Cisalpine Gaul

Sponsorship the way you would do it
Province of the Roman Republic, in modern-day northern Italy. It was Rome's third province (after Sicily and Corsica), and was merged into Italia in 42 BC, as part of Octavian's 'Italicisation' program during the Second Triumvirate.

Julius Caesar used Gallia Cisalpina for the 'good guys' in Gaul (Gallia) on this side of the Alps from Caesar's point of view (Rome) - and Gallia Transalpina for Gallia on the other side of the Alps.

"Gallican" was used for both areas of course.
