 The meeting was occasioned by the revolution in Rome, which had deposed Pope Pius IX from his position as head of the Papal States and seen him flee from the city in disguise to a refuge in Neapolitan territory.The meeting was, in fact, sanctioned by Pope Pius.In a bull of 17 March 1726, Pescia was established as a diocese by Pope Benedict XIII, and was for a long time immediately subject to the Holy See (Papacy).
