At the beginning of the 18th century, wars and plagues brought about a period of decline for manor estates. In the 19th century, all manor estates in Järvamaa were completely destroyed. The development of agriculture and the growth of large estates began. The unification of territories was promoted, and the old system of land tenure was replaced by new agricultural methods. The establishment of large estates and the introduction of new farming methods led to the creation of vast agricultural areas and manor estates. This was the period when Estonia's manor estate structure was formed, and the work of the estates was regulated by strict official statistics. Almost every other Estonian manor had a brewery, many also had distilleries or mills. The estates were owned by Baltic German nobility, who were granted or sold the properties.
The manor estate system reached its peak in the 20th century when the estates were marked by the legal status of the manor estates. One such example is the Võhmuta manor estate, which was established in 1847 and later divided into 1.9 hectares of large Karlsbrunn (Metsamõisa) manor estate and sovereign estate management.

Baron Alexander von Essen's first desire was to establish a manor estate in Järsi village, but the forest management center, which was the manor estate's main source of income, was located in Võhmuta village. The manor house was built in Järsi village, but the economic center remained in Võhmuta. The manor estate included agricultural land, forests, and various buildings necessary for estate management.
