Bergedorf () is the largest of the seven boroughs of Hamburg, Germany, named after Bergedorf quarter within this borough. In 2020 the population of the borough was 130,994. History The city of Bergedorf received town privileges in 1275, then a part of the younger Duchy of Saxony (1180–1296), which was partitioned by its four co-ruling dukes in 1296 into the branch duchies of Saxe-Lauenburg and Saxe-Wittenberg. Bergedorf then became part of the former. This was only to last until 1303, when Lauenburg's three co-ruling dukes, Albert III, Eric I, and John II partitioned their branch duchy into three smaller duchies. Eric then held Bergedorf (Vierlande) and Lauenburg and inherited the share of his childless brother Albert III, Saxe-Ratzeburg, after he was already deceased in 1308 and a retained section from Albert's widow Margaret of Brandenburg-Salzwedel on her death. However, his other brother, John II, then claimed a part, so in 1321 Eric conceded Bergedorf (with Vierlande) to him, whose share thus became known thereafter as Saxe-Bergedorf-Mölln while Eric's was known as Saxe-Ratzeburg-Lauenburg. In 1370, John's fourth successor Eric III pawned the Herrschaft of Bergedorf, the Vierlande, half the Saxon Wood and Geesthacht to Lübeck in return for a credit of 16,262.5 Lübeck marks. This acquisition included much of the trade route between Hamburg and Lübeck, thus providing a safe passage for freight between the cities. Eric III only retained a life tenancy. The city of Lübeck and Eric III further stipulated, that upon his death, Lübeck would be entitled to take possession of the pawned areas until his successors repaid the credit and simultaneously exercised the repurchase of Mölln (contracted in 1359), altogether amounting to the then enormous sum of 26,000 Lübeck Marks. In 1401, Eric III died without issue and was succeeded by his second cousin Eric IV of Saxe-Ratzeburg-Lauenburg. In the same year, Eric IV, supported by his sons Eric (later ruling as Eric V) and John, forcefully captured the pawned areas without making any repayment, before Lübeck could take possession of them. Lübeck acquiesced for the time being. In 1420, Eric V attacked Prince-Elector Frederick I of Brandenburg and Lübeck allied with Hamburg in support of Brandenburg. Armies of both cities opened a second front and conquered Bergedorf, Riepenburg castle and the Esslingen river toll station (today's Zollenspieker Ferry) within weeks. This forced Eric V to agree with Hamburg's burgomaster Hein Hoyer and Burgomaster Jordan Pleskow of
