 The terms of the treaty were unacceptable to the Patriarch of Jerusalem Gerald of Lausanne, who placed the city under interdict.In March, Frederick crowned himself in the Church of the Holy Sepulchre, but because of his excommunication and the interdict Jerusalem was never truly reincorporated into the kingdom, which continued to be ruled from Acre.Meanwhile, in Italy, the Pope had used Frederick's excommunication as an excuse to invade his Italian territories; the papal armies were led by Frederick's former father-in-law John of Brienne.
