Tripolitania (Roman province)

Following the defeat of Carthage in the Punic Wars, Ancient Rome organized the region (along with what is now modern day Tunisia and eastern Algeria), into a province known as Africa, and placed it under the administration of a proconsul.

Tripolitania was the least urbanized region in Roman Africa.

[1] During the Diocletian reforms of the late 3rd century, all of North Africa was placed into the newly created Diocese of Africa, of which Tripolitania was a constituent province.

In the 19th century, some scholars debated the location of the classical sites within contemporary Ottoman Tripolitania.

For example, Sabratha had been referred to by sailors as "Old Tripoli" and some classical names (e.g. Oea, Neapolis, Abrotonum) were no longer in modern use.
