The priests refused and did not accuse him of anything but Dolcino was terrorized and fled far away to the city of Trento where he met and joined the sect of the Apostolics. Dolcino left Vercelli between 1280 and 1290 and the researches of Orioli show that in the same period the fights between Guelphs and Ghibellines caused many victims on both sides in the city; the fear of being involved in these fights could better explain his decision to leave and join the initially pacifist movement of Segarelli. The inquisitor Bernardo Gui cites the same episode, concluding that he fled to Trento to escape the just punishment for his burglaries. Fra Dolcino, a former member, became in 1300 the leader of the movement of Apostolics, and influenced by the millenarist theories of Gioacchino da Fiore gave birth to the Dulcinian movement, which existed between the years 1300 and 1307. It ended in the mountains in Sesia Valley and in the Biella area, in Piedmont, Italy, on 23 March 1307 when many crusaders (multi crucesignati) finally conquered the fortification built on the mount Rubello by the Dulcinians. According to the Roman Catholic Church and most historians of the period, Dolcino and his followers, in reaction to attacks by Catholic troops, became criminals (today they would probably be called guerrilla fighters), who would not hesitate, for their own survival, to plunder and devastate villages, killing any who opposed them, and burning their houses. He justified the actions committed by his followers in this period citing Saint Paul (Epistle to Titus 1:15): "To the pure all things are pure, but to the corrupt and unbelieving nothing is pure; their very minds and consciences are corrupted", as reported by the Anonymous Synchronous Dolcino maintained: "[...] that it was legitimate for him and his followers to hang, behead, [...] people who obey to the Roman church and burn down, destroy, [...] because they were acting to redeem them and thus without sin". Despite this, he was considered by some to be one of the reformers of the Church and one of the founders of the ideals of the French revolution and socialism. In particular he was positively reevaluated toward the end of the 19th century and was dubbed the Apostle of the Socialist Jesus and thus in 1907 left wing workers of Biella and the Sesia Valley erected a monument on mount Rubello,<ref>{{Cite book
