Final answer:
The Church dominated all aspects of peasant life in Feudal Europe by being a major landowner, provider of spiritual services marking life's stages, and a collector of tithes and rents.
Step-by-step explanation:
The Church worked to dominate all aspects of peasant life in Feudal Europe through various means. As Christianity spread throughout Europe, the Church replaced pagan and animistic beliefs and became a central part of life, marking every life stage with sacraments. Each village and family's life revolved around the Church calendar. Furthermore, the Church, as a landowner and recipient of tithes, rents, and offerings, accrued great wealth and power.
The medieval feudal system created a dependency where peasants worked the land in return for protection and basic sustenance, often under church-owned fiefs. Monasteries and bishoprics, like secular lords, owed and were owed services, with religious figures sometimes being feudal lords themselves. Even after the decline of feudalism following events such as the Black Death, the Church remained influential, being a central institution affecting both social and political spheres.
Lords provided protection and lands, and in turn, peasants were obliged to serve their lords and—the Church. Contributions to the Church were not only spiritual but also material, through tithes and rents, which further ensured the Church's dominance in feudal society.
