Language too played an important role in developing nationalist sentiments.
After Russian occupation, the Polish language was forced out of schools and the Russian language was imposed everywhere.
In 1831, an armed rebellion against Russian rule took place which was ultimately crushed. Following this, many members of the clergy in Poland began to use language as a weapon of national resistance.
Polish was used for Church gathering and all religious instructions.
As a result, a large number of priests and bishops were put in jail or sent to Siberia by the Russian authorities as punishment for their refusal to preach in Russia.
The use of Polish came to be seen as a symbol of the struggle against Russian dominance.
