Why was serfdom abolished? What are the reasons for the cancellation.

In Russia, the moment has come when the discontent of the bulk of the population, which was the peasantry, could at any moment develop into an uprising. In the course of such an uprising, serfdom could be abolished from below on conditions that were beneficial to the peasants. The government decided not to allow this, so it adopted a Manifesto on the abolition of serfdom on those conditions that were beneficial to him and the nobility (the power relied on this estate), that is, it abolished serfdom from above.
