Why are colonies needed?

The very term “colonies” was invented by the ancient Romans, as they called the settlements outside Italy. Roman citizens settled there in the occupied lands from the peoples that the Romans considered barbaric. Thus, Latin and Roman culture spread, for example, stadiums, aqueducts, bridges and roads. The population in the colony could be up to 6 thousand.
The main one for creating a colony is the Roman camp (castrum) in the occupied territory (hence the toponym “Castel” in the Crimea), it could have been built on the site of some settlement of Gauls, Celts and other peoples.
Before the Romans, colonies were created by the Greeks (from Colchis to the south of Spain) and the Phoenicians (the most famous is Carthage). Colonies were needed to resettle the surplus population and to trade with local residents. The colony was reborn in the 16th and early 20th centuries. The first to create them were the Spaniards and the Portuguese, then the Dutch, the British, the French followed them, and from the 1870s – the Germans, Belgians and Italians.
