 But the intransigeance of the Count of Chambord, who refused to abandon the white flag and its fleur-de-lis against the republican tricolore, and the 16 May 1877 crisis forced the legitimists to abandon the political arena, while some of the more liberal Orléanists "rallied" throughout years to the Third Republic (1870–1945).However, since the monarchy and Catholicism were long entangled ("the alliance of the Throne and the Altar"), republican ideas were often tinged with anti-clericalism, which led to some turmoil during Radical Émile Combes' cabinet in the beginning of the 20th century.Concerns about monarchists causes the French government to bury the Unknown Soldier of World War I at the Arc de Triomphe, because the Panthéon was associated with the Republic.
