Who were the white Russians in the Russian revolution?

The White Russians followed the Czar, Nicholas II. This was comprised of Loyalists and cossacks. The Red Russians, were part of the Red Army lead by the communist Bolsheviks, and Vladimir Lenin.

In point of fact, there were no "White Russians" in the "Russian Revolution." The White Russian forces were part of the Russian Civil War, not the revolution. The White Russians were not all followers of Tsar Nicholas II. Many did not want him back in power. The White Russians were mainly anti-Soviet and anti-Bolshevik forces. Some wanted to impose a military dictatorship over Russia, some wanted a constitutional democracy and some wanted simply to be left alone to live without interference by the Moscow government. This dichotomy of goals is partly to blame for the failure of the White Russians in the civil war.

@EPLibraian: While yes it may be true some were not particularly Pro-czar they did fight on the same side of the Czar against the Red Army. In fact, the term "white" comes from a reference of absolute monarchy used with Ivan III, the first czar of Russia, not a military dictatorship. The White Russians also comprised of the members I stated (Loyalists and Cossacks). Famous members of this army include the Russian naval commander Alexander Kolchak and military intelligence officer Lavr Kornilov, as well as fictional characters General Zaroff, and his manservant Ivan from the short story The Most Dangerous Game, which denotes Nicholas as the "Great White Czar." Either way the confederation was extremely loose due to their divided goals, as you stated. and i am sorry for not particularly clarifying my answer
