The queen and bishop remained relatively weak until between 1475 AD and 1500 AD, probably in Spain (in the kingdom of Valencia), or perhaps Portugal, France or Italy, the queen's and bishop's modern moves started and spread, making chess close to its modern form. The first document showing the Queen (or Dama) moving this way is an allegorical poem written in Catalan in Valencia in the 1470s. This form of chess got such names as "Queen's Chess" or "Mad Queen Chess" (Italian "alla rabiosa" = "with the madwoman"). This led to much more value being attached to the previously minor tactic of pawn promotion. Checkmate became easier and games could now be won in fewer moves. These new rules quickly spread throughout Western Europe and in Spain, with the exception of the rules about stalemate, which were finalized in the early 19th century. The modern move of the queen may have started as an extension of its older ability to once move two squares with jump, diagonally or straight. Marilyn Yalom says that the new move of the queen started in Spain: see history of the queen.
