changing of the guard

The phrase "changing of the guard" refers to the ceremonial process of replacing the old or outgoing guard with a new or incoming guard. It often symbolizes the transfer of authority, responsibility, or power from one individual or group to another. The changing of the guard is commonly associated with military or royal ceremonies, where soldiers or palace guards perform a choreographed routine to mark the shift in duty. This practice is frequently seen at official residences, such as Buckingham Palace in London, with the primary purpose of maintaining traditions and demonstrating a sense of continuity. However, the phrase can also be used metaphorically to describe any significant shift or turnover in leadership or personnel in various contexts, not limited to the military.
