French is the only official language in Monaco, a result of the role France has had over the microstate (see Franco-Monegasque Treaty) since the annexation of Nice and the Nizzardo (the territory surrounding Monaco), then culturally and ethnically Italian, as part of the Kingdom of Piedmont-Sardinia.
