The history of Annaba, one of the oldest cities in Algeria, dates back centuries. The city was founded by the Phoenicians around the 12th century BC as a trading post named Hippo. Later, it became one of the capitals of the Numidian Kingdom, earning the honorary suffix "Royal" — Hippo Regius. It is under this name that it entered the annals of world history as one of the most important centers of late antiquity.
Key factors in the city's establishment were its strategic location on the Mediterranean coast and its convenient natural harbor. This made Hippo a vital trade hub through which maritime routes passed. However, the city gained true fame not only through commerce but also through spiritual authority. In the 4th and 5th centuries AD, one of the fathers of the Christian church lived and preached here — Saint Augustine, Bishop of Hippo. His activities turned the city into one of the main intellectual and religious centers of the Roman Empire.
The city's early economy was closely tied to maritime trade and agriculture in the fertile surrounding lands. After the fall of Rome, the city survived conquests by the Vandals, Byzantines, and Arabs. In the 11th century, a new city was founded slightly away from the ruins of ancient Hippo, named Beleb-el-Anab, which means "City of Jujubes" (a fruit tree). Over time, this name transformed into the modern Annaba. During the colonial period, the city, known as Bône, once again became a major port, retaining its economic significance to this day.
