Many also forget that the international campaign in solidarity with the Union under the Lincoln presidency rallied at a time when it was entirely possible that the United Kingdom might have thrown its whole weight behind the Confederacy and even moved troops from Canada to hasten the partition of a country half slave and half free. This is often forgotten, I suggest, because the movement of solidarity was partly led by Karl Marx and his European allies (as was gratefully acknowledged by Henry Adams in his Education)
that time Karl Marx helped save the union #USA
