Croatia’s flag displays red, white, and blue horizontal bands with the distinctive šahovnica (checkerboard) coat of arms centered and a crown of five smaller shields above. Adopted on 21 December 1990 as the socialist emblem was removed, the design draws on the 1848 Pan‑Slavic palette and Croatia’s historic regions. Law fixes proportions and usage, with the civil, state, and military standards differentiated by heraldic details.
Croatia’s national flag—red, white, and blue stripes bearing the central šahovnica (checkerboard) shield—integrates Pan-Slavic colours with a heraldic motif that has represented Croatian lands for centuries. Adopted shortly before international recognition of independence, the flag’s present form dates to 21 December 1990 and reflects a conscious departure from Yugoslav socialist emblems.
The tricolour arrangement has roots in the 1848 revolutionary period, when movements across the Habsburg realms advocated national rights and constitutional reforms. Croatian banners adopted red, white, and blue—colours resonant with the wider Slavic palette and visible in the heraldry of Croatia, Slavonia, and Dalmatia. Through the later nineteenth century and into the twentieth, these stripes served as markers of Croatian identity irrespective of constitutional status within the Habsburg Monarchy and, later, the Kingdom of Serbs, Croats and Slovenes (after 1918) and the Kingdom of Yugoslavia.
Central to the modern flag is the šahovnica, a shield of 25 alternating red and white squares, arranged with a red square in the upper-left position in current practice. Above it sits a stylised crown of five smaller shields representing the historical regions: the oldest known Croatian coat (with a star and crescent), Dubrovnik, Dalmatia (three golden leopards’ heads), Istria (a golden goat), and Slavonia (marten and stars). This heraldic ensemble, introduced in 1990, aimed to unify regional identities within a single national symbol.
Under socialist Yugoslavia (1945–1990), the Croatian republican flag consisted of the same tricolour but with a red star bordered in yellow at the centre. As Croatia moved toward independence in 1990–1991, the star and associated socialist insignia were removed. The current coat of arms was defined in law with precise graphic standards, ensuring consistent rendition across print, textile, and digital media. The national flag ratio is typically 1:2, with equal stripe widths and the arms centred vertically and horizontally.
Flag law and protocol specify dignified treatment: correct orientation of the coat of arms, half-masting procedures, and precedence when flown with European Union and other flags. State and military standards include additional devices and fringes for ceremonial use, while the plain national flag is used by citizens and most institutions. Misuse or desecration is subject to penalties within administrative codes.
The Croatian flag’s fusion of simple tricolour and distinctive arms has proven effective in public life. It flies on statehood commemorations, at embassies, and in stadiums where diaspora communities gather. The checkerboard’s visibility across Croatian culture—on sports jerseys, municipal arms, and historic architecture—creates a powerful feedback loop that reinforces recognition of the national flag itself.
By adopting an historically grounded yet legally standardized design in 1990, Croatia articulated a narrative of continuity and renewal. The flag presents Croatia as one among the European family of tricolours—democratic and sovereign—while the šahovnica anchors that identity in a uniquely Croatian heraldic language.
