Expanding population and the associated pressure for more farmland became a problem by 1860. The terms of the settlement agreement prevented farms from being divided; they were required to pass intact from one generation to the next. Since agriculture was the main economic activity, an expanding class of discontented, landless poor arose. Their problems tended to be ignored by the village assembly, which consisted of voting landowners. By the early 1860s the problem became so acute that the landless organized a party that petitioned the Russian government for relief. A combination of factors relieved their plight. The Russian government permitted farms to be divided in half or quarters and ordered release of the village's communal land. The colonies themselves purchased land and formed daughter colonies on the eastern frontier extending into Siberia and Turkestan. These new colonies included Bergtal, Neu Samara Colony and the Mennonite settlements of Altai.
