What city in france was originally a greek city state?

Marseille

Explanation:

The French city of Marseille was founded in 600 BC by the Greeks of Foceia, on the Anatolian peninsula, as a commercial port.

The later development of Massalia, which would reach a significant number of inhabitants and the category of polis (city-state), turned it into a Greek port of reference in Western Europe. Later, by protection, it allied itself to the Roman Republic in its disputes with Etruscans, Celts and Carthaginians. This alliance made the Greek colony thrive thanks to its position as a trade bridge between Rome and the towns of Gaul, facilitating the exchange of manufactured goods, slaves and particularly wine, whose elaboration and cultivation in Marseilles dates back to the fourth century as evidenced by excavations on the hill of Saint-Charles, with the discovery of viticulture substrates, the oldest discovered in France. As a result of his support for the party of Pompey in his dispute with Julius Caesar, he was annexed to Rome by the latter after winning and capturing his fleet, adopting the Latin name of Massilia.
