November 20

Known in Spain as “20 N,” this observance marks two significant deaths in Spanish history: José Antonio Primo de Rivera in 1936 and Francisco Franco in 1975. Although it is not an official holiday, far-right groups and sympathizers hold rallies and commemorations on this date. Ceremonies often include laying wreaths at memorials, speeches praising their legacies, and gatherings at key historical sites. Over time, the day has become a focal point for debates about Spain’s Civil War past and the Francoist era. Critics view it as glorification of authoritarianism, while supporters see it as honoring national heroes.
