He introduced a military school, several textile factories and restored the Corpus Christi Church and opened a print works.

Michał's wife, Franciszka Urszula Radziwiłłowa, founded the Nieśwież Radziwiłł Theatre, including a choir and a ballet school.

Between 1764 and 1768 the city was occupied by Russian troops, and in 1772, at the First Partition of Lithuania-Poland, the library, which comprised circa 10,000 volumes, along with paintings and other art objects, was seized and transferred to St. Petersburg.

In 1906, the Polish Society "Oświata" ("Education") in Nesvizh was established, but its activities were hampered by the Russian administration, before banning it at the start of 1910.

The city came under Soviet rule in early 1919 (Polish–Soviet War), the unsuccessful Nieśwież uprising by Polish residents took place during March 14–19, 1919.
