Travel back to the 6th century where the history of chess finds its origins in an Indian strategy game called chaturanga, “which translates as “four divisions (of the military)”: infantry, cavalry, elephantry, and chariotry. These forms are represented by the pieces that would evolve into the modern pawn, knight, bishop, and rook, respectively.”

By 1000 AD, the game had become part of courtly education. Chess was used as an allegory for different social classes performing their proper roles, and the pieces were re-interpreted in their new context. At the same time, the Church remained suspicious of games. Moralists cautioned against devoting too much time to them, with chess even being briefly banned in France.

This change accelerated the game’s pace, and as other rules were popularized, treatises analyzing common openings and endgames appeared. Chess theory was born.
