Russian rule offered the Georgians security from external threats, but it was also often heavy-handed and insensitive. By the late 19th century, discontent with the Russian authorities grew into a national revival movement led by Ilia Chavchavadze. This period also brought social and economic change to Georgia, with new social classes emerging: the emancipation of the serfs freed many peasants but did little to alleviate their poverty; the growth of capitalism created an urban working class in Georgia. Both peasants and workers found expression for their discontent through revolts and strikes, culminating in the Revolution of 1905. Their cause was championed by the socialist Mensheviks, who became the dominant political force in Georgia in the final years of Russian rule.
