Chess originated in India over 1500 years ago and has evolved significantly since then. The earliest form was called chaturanga and represented Indian military divisions. It later spread to Persia, Arabia, and Europe. The modern game developed in 15th century Europe with standardized rules and pieces. The objective is to checkmate the opponent's king. There are also draws by stalemate or the 50-move rule. Famous chess players who demonstrated great skill include Paul Morphy, Mikhail Botvinnik, and Bobby Fischer.
