Florence

Florence was originally established by Julius Caesar in 59 BC as a settlement for his veteran soldiers. It was named Florentia (Flourishing) and built in the style of an army camp with the main streets, the cardo and the decumanus, intersecting at the present Piazza della Repubblica. Situated at the Via Cassia, the main route between Rome and the north, and within the fertile valley of the Arno, the settlement quickly became an important commercial centre. The Emperor Diocletian made Florentia the seat of a bishopric around the beginning of the 4th century AD. In the ensuing two centuries, the city experienced turbulent periods of Ostrogothic rule, during which the city was often troubled by warfare between the Ostrogoths and the Byzantines, which may have caused the population to fall to as few as 1,000 living persons.

Peace returned under Lombard rule in the 6th century. Conquered by Charlemagne in 774, Florence became part of the Duchy of Tuscany, with Lucca as capital. Population began to grow again and commerce prospered. In 854, Florence and Fiesole were united in one county.

Margrave Hugo chose Florence as his residency instead of Lucca at about 1000 AD. This initiated the Golden Age of Florentine art. In 1013, construction began on the Basilica di San Miniato al Monte. The exterior of the baptistry was reworked in Romanesque style between 1059 and 1128.
