The reign of Thorkall was peaceful. The other three Landmenn were Thorvald in Markland, Thorsteinn in Grønland and Thorfinn Karlsefni (spouse of Freydís, half-sister of Leif Eriksson) in Helluland. Thorkall, as Jarl of Vinland, regined over his uncles. Karlsefni was the first who declared himself King when Thorkall dies (1037). He expanded the Kingdom of Helluland to north and made alliances with the tribes. The dorsetians in north Helluland expanded thei own dominion to south and founded a sort of confederation.
