Republic of Costa Rica
Who & why: President José María Castro Madriz formally proclaims Costa Rica a republic on 31 August 1848, and on 29 September 1848 adopts a new flag — credited to First Lady Pacifíca Fernández Oreamuno — that keeps the outer blue and white of the old federation banner but inserts a broad central red stripe, consciously echoing the French tricolor's liberty, equality, fraternity. The coat of arms is added to the state flag and revised several times over the following century (notably 1906 and 1964) without altering the stripe pattern. Costa Rica abolishes its standing army in 1948 after a brief civil war and has remained one of the region's most stable democracies since.
What it represents: the blue, white, red, white, blue flag whose current design was created on 29 September 1848 at the suggestion of Pacífica Fernández Oreamuno, wife of President José María Castro Madriz, who proposed adding the red stripe; its colours are linked to the ideals of the 1848 French Revolution (freedom, equality, brotherhood). The state flag with the coat of arms was adopted on 27 November 1906 and the arms were altered on 21 October 1964; FOTW says the 1964 law requires the official flag to bear the arms.
