Wenceslas II was born on September 27, 1271 in Prague as the long-awaited son and heir of the Czech King Přemysl Otakar II. and his second wife Kunhuta. In the battle of the Moravian Field in 1278 with the army of Rudolf Habsburg, his father King Přemysl Otakar II. fell.
Guardianship over Wenceslas (and the government in Bohemia) was acquired for five years by the Margrave of Brandenburg, Otto IV. Brandenburg.
King Wenceslas II returned to Bohemia in May 1283. The first of Wenceslas' goals after taking over the power was to calm the situation in the kingdom.
Around 1295, the last royal town in the West Bohemian region Nová Plzeň was founded on "green turf". Wenceslas' coronation took place on June 2, 1297 in Prague.
In 1298 Wenceslas II. accepted the offer to take over as the ruler of the Polish kingdom. In May 1301, the Hungarian magnates decided to declare the son of the Czech King Wenceslas III to be the waiter of the St.
Stephen's Crown. In the spring of 1304, Václav, at that time already suffering from advanced tuberculosis, set out at the head of the army to Hungary to help his son.
The war ended after Kutná Hora defended itself against the army of Rudolf Habsburg and his allies, and the retreat of the enemy troops turned into a confused escape. Wenceslas II he last exhaled in Prague on June 21, 1305.
