Siena : Italy
Siena did not prosper under Roman rule. It was not sited near any major roads and therefore missed out on the resulting opportunities for trade. Its insular status meant that Christianity did not penetrate until the Fourth Century AD, and it was not until the Lombards invaded Siena and the surrounding territory that it knew prosperity. Their occupation and the fact that the old Roman roads of Aurelia and the Cassia passed through areas exposed to Byzantine raids, caused the roads between the Lombards Northern possessions and Rome to be re-routed through Siena. The inevitable consequence of this was that Siena prospered as a trading post, and the constant streams of pilgrims passing to and from Rome were to prove a valuable source of income in the centuries to come.
The oldest aristocratic families in Siena date their line to the Lombards surrender in 774 to Charlemagne. At this point the city was inundated with a swarm of Frankish overseers who married into the existing Sienese nobility, and left a legacy that can be seen in the abbeys they founded throughout Sienese territory. Feudal power waned however, and by the death of Countess Matilda in 1115 the Mark of Tuscia which had been under the control of her family the Canossa broke up into several autonomous regions.
Siena prospered under the new arrangements, becoming a major centre of money lending and an important player in the wool trade. It was governed at first directly by its Bishop, but episcopal power declined during the 1100s. The bishop was forced to concede a greater say in the running of the city to the nobility in exchange for their help during a territorial dispute with Arezzo, and this started a process which culminated in 1167 when the commune of Siena declared its independence from episcopal control. By 1179, it had a written constitution.
