Throne

A throne is a chair, often raised and covered, occupied by a personage of importance, like the King & Queen or Baron & Baroness, during court or feasts.

Symbolically it represents the office and rank of those who sit upon it. Hence, it is used in English as a metaphorical term for the same:

For example,

ascended the throne = was crowned/became monarch

relinquished the throne = abdicated

won the throne = became monarch through election or battle

In the some SCA kingdoms, it is common practice to acknowledge the presence of royalty when passing by their throne, even if they are not sitting in it. This is done by reverencing or bowing the head towards the throne. (This is a classic example of InterKingdom Anthropology).
