An agreement between Catholics and Lutherans of Germany that recognizes imperial the confession of Augsburg (1530) as well as the Catholic faith. Incarnated in a decree issued on 25 September 1555 at the Reichstag of Augsburg, it definitively recorded the failure of Emperor Charles v`s efforts to repair Germany`s broken religious unity (see intercessions). The emperor`s military pacification of Germany was destroyed by the political ambitions of the princes who, in 1552 under Mauritius of Saxony, went into rebellion. This second cold war led to the defeat of Charles V by Maurice, supported by his French allies (see schmalkaldic league). Charles`s failure to win back Metz after his contract with Maurice ended his discouragement. Karl instructed his brother Ferdinand (then Emperor Ferdinand I) to lead the negotiations that settled a political settlement of religious disputes. The treaty provided that the religion of the sovereign would determine whether a state should be exclusively Catholic or Lutheran. In the more than eighty “cities of the Reich” of the Holy Roman Empire (cities that owed political obedience to the emperor only), the two religions – Lutheranism and Catholicism – should be tolerated. Luther`s right to church property, which they had acquired before 1552, was also maintained. A private statement by Ferdinand recognized religious freedom on certain subjects of religious princes. The ecclesiastical princes, who became Protestants, were forced to resign from their lakes after a clause inserted by Ferdinand. The conversion of several high-ranking princes to Calvinism in the 1560s and 1570s weighed on the conditions of peace, as the treaty recognized only Lutheran and Catholicism as legal religions. Despite these and other challenges, the treaty`s solution to the imperial religious crisis was long and continued until the outbreak of the Thirty Years` War in 1618.
The treaty, which ended this conflict in 1648 – the peace of Westphalia – granted legal recognition to Calvinism within the Empire, but on most other points it only repeated many of the compromises first drafted in the peace of Augsburg. The ecclesiastical lands, occupied by Lutheran rulers by Catholic prelates who were not the emperor`s immediate vassals, were to remain with the Lutherans, though continuous goods could be proven since the time of the Treaty of Passau (August 2, 1552). However, in order to ensure the permanence of the remaining ecclesial territories, Catholics were provided that, in the future, any ecclesiastical prince who became a Protestant would renounce his ministry, his country and his income. Since Lutherans did not accept this ecclesiastical reservation and Catholics did not give in, Ferdinand added the clause under his own responsibility, stating that no agreement had been reached on the matter. In fact, Lutherans have been able, in many cases, to null and void their effects. In June 1546, Pope Paul III reached an agreement with Emperor Charles V in the Roman Holy Roman to stem the spread of the Reformation. In this agreement, it was said in part: In addition to the end of the open war between the belligerents The peace of Westphalia established several important principles and agreements: the interim of Augsburg (“The Declaration of His Roman Imperial Majesty on the Respect of Religion in the Holy Empire until the decision of the General Council”) was an imperial decree, Ordained on 15 May 1548 at the Reichstag of Augsburg by Charles V, the emperor of the Holy Roman Empire, who had just defeated the troops of the Protestant Confederacy of La Caledian in the War of La Caledian of 1546/47. Although it ordered Protestants to resume traditional Catholic beliefs and practices, including the seven sacraments, it allowed Protestant clerics to marry and receive communion in both genres (bread and wine) to the laity.  It is considered the first important step in the process that leads to the political and religious legitimization of Protestantism as an alternative profession of Christian faith to Catholicism, finally carried out in 1552 in the peace of Passau and in 1555 in the peace of Augsburg.
