Upon his ascension to the papacy, Pius V immediately faced the task of enacting the reforms of the Council of Trent. New seminaries were opened, a new breviary, new missal, and new catechism were published; foundations were established to spread the Faith and preserve the doctrine of the Church. Pius spent much time personally working with the needy. He built hospitals and used the papal treasury to care for the poor. Pius faced many difficulties in the public forum, both in the implementation of the Tridentine reforms and in interaction with other heads of state. At the time of his death he was working on a Christian European alliance to break the power of the Islamic states.
