Kings' Lands is a term used to describe the territories and domains that are ruled by kings. It is a broad term that can refer to any land that is under the control of a monarch, including both physical and political boundaries. The term is often used in reference to medieval times, when kings had absolute power over their lands. In modern times, the term is still used to refer to the lands that are under the control of a king or queen, although the power of the monarch is usually limited by a constitution or other laws.
