Of all the flag pairs that get confused for one another, Romania and Chad are in a league of their own. Both fly a vertical tricolor of blue, yellow, and red, in the exact same order, at the exact same proportions. Put them side by side and the only real difference is a slightly darker blue on Chad’s version, something you’d only catch under good light with both flags in front of you.
The strange part is that the resemblance is a complete coincidence. Romania’s tricolor goes back to 1848, drawn from the historical colors of its three regions, Wallachia, Moldavia, and Transylvania. Chad’s flag wasn’t adopted until more than a century later, in 1959, just ahead of independence from France. Chad’s early design actually used green instead of blue, in line with the pan-African colors seen on flags like Ethiopia’s. It got dropped at the last minute because it looked too close to Mali’s flag, and blue was swapped in instead, without anyone apparently noticing it now looked almost exactly like Romania’s.
For a while the two flags weren’t quite twins. Romania’s version carried a Communist-era coat of arms in the center from the late 1940s until 1989, when it was cut out by protesters during the revolution that overthrew Nicolae Ceaușescu. Once that emblem was removed, Romania’s flag became a plain tricolor again, identical to the one Chad had already been flying for three decades.
The similarity has actually caused a bit of diplomatic friction. In 2004, Chad reportedly raised the issue with the United Nations. Romania’s response, delivered by then-president Ion Iliescu, was blunt: the tricolor was Romania’s before Chad existed as a country, and it wasn’t changing. Nothing came of it, and both nations still fly the same three colors today.
So if you ever spot a blue, yellow, and red flag and can’t immediately tell which country it belongs to, don’t feel bad. Even the two governments involved have never fully settled the matter.
