During the 19th century, the social structure changed dramatically. A class of independent farmers established itself after reforms allowed the peasants to repurchase their land, but many landless peasants remained. There also developed a growing urban proletariat and an increasingly influential Latvian bourgeoisie. The Young Latvian () movement laid the groundwork for nationalism from the middle of the century, many of its leaders looking to the Slavophiles for support against the prevailing German-dominated social order. The rise in use of the Latvian language in literature and society became known as the First National Awakening. Russification began in Latgale after the Polish led the January Uprising in 1863: this spread to the rest of what is now Latvia by the 1880s. The Young Latvians were largely eclipsed by the New Current, a broad leftist social and political movement, in the 1890s. Popular discontent exploded in the 1905 Russian Revolution, which took a nationalist character in the Baltic provinces.
