Why, after the abolition of serfdom, the state faced the need to carry out other reforms?

The abolition of serfdom was only the first step towards transformations in the state. The need to make Russia a leading industrial, agrarian, educated power pushed the government towards reforms in all sectors of the economy.
In addition, the abolition of serfdom gave rise to the need to remake the entire established order of land ownership, since it was necessary to secure the right to land plots for the peasants. It was a laborious and complicated process, like any reform.
