Helmet of Gustav I (supports 3D printing)
King of Sweden (1496-1560). Born into a noble family, he took part in the struggle against Danish rule in 1517. After losing the war in 1518, he was taken to Denmark as a hostage and fled back the following year. In November 1520, the Danes created the "Stockholm murder" in Sweden, killing about 100 Swedish nobles, priests and citizens, which became the fuse of the Swedish independence movement. He led a popular uprising in Dalarna County in 1521, defeated the Danish occupation forces in 1523, was elected king, and established the Vasa Dynasty.
