Gustavus (I.) Vasa or Gustavus Ericssen, king of Sweden from 1523 to 1560, born at Lindholm, in Upland; having conceived the idea of freeing his country from the yoke of Denmark, under which it had fallen in 1519, and his early efforts to infuse a spirit of patriotic rebellion into the Swedes proving ineffectual, he was captured by the Danes; escaping from captivity, he became a wanderer in his own land, working in mines and enduring great privations, but at last, in 1520, the Swedes were goaded to rebellion, and under him eventually drove the Danes from their land in 1523; during his long reign Gustavus gradually brought his at first disorganised empire into a peaceful and united realm (1496-1560).
