How did the landowning nobles affect the russian industrialization process and reforms?

A great obstacle to progress was the rigid social structure. Landowning nobles dominated society and rejected any change that would threaten their privileges. The middle class was too small to have much influence. The majority of Russians were serfs, or laborers bound to the land and to masters who controlled their fates.

Most serfs were peasants. Others were servants, artisans, or soldiers forced into the tsar’s army. As industry expanded, some masters sent serfs to work in factories but took much of their pay.
