 Their recent failures and the threat of Wenceslaus II prompted Przemysł II and Władysław, the existing Polish competitors for the throne of Kraków, to meet in Kalisz in January 1293 in order to develop strategies for removing the Czech government.The reconciliation of the opponents occurred as a result of the intervention of Archbishop Jakub Swinka; for his part the archbishop was promised the revenues from the salt mines after Lesser Poland was won.The secret agreement, signed 6 January 1293, committed the three princes (the arrangement was also attended by Casimir II of Łęczyca) to mutual support in the effort to recover Krakow.
