Feodum is a Latin term that refers to a medieval system of land tenure, also known as feudalism. Some synonyms for the word feodum include fiefdom, manor, estate, and domain. Fiefdom emphasizes the power and authority associated with the land, while manor emphasizes the residence and agricultural aspects. Estate and domain both imply ownership over a large area of land, and are often associated with the wealthiest and most powerful members of society. Feodalismus, the Latin term for feudalism, is also a synonym for feodum. While this system is no longer in use today, it remains an important part of historical understanding and study.
