I am interested in learning more about the history of chess. How did the predecessors of chess look like?

The predecessors of chess date all the way back to the 6th century in India. The earliest chess pieces were made of ivory and had names such as chariots, elephants, horsemen, and foot soldiers. These pieces resembled warring armies and their movements were based on early Indian military strategy. Chess eventually spread to Persia, where it acquired some features of the game played today. The modern chess pieces were eventually standardized in the 15th century, when the game took on the form we are familiar with today.
