Marriage treaty

A marriage treaty is a formal agreement made between two families or nations, often to arrange a marriage between specific individuals, usually for political, economic, or strategic purposes. It helps establish alliances, secure peace, or strengthen relationships. The treaty outlines the terms of the marriage, duties, and any related commitments, serving as a legal document to ensure both parties uphold their promises. Historically common among royal or noble families, these treaties played a significant role in diplomacy and power dynamics.
