Shatranj is a Persian word that means "king's game." It is a precursor to chess that was played in Persia and India in the 6th century CE. The game was played on a 64-square board with 16 pieces, each piece having its own unique movement. As the game spread, it took on different names in different locations. In Arab countries, it became known as "chess" or "the Persian game." In Spain and Italy, it was called "ajedrez" and "scacchi," respectively. However, no matter the name, shatranj remains an important precursor to modern-day chess, and it continues to be played by enthusiasts around the world.
