In 1992 Checheno-Ingushetia divided into two separate republics: Chechnya and Ingushetiya. Dudayev pursued aggressively nationalistic, anti-Russian policies, and during 1994 armed Chechen opposition groups with Russian military backing tried unsuccessfully to depose Dudayev. On December 11, 1994, Russian troops invaded Chechnya. Overcoming stiff resistance, the Russian forces took the capital city of Grozny (Dzhokhar) in March 1995.
