Holy Alliance

From Turtledove

The Holy Alliance was a military alliance and political union of France and Spain. One of the three major powers of the globe, the Alliance maintained a substantial empire on the Continent as well as abroad. Naturally, the Alliance was engaged in a multi-lateral cold war with Britain and Russia.

They also supported the terrorist group Sons of Liberty, which was active in the North American Union, with arms and money - a completely opportunistic alliance aimed at embarrasing its rival, since obviously the Holy Alliance had little in common with the ideology of "The Sons" and had no interest in creating a precedent of colonies breaking away and becoming indepedent.
