Eric III of Saxe-Lauenburg

Eric III of Saxe-Bergedorf (c. 1335–1401), youngest son of Duke Albert IV of Saxe-Lauenburg and Beata of Schwerin, was initially destined for the clergy. After his brothers John III and Albert V died without heirs he left the church and in 1370 succeeded Albert as duke of the heavily indebted Saxe-Bergedorf-Molln branch.

He pawned Bergedorf, the Vierlande, his half of the Saxon Wood and Geesthacht to Lubeck for 16262.5 marks, keeping only a life tenancy. He died heirless in 1401, succeeded by his cousin Eric IV, under whom the two branch duchies reunited.
