Starting in 1918 religious freedoms were restricted. Churches and congregations had to be registered with the government. Ministers were disenfranchised and lost their rights as citizens. Ministers could not be teachers, which was the livelihood of many Mennonite pastors. They and their family members could not join cooperatives or craft guilds. Because of these restrictions, ministers had a strong incentive to emigrate, and few were willing to replace them. Congregations could no longer do charitable work of any kind, which destroyed the well developed social institutions with the Mennonite colonies. Villages lost control of their schools; all religious content was prohibited. Sunday was abolished as a holiday.
