Why did the Russian government close the University of Vilnius in 1832?

The Russian government closed the University of Vilnius in 1832 as part of a broader effort to suppress the influence of the Polish uprisings of 1830–31, which had found significant resonance within Lithuanian lands.123

Following these insurrections, the tsarist government implemented harsh measures to consolidate control over the region, which it began designating as the Northwest Region. The closure of the university was a component of these waves of Russification, aimed at integrating the territory more firmly into the Russian Empire and curbing local nationalist sentiments.123
