The process of polonization took place over a lengthy period of time. At first only the highest members of the nobility were involved, although gradually a wider group of the population was affected. The major effects on the lesser Lithuanian nobility took place after various sanctions were imposed by the Russian Empire such as removing Lithuania from the names of the Gubernyas few years after the November Uprising. After the January Uprising the sanctions went further, and Russian officials announced that "Lithuanians are Russians seduced by Poles and Catholicism" and began to intensify russification, and to ban the printing of books in the Lithuanian language.

Q: What did the russian officials announce as a sanction?
"Lithuanians are Russians seduced by Poles and Catholicism"
