Foundation and First Mentions
The history of Cagliari is rooted in deep antiquity. Although traces of human presence in this area date back to the Neolithic period, the actual foundation of the city as an organized trading settlement is attributed to the Phoenicians in the 8th–7th centuries BC. In ancient sources, the city is mentioned under the name Karalis, which likely meant "rocky place".
Key Development Factors
The development of Cagliari as the main city of Sardinia was predetermined by a combination of unique natural and geopolitical conditions:
- Geography and Defence: The city grew on hills that provided natural defence and possessed a deep harbour protected from winds in the Gulf of Angels, ideal for naval fleets.
- Maritime Trade: Cagliari occupied a key position at the crossroads of trade routes between North Africa, Italy, and Spain, controlling maritime traffic in the Tyrrhenian Sea.
- Political Power: With the transition under the rule of Carthage in the 6th century BC, and later Rome in the 3rd century BC, the city established itself as the administrative centre of the province.
Early Cultural and Economic Features
The economy and culture of early Cagliari were shaped by the influence of maritime trade and the succession of civilizations:
- Economic Base: Wealth was primarily derived from salt extraction in coastal lagoons, and the export of grain and metals mined in the island's interior.
- Punic Heritage: The significance of the city during the Carthaginian period is evidenced by the Tuvixeddu necropolis — the largest Punic burial site in the Mediterranean, which has survived to this day.
- Roman Urbanization: In the Roman period, the city received the status of a municipium, leading to rapid construction: paved streets, aqueducts, and a majestic amphitheatre carved directly into the rock appeared.
