In order to "drop" some unreliable and most radical members and to mislead the tsarist authorities, the Moscow meeting of the members of the Korennaya Uprava voted for the dissolution of the UoP in early 1821. Its most active members formed the basis for the establishment of the Northern and Southern Society of the Decembrists.
To achieve this goal, the Moscow gathering of the Korennaya Uprava decided to remove some untrustworthy and most radical individuals from the organization and to create a false impression among the tsarist authorities. This led to the disbanding of the UoP in early 1821, and its most active members went on to establish the Northern and Southern Society of the Decembrists.
