culture hero
A person, either real or mythical, who embodies or is seen as the foundation of the cultural values or achievements of a society, group of people, or period of time. Karl Marx became both a villain to those opposed to Communist ideology and a culture hero for those who embraced the ideals of Socialism. Mythical figures such as Cúchulainn and historical figures like Brian Boru have long been held as culture heroes in Ireland.
