Soccer originated independently in many ancient civilizations, with early games resembling soccer played in China over 3000 years ago. In Europe during the Middle Ages, early forms of soccer grew popular and were often chaotic with no set rules or player limits. The modern game of soccer developed in England during the 19th century, when the first set of rules were established. Soccer is now played on a large grass field with goals at each end, involving two teams of 11 players who use only their feet, body and head to pass and shoot a ball into the opponent's goal.
