Why taras shevchenko went to exily?

Taras Shevchenko, the renowned Ukrainian poet and artist, was exiled to Siberia in 1847 primarily for his political activism and his involvement in the Brotherhood of Saints Cyril and Methodius, a secret society that promoted Ukrainian nationalism and sought to advance social reforms. His writings, which criticized the Russian Empire and advocated for the rights of Ukrainians, were deemed subversive. Shevchenko's exile lasted nearly a decade, during which he continued to create significant literary and artistic works despite the harsh conditions.
