In 1558, the Transylvanian Diet's Edict of Torda declared free practice of both Catholicism and Lutheranism. Calvinism, however, was prohibited. Calvinism was included among the accepted religions in 1564. Ten years after the first law, in 1568, the same Diet, under the chairmanship of King of Hungary, and Prince of Transylvania John Sigismund Zápolya (John II.), following the teaching of Ferenc Dávid, the founder of the Unitarian Church of Transylvania, extended the freedom to all religions, declaring that ""It is not allowed to anybody to intimidate anybody with captivity or expelling for his religion"". However, it was more than a religious tolerance; it declared the equality of the religions, prohibiting all kinds of acts from authorities or from simple people, which could harm other groups or people because of their religious beliefs. The emergence in social hierarchy wasn't dependent on the religion of the person thus Transylvania had also Catholic and Protestant monarchs, who all respected the Edict of Torda. The lack of state religion was unique for centuries in Europe. Therefore, the Edict of Torda is considered as the first legal guarantee of religious freedom in Christian Europe.
