Nicaragua’s flag (4 September 1908) is a blue‑white‑blue triband with the coat of arms centred: a triangle with five volcanoes between two oceans beneath a rainbow and Phrygian cap, encircled by “República de Nicaragua – América Central.” The colours recall the federation; statutes set a 3:5 ratio, colour standards, armorial drawings, and usage; civil flags omit arms.
Nicaragua’s flag, reinstated on 4 September 1908, restores the Central American triband while adopting a national coat of arms that affirms both state and regional identity. The blue stripes reference the Caribbean and Pacific and ideals of justice and loyalty; the white centre stands for peace.
The arms reprise the iconography of the United Provinces: an equilateral triangle for equality; five volcanoes rising between two oceans, signifying the five historic republics; a red Phrygian cap for liberty; a rainbow for peace; and solar rays. The circular legend binds the emblem to Central America. Later standardisations—most notably in 1971—clarified drawings and colour tones.
Law distinguishes the state flag (with arms) from the civil flag (without), prescribes a 3:5 proportion, and regulates manufacture and contexts of use. Protocol covers precedence, half‑masting by decree, and dignified retirement. Public buildings and schools raise the flag on national dates, especially 15 September, while abroad the banner signals sovereignty at embassies and multilateral institutions.
Through revolutions, occupations, and political reconfiguration, the flag’s essential scheme has endured with only heraldic refinements, providing a stable visual anchor for Nicaraguan civic life and diaspora communities.
