Despite an inceasingly diverse religious map, Catholicism continues to be the majority religion in Catalonia with more than 83% of the places of worship being Catholic.
During the years of the Franco dictatorship from 1939 to 1975, the link between the Catholic Church and the State was very strong and political and religious power were very closely connected. The State was Catholic and the Church had the monopoly on transmitting religious beliefs and values to society at large.
However, in practice, religion was not restricted to the Catholic Church and even less so in Catalonia.
During the 19th century and the first few decades of the 20th century, Catalonia became a point of reference for Protestantism and there were protestant churches, schools, a hospital and various biblical associations.
In 1918, the Jews opened their first synagogue and later a confessional school, after that, Bahais, Jehovah's Witnesses and millennial churches, such as the Mormons, also opened places of worship.
Buddhists, Hindus, Orthodox Christians and Muslims began opening their own places of worship during the second half of the 20th century and, from the 1990s onwards, with the increase in immigration, Catalonia became even more religiously diverse.
As a result, the link between modernity and secularism was pushed into the background as it became clear that modern Catalonia was increasingly religiously plural.
