During the Protestant Reformation, the popular tracts and catechisms of Martin Luther, John Calvin and other Reformers were sold in areas controlled by Protestant monarchs, who determined the faith in their region, Cuius regio, ejus religio. Catholic Catechisms, published by individuals existed as well. The Jesuit Petrus Canisius had published such a Catechism in 1555 in both German and Latin language. The Council of Trent commissioned the first Church-wide Roman Catholic catechism. This catechism was directed to clergy. It included large parts of the Canisius catechisms including his addition to the Hail Mary: Holy Mary, Mother of God, pray for us sinners.
