Republic / Plurinational State of Bolivia
Who & why: Simón Bolívar declines the presidency of the new republic, and Antonio José de Sucre becomes its first president in 1825; the country is named “Bolivia” directly after Bolívar, one of very few nations in the world named after a real person. The War of the Pacific (1879–84) against Chile, fought alongside allied Peru, ends in defeat: Bolivia loses its entire Pacific coastline and becomes landlocked, a defining and still keenly felt national loss. The country's official name changes to the “Plurinational State of Bolivia” in 2009 under a new constitution, without altering the flag itself.
What it represents: the horizontal red-yellow-green triband, with colors fixed in 1851 and current proportions and details set in 1888, has remained stable ever since. The plain civil flag shown here omits the national coat of arms that sits centered on the state and war-ensign versions.
