 The "standstill" required the Protestants to continue to take part in the Imperial wars against the Turks and the French, and postponed religious affairs until an ecumenical council of the Catholic Church was called by the Pope to solve the issue.Due to Papal delays in organizing a general council, Charles V decided to organize a German summit and presided over the "Regensburg talks" between Catholics and Lutherans in 1541, but no compromise was achieved.In 1545, the Council of Trent was finally opened and the Counter-Reformation began.
