In the 1840s Britain and France considered sponsoring continued independence of the Republic of Texas and blocking U.S. moves to obtain California. Balance of power considerations made Britain want to keep the western territories out of U.S. hands to limit U.S. power; in the end, France opposed such intervention in order to limit British power, the same reason for which France had sold Louisiana to the U.S. and earlier supported the American Revolution. Thus the great majority of the territorial growth of the continental United States was accomplished with French support.
