Joint sovereignty refers to a situation where two or more entities share control over a specific territory or jurisdiction. This arrangement allows each party to exercise certain rights and responsibilities within the area, often leading to collaborative governance. Joint sovereignty can occur between countries, regions, or even local governments. An example of joint sovereignty is the relationship between United Kingdom and Gibraltar, where both have a say in the governance of the territory. This concept can also apply to international agreements, where nations work together to manage resources or address issues like climate change and security.
