The reasons for the successful economy and development of the country in the second half of the 19th century?

The peasant reform led to the stratification of the peasantry: the richest owners and the poor stood out. An accelerated destruction of the natural economy began to take place, and workers appeared in factories and plants. This allowed industrial production to begin to develop: such industries as mechanical engineering, the coal industry appear, a railway network is being built. All this leads to an industrial revolution and socio-economic development of the country.
