The state in which the feudal landowning class exercised political rule over the peasants. It was another type of exploitative class dictatorship that emerged after the collapse of the slave state. In China, a feudal state was formed around the 5th century BC and its rule lasted for more than 2,300 years. In Europe, from the fall of the Western Roman Empire in the late 5th century A.D. to the bourgeois revolutions of the 17th and 18th centuries, the history of the feudal state was also more than 1,300 years. Feudal society was an agrarian society with a predominantly natural economy, where land was the primary means of production and land ownership was the core of production relations in feudal society. For most of the time in Western feudal society, feudal lordship was the dominant form of land tenure; in China, landlord tenure was the dominant form of land tenure. The essence of these two forms of land tenure was the same, i.e., the land was occupied by the privileged big landholders, and the peasants cultivated the land of the lords or landlords, handing over their surplus labor to the landholders free of charge under the super-economic coercion. This determined that the main contradiction in feudal society was the contradiction between the peasant class and the class of large landholders. The feudal state, which was built on the basis of feudal land ownership, was an instrument of political domination and oppression of the peasant class by the feudal landlord class in order to maintain its class rule.
