The disastrous events in the Caucasus which came some years after, are believed to be due to Paskevich's and Mir-Fatah's departures from office, and bad ruling policies of subsequent governor generals, which forced him to return to Tabriz in 1841. Soon after his departure, the situation in the Caucasus worsened with the rise of figures such as Imam Shamil and others. It would take Russia around 50 years to fully annex the North Caucasus.
