers William, Balthasar and Louis; from 1368 the brothers ruled jointly, exercising authority in two-year rotations, and in 1379 their lands were permanently divided.

He married Catherine of Henneberg, heiress to Coburg and other estates, and his son by her became Elector Frederick I of Saxony. Frederick died at Altenburg in 1381.
