Yep. For example.....
"British public opinion was divided on the American Civil War. The Confederacy tended to have support from the elites: the aristocracy and the gentry, which identified with the landed plantation owners, and Anglican clergy and some professionals who admired tradition, hierarchy and paternalism. The Union was favored by the middle classes, the religious Nonconformists, intellectuals, reformers and most factory workers, who saw
slavery and forced labor as a threat to the status of the workingman. The cabinet made the decisions. Chancellor of the Exchequer William E Gladstone, whose family fortune had been based on slavery in the West Indies before 1833, supported the Confederacy. Foreign Minister Lord Russell wanted neutrality. Prime Minister Lord Palmerston wavered between support for national independence, his opposition to slavery and the strong economic advantages of Britain remaining neutral.[10]"
"The Confederate States came into existence after seven of the fifteen slave states seceded because of the election of Republican President Lincoln, whose party committed to the containment of slavery geographically and the weakening of slaveowners' political power. Slavery was the cornerstone of the South's plantation economy, although
it was repugnant to the moral sensibilities of most people in Britain, which had abolished slavery in its Empire in 1833. "
