The powerful queen, that changed the world, also transformed chess

Queen Isabella, the monarch that unified Spain and sent Christopher Columbus to


discover America, was also the inspiration for the figure of the queen in modern chess.





The Arabs brought chess to Spain when they invaded it in the eighth century,


but it was not until the late fifteenth century; when Queen Isabella was at


the height of her powers, that the queen became the most powerful piece.





In its original form, the equivalent of the queen was male. It was a piece known


in Spanish as alferza, from the Persian, meaning something like vizier or adjutant.


The figure was weak, and its movements limited.





Later, around 1475, when Isabella was crowned queen of Castile, the chess piece


became female, able to move only one square at a time like the king. Not until 1495,


when Isabella was the most powerful woman in Europe, were the present rules of


chess established, where the queen roams freely in all directions on the board.





Chess has always reflected the real world. It was no accident that the appearance of


the first female chess piece, bearing a crown, sword and sceptre, coincided with the


emergence of Queen Isabella, as she astonished Europe with her powers of


leadership, bravery and determination.|||I'm not sure about where you said "where it reflected change according to leadership in modern times", but you can find 9 categories of Chess Strategies at the source given, below.
