During the early stages of the Scandinavian Viking Age, Ystad in the Danish province Scania and Paviken on Gotland were flourishing centres of trade, but they were not parts of the early Swedish Kingdom. Remains of what is believed to have been a large market dating from 600 to 700 CE have been found in Ystad. In Paviken, an important centre of trade in the Baltic region during the 9th and 10th century, remains have been found of a large Viking Age harbour with shipbuilding yards and handicraft industries. Between 800 and 1000, trade brought an abundance of silver to Gotland, and according to some scholars, the Gotlanders of this era hoarded more silver than the rest of the population of Scandinavia combined.
