For four centuries, the Catholic Albanians defended their faith, aided by Franciscan missionaries, beginning in the middle of the 17th century, when persecution by Ottoman Turkish lords in Albania started to result in the conversion of many villages to the Islamic faith. The College of Propaganda at Rome played a significant role in the religious and moral support of the Albanian Catholics. During the 17th and 18th centuries, the College contributed in educating young clerics appointed to service on Albanian missions, as well as to the financial support of the churches. Work was done by the Austrian Government at the time, which offered significant financial aid in its role as Protector of the Christian community under Ottoman rule.

A seminary, founded in 1858 by Archbishop Topich of Scutari, was destroyed by the Ottomans, but was later re-established on Austrian territory and placed under imperial protection. Eastern Orthodoxy According to the 2011 Census, 6.75% of the Albanian population adhere to the Albanian Orthodox Church.
