Why the Queen is the most powerful piece: the story of the reform that transformed chess
The answer in brief
The queen has not always been the most powerful piece on the chessboard: in the Indian and Persian versions of the game, the equivalent of the queen moved only one square diagonally, barely more than a pawn. It was a European reform at the end of the 15th century, dubbed "the enraged queen's game" (echecs de la dame enragée) at the time, that gave her her current mobility along ranks, files, and diagonals. This reform also accelerated the pace of the game to such an extent that it completely revolutionized opening theory.
The queen so clearly dominates the chessboard today — more mobile than any other piece, capable of traversing the board in a single move — that it's easy to forget she didn't always have this status. For almost 900 years, the piece occupying that square was one of the weakest in the game, not the strongest.
The Vizier, the Queen's Forgotten Ancestor
In Chaturanga and then Shatranj, the Indian and Persian versions of the game, the square now occupied by the queen was held by a counselor or vizier (firzān). Its mobility was extremely limited: only one square, diagonally only, exactly like a king's move but restricted to one direction. It was one of the least active pieces on the board, far behind the rook or even the knight.
It was only when it migrated to Europe, through the Arab-Muslim world and then medieval Spain, that this piece was renamed "queen" or "dame," probably by analogy with European court games where the king was systematically accompanied by his consort. The name change preceded the change in movement by several centuries.
The Reform That Changed Everything: The "Enraged Queen"
At the end of the 15th century, in Spain and Italy, a reform of the rules gave the queen the ability to move along any rank, file, or diagonal, without distance limits — exactly her current movement. The change was so radical that contemporaries dubbed this new version "enraged queen's chess" (ajedrez de la dama in Spain), in contrast to the much slower "old" game.
The effect on the nature of games was immediate. A piece capable of simultaneously threatening several areas of the board completely changes the pace of an opening: traps become possible from the first moves, which explains why modern opening theory, including the most aggressive ones, could only develop after this reform.

Discover →Why the Queen is Worth Approximately Nine Points
In simplified evaluation scales used to learn how to weigh an exchange, the queen is generally worth nine points, compared to five for a rook, three for a knight or bishop, and just one for a pawn. This figure directly reflects her mobility inherited from the 15th-century reform: she combines the range of the rook (ranks and files) and the bishop (diagonals), which explains why she is worth almost double a rook, which is already considered a heavy piece.
It is precisely this value that makes the promotion of a pawn to a queen so dreaded by the opponent, and which justifies why some premium sets include spare queens in case of multiple promotions during the same game.

The queen's power has a downside well-known to experienced players: bringing her out too early, unprotected, exposes her to attacks from much less valuable pieces. A pawn or a knight threatening the queen forces her to move, losing precious time in development. This is one of the most common mistakes among beginners, who confuse the theoretical power of a piece with the security of its actual position on the board, a principle that applies equally to the knight, whose L-shaped move is explained in the article dedicated to it.
What to remember
The queen is by no means a "naturally" all-powerful piece: she owes it to a specific, dated, and documented reform that transformed an almost immobile advisor into the most mobile piece in the game. This story recalls a more general rule, useful to any player: the value of a piece on the chessboard depends as much on its history and rules as on how it is protected during the game.
Frequently Asked Questions
Has the queen always had this move in chess?
No. In the Indian and Persian versions of the game, the queen's ancestor (a vizier) moved only one square diagonally. Her current movement, unlimited along ranks, files, and diagonals, dates back to a European reform at the end of the 15th century.
Why was this reform called "the enraged queen"?
Because the contrast with the older, much slower version seemed almost violent to players of the time: a piece once almost immobile suddenly became capable of crossing the entire board in one move.
How much is a queen worth compared to other pieces?
In simplified scales used for learning, the queen is worth about nine points, compared to five for a rook, three for a bishop or knight, and one for a pawn. So, she is worth almost double a rook.
Can a pawn really become a second queen?
Yes: when a pawn reaches the last rank, it is obligatorily promoted, most often to a queen since it is the most powerful piece. Nothing prevents having multiple queens on the chessboard at the same time if multiple pawns are promoted during the game.
Why do beginners often lose their queen quickly?
Because they bring her out too early, without protecting her sufficiently, relying on her theoretical power rather than the actual safety of her position. A much less valuable piece, such as a pawn or a knight, is enough to threaten her and make her lose time.
Did the king undergo the same reform as the queen?
No, the king's movement (one square in any direction) has never changed since the game's origins. Only the queen experienced such a radical leap in power during the history of chess.
