I'm only an AS student so please don't attack me if I'm not 100% right, k :) (by the way its Spelt Russification so that might be limiting your finds)

Russification was the policy put into place by Alexander III, he wanted Russia to be united under one language and religion, Non-Russians such as Poles, Jews or Finns (and many other national minorities) were forced to adopt the Russian language and accept the religion of the Russian Orthadox Church.

Russification was also an attempt by Alexander III's government to restrict the influence of the national minorities within the Russian Empire. Sources : Reactions & Revolutions: Russia 1881-1924 Michael Lynch second edition
