Roman Sardinia was an important province of the Roman Empire, established in the 3rd century BCE. The island, located in the Mediterranean Sea, was known for its strategic position and rich resources, including grain and minerals. The Romans developed infrastructure, such as roads and cities, to enhance trade and military control. During Roman rule, Sardinia experienced significant cultural and economic changes. The local population, including the Sardinians, was influenced by Roman customs and language. Key cities like Cagliari and Tharros flourished, becoming centers of administration and commerce, which contributed to the island's integration into the Roman world.
