context_page_description: Constantine, also spelled Qacentina or Kasantina, is the capital of Constantine Province in northeastern Algeria. During Roman times it was called Cirta and was renamed "Constantina" in honor of emperor Constantine the Great. It was the capital of the French department of Constantine until 1962. Located somewhat inland, Constantine is about 80 kilometres from the Mediterranean coast, on the banks of the Rhumel River.
  Constantine is regarded as the capital of eastern Algeria and the commercial center of its region, and it has a population of about 450,000, making it the third largest city in the country after Algiers and Oran. There are several museums and historical sites located around the city. Constantine is often referred to as the "City of Bridges" due to the numerous picturesque bridges connecting the various hills, valleys, and ravines that the city is built on and around.
  Constantine was named the Arab Capital of Culture in 2015.
context_section_description: The city was originally founded by the Phoenicians, who called it Sewa (royal city). Later it was renamed Cirta by the Numidian king Syphax, who turned it into his capital. The city was taken over by Numidia, the country of the Berber people, after the Carthaginians  were defeated by Rome in the Third Punic War. In 112 B.C., the city was occupied by the Numidian king Jugurtha, who defeated his half-brother Adherbal. The city later served as the base for Roman generals Quintus Caecilius Metellus Numidicus and Gaius Marius in their war against Jugurtha. Later, with the removal of King Juba I and the remaining supporters of Pompey in Africa (c. 46), Julius Caesar gave special rights to the citizens of Cirta, now known as Colonia Sittlanorum.
  In 311 AD, during the civil war between emperor Maxentius and usurper Domitius Alexander (a former governor of Africa), the city was destroyed. Rebuilt in 313 AD, it was subsequently named in Latin as "Colonia Constantiniana" or "Constantina", after emperor Constantine the Great, who had defeated Maxentius. Captured by the Vandals in 432, Constantine returned to the Byzantine Exarchate of Africa (i.e. North Africa) from 534 to 697. It was conquered by the Arabs in the 8th century, receiving the name of Qacentina.
  During the 11th century, Banu Hilal, an Arab tribe living between Nile and Red Sea, settled in Tunisia, Tripolitania (western Libya) and Constantinois (eastern Algeria) which was Constantine party.
