Pope Martin IV
Świnka was consecrated as archbishop in Kalisz on 30 July 1283 and the results of the voting were accepted by Pope Martin IV on 19 December the same year. The election of a Polish archbishop was seen by the rulers of Greater Poland as a chance to break the links with the Holy Roman Empire, and on 1 August 1284 Duke Przemysł II granted the bishops of Gniezno with a privilege to mint their own coins. This strengthened their power significantly.
