John IV of Dražice
John IV of Dražice (c. 1260–1343) was Bishop of Prague from 1301 until his death. A Prague canon from a noble Bohemian family, in 1310 he backed John of Luxembourg's seizure of the Bohemian crown with troops and money.
In 1318 Pope John XXII suspended him on Dominican charges; he spent eleven years at Avignon before being restored in 1329. He then became a lavish builder, founding an Augustinian monastery and a stone bridge over the Elbe at Roudnice nad Labem, and died in 1343, buried at St Vitus.
