Handball originated in Scandinavia and Germany in the late 19th century. It became an Olympic sport starting in 1972. Handball is played on a 40m by 20m court with goals at each end. Teams consist of 7 players - 6 field players and 1 goalkeeper. The main rules are that field players can only use their hands to pass and shoot, while the goalkeeper can use their feet. Common fouls include traveling, double dribbling, and pushing or holding opponents. Teams use different formations for attacking and defending, such as 3-3 in attack and 5-1 in defense.
