 With the spread of Islam, chess diffused into the Maghreb and then to Andalusian Spain.During the Islamic conquest of India (c. 12th century), some forms came back to India as well, as evidenced in the North Indian term "māt" (mate, derivative from Persian "māt") or the Bengali "borey" (pawn, presumed derived from the Arabic "baidaq").Over the following centuries, chess became popular in Europe, eventually giving rise to modern chess.
