The name Foggia derives from Latin "fovea", meaning "pit", referring to the pits where wheat was stored. Although the area had been settled since Neolithic times, and a Greek colony known as Argos Hippium (in Greek, Ἀργόριππα or Ἀργύριππόι) existed nearby, the first document attesting the existence of the modern city dates from 1000 AD: according to the legend, the first settlers were peasants who had found a panel portraying the Madonna, on which three flames burnt.
The area was marshy and unhealthy, being partially dried under Robert Guiscard, who therefore boosted the economic and social growth of the city. The city was the seat of Henry, Count of Monte Sant'Angelo during the last twenty years of the 11th century. In the 12th century, William II of Sicily built a cathedral here and further enlarged the settlement.
Frederick II had a palace built in Foggia in 1223, in which he often sojourned. It was also seat of his court and a studium, including figures such as Michael Scot, but little of it remains now.
In 1447, King Alfonso V of Aragon built a Custom Palace to tax the local sheep farmers, but this caused a decline of the local economy and the progressive ruin of the land, which again became marshy.
In 1456, an earthquake struck Foggia, followed by others in 1534, 1627 and 1731, the latter destroying one third of the city. The House of Bourbon, however, promoted a certain economic growth by boosting the cereal agriculture of Capitanata and rebuilding much of the settlement.
In the 19th century, Foggia received a railway station and important public monuments. The citizens also took part in the riots, which led to the annexation to Italy in 1861.
By 1865, there was a definitive shift from the custom of sheep farming in favour of an agricultural economy. The historical lack of water resources was solved with the construction of the Apulian aqueduct in 1924, when Foggia was already an important hub
