to compensate for the slope of the hill. Construction of this type presupposes organization and political will, and has inspired the name of the neighborhood, "Hannibal district", referring to the Punic general or Suffete at the beginning of the 2nd century BC.
Roman period
When Carthage fell, its nearby rival Utica, a Roman ally, was made capital of the region and replaced Carthage as the leading center of Punic trade and leadership. It had the advantageous position of being situated on the Lake of Tunis and the outlet of the Majardah River, Tunisia's only river that flowed all year long. However, grain cultivation in the Tunisian mountains caused large amounts of silt to erode into the river. This silt was accumulated in the harbor until it was made useless, and Rome was forced to rebuild Carthage.
By 122 BC Gaius Gracchus founded a short-lived colony, called Colonia Iunonia, after the Latin name for the punic goddess Tanit, Iuno caelestis. The purpose was to obtain arable lands for impoverished farmers. The Senate abolished the colony some time later, in order to undermine Gracchus' power.
After this ill-fated attempt a new city of Carthage was built on the same land by Julius Caesar in 49-44 BC period, and by the 1st century A.D. it had grown to be the second largest city in the western half of the Roman Empire, with a peak population of 500,000. It was the center of the Roman province of Africa, which was a major breadbasket of the Empire.
Carthage also became a centre of early Christianity. In the first of a string of rather poorly reported councils at Carthage a few years later, no fewer than seventy bishops attended. Tertullian later broke with the mainstream that was represented more and more in the west by the bishop of Rome, but a more serious rift among Christians was the Donatist controversy, which Augustine of Hippo spent much time and parchment arguing against. In 397 at the Council at Carthage, the biblical canon
