After 1872: two First Internationals[edit]
Mikhail Bakunin (1814–1876)

internationals.
This split is sometimes called the "red" and "black" divide, red referring to the Marxists and black referring to the anarchists.
Otto von Bismarck remarked upon hearing of the split at the First International that "[c]rowned heads, wealth and privilege may well tremble should ever again the Black and Red unite!".
