Cagliari was inhabited since pre-historic periods for its favourable position between the sea and a fertile plain, its being sourrounded by two swamps (which afforded defences from enemies from inner lands) and its vicinity to high and green mountains (to which people could evacuate if everything else was lost).
When Sardinia was finally conquered by Aragon, Cagliari became the administrative capital of the vice-kingdom of Sardinia, which later came under the rule of the Spanish empire; the Spanish domination was a period of decadence for Cagliari and Sardinia.
Cagliari was strategically important during the war because of its location in the Mediterranean Sea.
It is finely situated at the northern extremity of the Gulf of Cagliari, in the centre of the south coast of the island.
The harbour of Cagliari (along the north side of which runs a promenade called the Via Romo) is a good one, and has a considerable trade, exporting chiefly lead, zinc and other minerals and salt, the total annual value of exports amounting to nearly 12 million sterling in value.
The Campidano of Cagliari, the plain which begins at the north end of the lagoon of S. Gilla, is very fertile and much cultivated, as is also the district to the east round Quarto S. Elena, a village with 845 9 inhabitants (1901).
