Augsburg Interim participant Charles V
The Augsburg Interim (full formal title: Declaration of His Roman Imperial Majesty on the Observance of Religion Within the Holy Empire Until the Decision of the General Council) was an imperial decree ordered on 15 May 1548 at the 1548 Diet of Augsburg (also having become known as the 'harnessed diet', due to its tense atmosphere, very close to outright hostility) by Charles V, Holy Roman Emperor, who had just defeated the forces of the Protestant Schmalkaldic League in the Schmalkaldic War of 1546/47. Although it ordered Protestants to readopt traditional Catholic beliefs and practices, including the seven Sacraments, it allowed for Protestant clergymen the right to marry and for the laity to receive communion in both kinds (bread and wine). It is considered the first significant step in the process leading to the political and religious legitimization of Protestantism as a valid alternative Christian creed to Roman Catholicism finally realized in the 1552 Peace of Passau and the 1555 Peace of Augsburg. The Interim became Imperial law on 30 June 1548. The Pope advised all bishops to abide by the concessions made to the Protestants in the Interim in August 1549.
