Which of the following political concepts is associated with land ownership?

The political concept that is associated with land ownership is Feudalism. Feudalism is a social and economic system that was prominent in medieval Europe, in which land ownership was central to the political and social structure. Under feudalism, the king granted land to lords or nobles in exchange for military service or other duties, and these lords then granted smaller parcels of land to vassals who served them in a similar way. The people who lived and worked on these lands were often serfs, who were tied to the land and could not leave without permission. Therefore, feudalism is associated with the idea that ownership of land is tied to social and political power.
