The infantry was organized in units of 525 (later 300) men called a "landsfänika" and the cavalry in units of 300 horsemen called a "landsfana". Later on, this was changed to a company—battalion—regiment organization. The system, used and refined by Gustav Vasa and Gustavus Adolphus, was later to be known as the old allotment system. Many people disliked forced conscription, though, and the peasantry in some provinces soon wrote contracts with the state to provide a certain number of soldiers in exchange for being spared from conscription.
