History

The original game was created hundreds of years ago in North America among the Native Americans who had many versions of the game; some using two sticks (one in each hand) and some that were co-ed - as well as women having their own teams and variations of the sport. One tribe, the Cherokees, called lacrosse "the little brother of war" because of it's military training value. Often teams were made up of hundreds of players encompassing an entire village or tribe at times; with the result that the goals themselves were miles apart and games could last days. Since the average player had little chance of getting close to the ball, they would concentrate on hitting their opponent with their stick, injuring them and taking them out of play. This would evolve later into the cross-checking and sparring that we see not only in lacrosse but hockey as well.

The Six Tribes of the Iroquois, located in what is now southern Ontario and upstate New York, called their version of the game "baggataway" or "tewaraathon". It was much more organized than in most areas of the country. There were 12 to 15 players per team, and the goals were about 120 feet apart. Still, games would go hours at a time and major injuries were common. It was seen as a good forum for young men to prove themselves and for skill to be developed without permanent injuries on each side nor a major confrontation resulting.

There are various stories about how the sport came to be renamed lacrosse. One is that the first Europeans who saw the game being played were French explorers who immediately looked at the hooked stick being used and thought of the crozier used by the Catholic bishops - la crosse, in French. Another much more likely name origin is that the French played a form of field hockey that was called jeu de la crosse (literally, game of the cross) and recognized the Native American version as a variation of their own familiar game.

Early in the 19th century, Europeans in Canada began playing the game in earnest with Montreal's Olympic Club organizing a team in 1844 specifically to play a match against a Native American team. Similar games were played in 1848 and 1851.

However, the first step toward turning lacrosse into a genuinely organized, modern sport came when the Montreal Lacrosse Club, founded in 1856, developed the first written rules. Previously the rules had been passed on by word of mouth and tradition, leading to many disagreements as time went on. Standardization of the rules and equipment made the game more accessible for all the players and mildly safer.

Over the next century lacrosse thrived not only in the Native American culture, but also in the United States and Canada. Many colleges developed their own teams, with New York University and Manhattan College playing the first U.S. intercollegiate game in 1877.

Over the years ice hockey and lacrosse have always been intertwined; with the original rules of ice hockey being patterned after those of lacrosse. Most hockey players in Canada also have been lacrosse players at one time or another; developing their passing and checking skills far away from the ice rink.

This ancient sport has survived centuries of change and development with very little changes to either the equipment or the rules; the only main skill needed being speed and strength. The spread of hockey around the world has also helped spread the sport of lacrosse as teams spring up and a new generation discovers this entertaining and physically challenging sport.

Lacrosse Equipment
The Crosse: The crosse (lacrosse stick) is made of wood, laminated wood or synthetic material, with a shaped net pocket at the end. The crosse must be an overall length of 40 - 42 inches for attack men and midfielders, or 52 - 72 inches for defensemen. The head of the crosse must be 6.5 - 10 inches wide, except a goalie's crosse which may be 10 - 12 inches wide. The pocket of a crosse shall be deemed illegal if the top surface of a lacrosse ball, when placed in the head of the crosse, is below the bottom edge of the side wall.
The Ball: The ball must be made of solid rubber and can be white, yellow or orange. The ball is 7.75 - 8 inches in circumference and 5 - 5.25 ounces.
The Helmet: A protective helmet, equipped with face mask, chin pad and a cupped four point chin strap fastened to all four hookups, must be worn by all men's players. Glove: All players are required to wear protective gloves. The cutting or altering of gloves is prohibited.
Protective Equipment: All players, with the exception of the goalkeeper, must wear shoulder pads. Arm pads and rib pads are also strongly recommended and often required, as are athletic supporters and protective cups for all players. The goalkeeper is required to wear a throat protector and chest protector, in addition to a helmet, mouthpiece and gloves.

Rules

Men's lacrosse is a contact game played by ten players: a goalie, three defensemen, three midfielders and three attack men. The object of the game is to shoot the ball into the opponent's goal. The team scoring the most goals wins.

Each team must keep at least four players, including the goalie, in its defensive half of the field and three in its offensive half. Three players (midfielders) may roam the entire field.

Teams change sides between periods. Each team is permitted two timeouts each half. The team winning the coin toss chooses the end of the field it wants to defend first.

The players take their positions on the field: four in the defensive clearing area, one at the center, two in the wing areas and three in their attack goal area.

A Lacrosse game begins with a face-off. The ball is placed between the sticks of two squatting players at the center of the field. The official blows the whistle to begin play. Each face-off player tries to control the ball. The players in the wing areas can run after the ball when the whistle sounds. The other players must wait until one player has gained possession of the ball, or the ball has crossed a goal area line, before they can release.

Center face-offs are also used at the start of each quarter and after a goal is scored. Field players must use their crosses to pass, catch and run with the ball. Only the goalkeeper may touch the ball with his hands. A player may gain possession of the ball by dislodging it from an opponent's crosse with a stick check. A stick check is the controlled poking and slapping of the stick and gloved hands of the player in possession of the ball.
Body checking is permitted if the opponent has the ball or is within five yards of a loose ball. All body contact must occur from the front or side, above the waist and below the shoulders, and with both hands on the stick. An opponent's crosse may also be stick checked if it is within five yards of a loose ball or ball in the air. Aggressive body checking is discouraged.
If the ball or a player in possession of the ball goes out of bounds, the other team is awarded possession. If the ball goes out of bounds after an unsuccessful shot, the player nearest to the ball when and where it goes out of bounds is awarded possession.
An attacking player cannot enter the crease around the goal, but may reach in with his stick to scoop a loose ball.

Personal & Technical Fouls
There are personal fouls and technical fouls in a lacrosse game. The penalty for a personal foul results in a one to three minute suspension from play and possession to the team that was fouled. Players with five personal fouls are ejected from the game. The penalty for a technical foul is a thirty-second suspension if a team is in possession of the ball when the foul is committed, or possession of the ball to the team that was fouled if there was no possession when the foul was committed.
