Patronages of the Immaculate Conception the Immaculate Conception is also one of the nine national and public holidays and a holy day of obligation. The patronage settles the dispute between a heated religious debate during the mid 1600s, when followers of the mythical figure Saint James Matamoros wished to impose him as the national patron saint versus the followers of Saint Teresa of Avila. On 11 September 1759, the elected members of the Spanish Cortes petitioned King Charles III of Spain to request from the pope the "universal patronage of Our Lady of the Immaculate Conception in all the Kingdoms of Spain and the Indies".
Saint James Matamoros says: "While this event is based on legend, the supposed battle has provided one of the strongest ideological icons in the Spanish national identity." In the 17th century, followers of his cult ("Santiaguistas") proposed the patronage of Spain under his name, in contrast to those who favored Teresa of Ávila. The "Santiaguistas" overcame and won this religious debate, naming him the Patron Saint of Spain, until November 1760 when Pope Clement XIII rescinded this honor and officially declared the Immaculate Conception as the patroness of Spain as a country, and installed the historical apostle James as patron of the Spaniards.
