Sardinia History & Heritage Guide 2025

The earliest inhabitants of Sardinia arrived from mainland Europe and North Africa around 6000 BC. Pre-Nuragic cultures include the Ozieri culture (3200–2700 BC), famous for its extraordinary pottery, and the builders of the Domus de Janas (fairy houses) — rock-cut tombs carved into the island's limestone. The Bonu Ighinu and Arzachena cultures created megalithic monuments including the proto-nuraghi and the first Giants' Tombs.

The most remarkable and mysterious of Sardinian cultures, the Nuragic civilisation flourished for over 1,500 years and constructed more than 7,000 truncated-cone towers (nuraghi) across the island. The Nuragic people were sophisticated bronze-smiths, traders who reached Mycenaean Greece, Phoenicia, and Egypt, and creators of extraordinary art including the famous bronzetti (small bronze figurines). They buried their dead in collective tombs called tombe di giganti (Giants' Tombs). The Nuragic civilisation appears to have no clear parallel in the Mediterranean world.

Phoenician traders from Tyre and Sidon began establishing trading posts on Sardinia's coasts around 900 BC. The key Phoenician settlements included Tharros (near Oristano), Nora (near Pula), Cagliari (Karalis), and Sulcis (Sant'Antioco). The Phoenicians coexisted with the Nuragic people in coastal areas, maintaining trade and cultural exchange while the interior remained Nuragic. When Carthage superseded Phoenicia, these settlements became Punic (Carthaginian) towns.

Rome seized Sardinia from Carthage in 238 BC following the First Punic War. Sardinia became one of Rome's first overseas provinces and a major grain and silver supplier. Roman rule was accepted in the coastal cities but fiercely resisted in the interior — the Barbagia mountains were among the last areas of the entire Roman Empire to be Christianised. Emperor Augustus described the island as unhealthy and barely worth holding. Despite this, Sardinia received significant Roman infrastructure: roads, theatres, amphitheatres, and temples.

After Rome's collapse, Sardinia passed to the Vandals (456 AD) and then to the Byzantine Empire (534 AD). Byzantine rule lasted several centuries and left churches and fortifications, though the interior remained largely autonomous. From the 8th century, Arab raids began devastating the Sardinian coasts, forcing many coastal populations to move inland. In response, local Sardinian leaders (giudici — judges) established four independent kingdoms: Cagliari, Arborea, Torres, and Gallura.

The Italian maritime republics of Pisa and Genoa competed for influence in Sardinia during the Middle Ages, leaving behind a remarkable legacy of Romanesque churches and fortifications. Pisa controlled the south (Cagliari), while Genoa held the north. This period saw the construction of many of Sardinia's most beautiful Romanesque churches in pale limestone, often remote in the countryside.

In 1297, Pope Boniface VIII granted the 'Kingdom of Sardinia and Corsica' to the Crown of Aragon. Aragon had to fight for the island against the Giudicato of Arborea — the last independent Sardinian state, which held out until 1420 under the heroic Judge Eleonora d'Arborea, who issued the Carta de Logu (a progressive legal code). Under 400 years of Spanish rule, Sardinian society was feudalised, the economy declined, and much of the coastal population retreated from piracy. Alghero was repopulated with Catalan settlers in 1354 and retains its Catalan character to this day.

Following the War of the Spanish Succession, Sardinia was transferred to the Duke of Savoy in 1718 in exchange for Sicily. The Savoyard Kings of Sardinia gave the island its formal title (Kingdom of Sardinia) and established Turin as the royal capital of a state that would eventually unify Italy. Sardinia remained largely feudal and underdeveloped under Savoy, though the abolition of feudalism in 1820 began a slow modernisation.

Sardinia became part of unified Italy in 1861. The 20th century brought significant changes: the drainage of malarial marshes, construction of new towns, the Second World War (Cagliari was heavily bombed), and post-war economic challenges driven by the collapse of traditional mining. In 1948, Sardinia gained Special Autonomous Region status, giving it greater control over its affairs. Since the 1960s, the tourism industry — particularly Costa Smeralda, developed by the Aga Khan in 1962 — has transformed the northern economy. Today Sardinia remains one of Italy's five special autonomous regions.
