Wettin
The House of Wettin is a dynasty which included Saxon kings, prince-electors, dukes, and counts, who once ruled territories in the present-day German federated states of Saxony, Saxony-Anhalt and Thuringia.
The dynasty is one of the oldest in Europe, and its origins can be traced back to the town of Wettin, Saxony-Anhalt. The Wettins gradually rose to power within the Holy Roman Empire. Members of the family became the rulers of several medieval states, starting with the Saxon Eastern March in 1030. Other states they gained were the March of Meissen in 1089, the Landgraviate of Thuringia in 1263, the Palatinate of Saxony in 1350, and the Duchy of Saxe-Wittenberg with the Saxon electoral dignity in 1423.
