Concubines are women who have a recognized relationship with a man, often in a context where marriage is not the primary arrangement. Historically, they were often part of royal or wealthy households, serving as secondary partners to a primary wife. Concubines typically had fewer legal rights than wives and their children might not inherit the same status or wealth. In many cultures, such as in ancient China and Middle Eastern societies, concubinage was a common practice. The role of concubines varied, with some enjoying a degree of influence and others living more restricted lives. The practice has largely diminished in modern times due to changing social norms and legal frameworks.
