In 1349, the Black Death spread to Norway and had within a year killed a third of the population. Later plagues reduced the population to half the starting point by 1400. Many communities were entirely wiped out, resulting in an abundance of land, allowing farmers to switch to more animal husbandry. The reduction in taxes weakened the king's position, and many aristocrats lost the basis for their surplus, reducing some to mere farmers. High tithes to church made it increasingly powerful and the archbishop became a member of the Council of State.
