Sicily was colonized by Greeks in the 8th century BC. Initially, this was restricted to the eastern and southern parts of the island. The most important colony was established at Syracuse in 734 BC. Other important Greek colonies were Gela, Akragas, Selinunte, Himera, Kamarina and Zancle or Messene (modern-day Messina, not to be confused with the ancient city of Messene in Messenia, Greece). These city-states were an important part of classical Greek civilization, which included Sicily as part of Magna Graecia – both Empedocles and Archimedes were from Sicily.
