The secularization of church lands in the XVIII-XIX centuries meant that the lands that were previously owned by the church became the property of the state. This process was part of a larger trend of secularization that was taking place in many parts of Europe during this time period, as the power and influence of the church was being reduced in favor of the state. In Russia, this process was carried out through a series of reforms that were implemented by the government, which resulted in the transfer of church lands to the state. This allowed the government to gain control over these lands and use them for its own purposes, such as for agriculture or for the construction of infrastructure.
