The main religion practiced in Spain is Roman Catholicism, which has deep historical roots in the country. Over 60% of the Spanish population identifies as Catholic, and the religion significantly influences cultural traditions, festivals, and social life. Major events such as Semana Santa (Holy Week) and numerous local fiestas celebrate Catholic saints and religious history. However, Spain has also witnessed a rise in secularism and a diversity of beliefs, including Protestantism, Islam, and other faiths. The coexistence of these beliefs reflects Spain's evolving social landscape and cultural richness.
