Christianity in Spain has a rich history, primarily influenced by the Roman Catholic Church. It became the dominant religion after the Visigothic conversion in the early 7th century. The Reconquista, a series of campaigns to reclaim the Iberian Peninsula from Muslim rule, further solidified Catholicism's role in Spanish identity. Today, Spain remains predominantly Roman Catholic, although there is a growing presence of other Christian denominations and secular beliefs. Major religious events, such as Semana Santa (Holy Week) and Christmas, are widely celebrated, reflecting the deep cultural ties between Christianity and Spanish traditions.
