After the Fourth Crusade, a new wave of Catholic dioceses, churches and monasteries were founded, a number of different religious orders began spreading into the country, and papal missionaries traversed its territories. Those who were not Catholic in Central and North Albania converted and a great number of Albanian clerics and monks were present in the Dalmatian Catholic institutions. The creation of the Kingdom of Albania in 1272, with links to and influence from Western Europe, meant that a decidedly Catholic political structure had emerged, facilitating the further spread of Catholicism in the Balkans. Durrës became again a Catholic archbishopric in 1272. Other territories of the Kingdom of Albania became Catholic centers as well. Butrint in the south, although dependent on Corfu, became Catholic and remained as such during the 14th century. The bishopric of Vlore also converted immediately following the founding of the Kingdom of Albania. Around 30 Catholic churches and monasteries were built during the rule of Helen of Anjou, as Queen consort of the Serbian Kingdom, in North Albania and in Serbia. New bishoprics were created especially in North Albania, with the help of Helen. As Catholic power in the Balkans expanded with Albania as a stronghold, Catholic structures began appearing as far afield as Skopje (which was a mostly Serbian Orthodoxy city at the time) in 1326, with the election of the local bishop there being presided upon by the Pope himself; in the following year, 1327, Skopje sees a Dominican appointed.
