Saint George is the patron saint of England in a tradition established in the Tudor period, based in the saint's popularity during the times of the Crusades and the Hundred Years' War. Veneration of the saint in folk religion declined in the 18th century, but attempts to revive celebration of Saint George's Day (23 April) as an expression of English culture and identity go back to the foundation Royal Society of St. George in 1894 and have more recently, since the beginning 2010s, resulted in Saint George's Day celebrations with aspects of a national holiday in England.
