Ravenna (Romagnol: Ravêna) is the capital city of the Province of Ravenna in the Emilia-Romagna region of Italy. It was the capital city of the Western Roman Empire from 402 until that empire collapsed in 476. It then served as the capital of the Kingdom of the Ostrogoths until it was re-conquered in 540 by the Eastern Roman (Byzantine) Empire. Afterwards, the city formed the centre of the Byzantine Exarchate of Ravenna until the invasion of the Franks in 751, after which it became the seat of the Kingdom of the Lombards.
The origin of the name Ravenna is unclear, although it is believed the name is Etruscan. Some have speculated that "ravenna" is related to "Rasenna" (later "Rasna"), the term that the Etruscans used for themselves, but there is no agreement on this point.
The origins of Ravenna are uncertain. The first settlement is variously attributed to (and then has seen the co presence of) the Thessalians, the Etruscans and the Umbrians, afterwards its territory was settled also by the Senones, especially the southern countryside of the city (that wasn't part of the lagoon), the Ager Decimanus. Ravenna consisted of houses built on piles on a series of small islands in a marshy lagoon – a situation similar to Venice several centuries later. The Romans ignored it during their conquest of the Po River Delta, but later accepted it into the Roman Republic as a federated town in 89 BC. In 49 BC, it was the location where Julius Caesar gathered his forces before crossing the Rubicon. Later, after his battle against Mark Antony in 31 BC, Emperor Augustus founded the military harbor of Classe. This harbor, protected at first by its own walls, was an important station of the Roman Imperial Fleet. Nowadays the city is landlocked, but Ravenna remained an important seaport on the Adriatic until the early Middle Ages. During the German campaigns, Thusnelda, widow of Arminius, and Marbod, King of the Marcomanni, were confined at Ravenna.
Ravenna greatly prospered under Roman rule. Emperor Trajan built a long aqueduct at the beginning of the 2nd century. During the Marcomannic Wars, Germanic settlers in Ravenna revolted and managed to seize possession of the city. For this reason, Marcus Aurelius decided not only against bringing more barbarians into Italy, but even banished those who had previously been brought there. In AD 402, Emperor Honorius transferred the capital of the Western Roman Empire from Milan to Ravenna. At that time it was home to 50,000 people. The transfer was made partly for defensive purposes: Ravenna was surrounded by swamps and marshes, and was perceived to be easily defensible (although in fact the city fell to opposing forces numerous times in its history); it is also likely that the move to Ravenna was due to the city's port and good sea-borne connections to the Eastern Roman Empire. However, in 409, King Alaric I of the Visigoths simply bypassed Ravenna, and went on to sack Rome in 410 and to take Galla Placidia, daughter of Emperor Theodosius I, hostage. After many vicissitudes, Galla Placidia returned to Ravenna with her son, Emperor Valentinian III and the support of her nephew Theodosius II. Ravenna enjoyed a period of peace, during which time the Christian religion was favoured by the imperial court, and the city gained some of its most famous monuments, including the Orthodox Baptistery, the misnamed Mausoleum of Galla Placidia (she was not really buried there), and San Giovanni Evangelista.
The late 400s saw the dissolution of Roman authority in the west, and the last person to hold the title of emperor in the West was deposed in 476 by the general Odoacer. Odoacer ruled as King of Italy for 13 years, but in 489 the Eastern Emperor Zeno sent the Ostrogoth King Theoderic the Great to re-take the Italian peninsula. After losing the Battle of Verona, Odoacer retreated to Ravenna, where he withstood a siege of three years by Theoderic, until the taking of Rimini deprived Ravenna of supplies. Theoderic took Ravenna in 493, supposedly slew Odoacer with his own hands, and Ravenna became the capital of the Ostrogothic Kingdom of Italy. Theoderic, following his imperial predecessors, also built many splendid buildings in and around Ravenna, including his palace church Sant'Apollinare Nuovo, an Arian cathedral (now Santo Spirito) and Baptistery, and his own Mausoleum just outside the walls.
Theoderic died in 526 and was succeeded by his young grandson Athalaric under the authority of his daughter Amalasunta, but by 535 both were dead and Theoderic's line was represented only by Amalasuntha's daughter Matasuntha. Various Ostrogothic military leaders took the kingship of Italy, but none were as successful as Theoderic had been. Meanwhile, the orthodox Christian Byzantine Emperor Justinian I, opposed both Ostrogoth rule and the Arian variety of Christianity. In 535 his general Belisarius invaded Italy and in 540 conquered Ravenna. After the conquest of Italy was completed in 554, Ravenna became the seat of Byzantine government in Italy.
From 540 to 600, Ravenna's bishops embarked upon a notable building program of churches in Ravenna and in and around the port city of Classe. Surviving monuments include the Basilica of San Vitale and the Basilica of Sant'Apollinare in Classe, as well as the partially surviving San Michele in Africisco.
Exarchate of Ravenna
Following the conquests of Belisarius for the Emperor Justinian I in the 6th century, Ravenna became the seat of the Byzantine governor of Italy, the Exarch, and was known as the Exarchate of Ravenna. It was at this time that the Ravenna Cosmography was written.
Under Byzantine rule, the archbishop of Ravenna was temporarily granted autocephaly from the Roman Church by the emperor, in 666, but this was soon revoked. Nevertheless, the archbishop of Ravenna held the second place in Italy after the pope, and played an important role in many theological controversies during this period.
Middle Ages and Renaissance
The Lombards, under King Liutprand, occupied Ravenna in 712, but were forced to return it to the Byzantines. However, in 751 the Lombard king, Aistulf, succeeded in conquering Ravenna, thus ending Byzantine rule in northern Italy.
King Pepin of France attacked the Lombards under orders of Pope Stephen II. Ravenna then gradually came under the direct authority of the popes, although this was contested by the archbishops at various times. Pope Adrian I authorized Charlemagne to take away anything from Ravenna that he liked, and an unknown quantity of Roman columns, mosaics, statues, and other portable items were taken north to enrich his capital of Aachen.
In 1198 Ravenna led a league of Romagna cities against the Emperor, and the Pope was able to subdue it. After the war of 1218 the Traversari family was able to impose its rule in the city, which lasted until 1240. After a short period under an Imperial vicar, Ravenna was returned to the Papal States in 1248 and again to the Traversari until, in 1275, the Da Polenta established their long-lasting seigniory. One of the most illustrious residents of Ravenna at this time was the exiled poet Dante. The last of the Da Polenta, Ostasio III, was ousted by the Republic of Venice in 1440, and the city was annexed to the Venetian territories.
After the Venetian withdrawal, Ravenna was again ruled by legates of the Pope as part of the Papal States. The city was damaged in a tremendous flood in May 1636. Over the next 300 years, a network of canals diverted nearby rivers and drained nearby swamps, thus reducing the possibility of flooding and creating a large belt of agricultural land around the city.
Apart from another short occupation by Venice (1527–1529), Ravenna was part of the Papal States until 1796, when it was annexed to the French puppet state of the Cisalpine Republic, (Italian Republic from 1802, and Kingdom of Italy from 1805). It was returned to the Papal States in 1814. Occupied by Piedmontese troops in 1859, Ravenna and the surrounding Romagna area became part of the new unified Kingdom of Italy in 1861. During World War II two troops of the British 27th Lancers entered and occupied Ravenna on 5 December 1944. The town suffered very little damage.
