Tarihin farko

Wasan gasa cuju wani tsohon wasa ƙwallo ne inda ake amfani da ƙafa, a wani fannin yana kama da ƙungiyar ƙwallon ƙafa. It was possibly played around the Han dynasty and early Qin dynasty, based on an attestation in a military manual from around the second to third centuries BC. In one version, gameplay consisted of players passing the ball between teammates without allowing it to touch the ground (much like keepie uppie). In its competitive version, two teams had to pass the ball without it falling, before kicking the ball through a circular hole placed in the middle of the pitch. Unlike association football, the two teams did not interact with each other but instead stayed on opposite sides of the pitch. Cuju has been cited by FIFA as the earliest form of football. The Japanese version of cuju is kemari (蹴鞠), and was developed during the Asuka period. This is known to have been played within the Japanese imperial court in Kyoto from about 600 AD. In kemari, several people stand in a circle and kick a ball to each other, trying not to let the ball drop to the ground. The Silk Road facilitated the transmission of cuju, especially the game popular in the Tang dynasty, the period when the inflatable ball was invented and replaced the stuffed ball.
