Agrigento was founded on a plateau overlooking the sea, with two nearby rivers, the Hypsas and the Akragas, and a ridge to the north offering a degree of natural fortification. Its establishment took place around 582-580 BCE and is attributed to Greek colonists from Gela, who named it Akragas.
Akragas grew rapidly, becoming one of the richest and most famous of the Greek colonies of Magna Graecia. It came to prominence under the sixth-century tyrants Phalaris and Theron, and became a democracy after the overthrow of Theron's son Thrasydaeus. Although the city remained neutral in the conflict between Athens and Syracuse, its democracy was overthrown when the city was sacked by the Carthaginians in 406 BCE. Akragas never fully recovered its former status, though it revived to some extent under Timoleon in the latter part of the fourth century.
Didrachm, 490-483 BCE.
The city was disputed between the Romans and the Carthaginians during the First Punic War. The Romans laid siege to the city in 262 BCE and captured it after defeating a Carthaginian relief force in 261 BCE and sold the population into slavery. Although the Carthaginians recaptured the city in 255 BCE the final peace settlement gave Punic Sicily and with it Akragas to Rome. It suffered badly during the Second Punic War (218-201 BCE) when both Rome and Carthage fought to control it. The Romans eventually captured Akragas in 210 BCE and renamed it Agrigentum, although it remained a largely Greek-speaking community for centuries thereafter. It became prosperous again under Roman rule and its inhabitants received full Roman citizenship following the death of Julius Caesar in 44 BCE.
After the fall of the Roman Empire, the city passed into the hands of the Ostrogothic Kingdom of Italy and then the Byzantine Empire. During this period the inhabitants of Agrigentum largely abandoned the lower parts of the city and moved to the former acropolis, at the top of the hill. The reasons for this move are unclear but were probably related to the destructive coastal raids of the Saracens, Berbers and other peoples around this time. In 828 CE the Saracens captured the diminished remnant of the city. They pronounced its name as Kerkent in Arabic; it was thus Sicilianized as "Girgenti". It retained this name until 1927, when Benito Mussolini's government reintroduced an Italianized version of the Latin name.
Agrigento was captured by the Normans under Count Roger I in 1087, who established a Latin bishopric there. The population declined during much of the medieval period but revived somewhat after the 18th century. In 1860, the inhabitants enthusiastically supported Giuseppe Garibaldi in his conquest of southern Italy (in the course of the Unification of Italy). The city suffered a number of destructive bombing raids during World War II.
