Margaret pursued a centralising policy which inevitably favoured Denmark, because it had a greater population than Norway and Sweden combined. Margaret also granted trade privileges to the Hanseatic merchants of Lübeck in Bergen in return for recognition of her right to rule, and these hurt the Norwegian economy. The Hanseatic merchants formed a state within a state in Bergen for generations. Even worse were the pirates, the "Victual Brothers", who launched three devastating raids on the port (the last in 1427).
