Foreign alliances of France
The foreign alliances of France have a long and complex history spanning more than a millennium. One traditional characteristic of the French diplomacy of alliances has been the "Alliance de revers" (i.e. "Rear alliance"), aiming at allying with countries situated on the opposite side or "in the back" of an adversary, in order to open a second front encircling the adversary and thus re-establish a balance of power. Another has been the alliance with local populations, against other European colonial powers.
