The former flag of Libya had been adopted in November 1977 and was used until 2011. The flag consisted of a green field without a crest or insignia and was the only single color flag in the world. Although uncommon, other countries have used single colored flags: Afghanistan, France, and the Sultanate of Muscat.

Leptis Magna was an important trading city within the Roman Empire. The well preserved ruins are near the Libyan city of Khoms. Founded in 1000 BC, the city remained unknown until Carthage asserted itself as the leading Mediterranean power. Leptis fell under Roman control following Carthage’s defeat in the Third Punic War. The city reached its apex when Lucius Septimius Severus, a native of the city, became emperor. Under his patronage, Leptis Magna soon rivaled Alexandria and Carthage as Rome’s most important African city.
