The rules of water polo were originally developed in the mid-nineteenth century in Great Britain by William Wilson.
The modern game originated as a form of rugby football played in rivers and lakes in England and Scotland with a ball constructed of Indian rubber.
This "water rugby" came to be called "water polo" based on the English pronunciation of the Balti word for ball, it means "pulu".
Early play allowed brute strength, wrestling and holding opposing players underwater to recover the ball; the goalie stood outside the playing area and defended the goal by jumping in on any opponent attempting to score by placing the ball on the deck.
By the 1880s, the game evolved that stressed swimming, passing, and scoring by shooting into a goal net; players could only be tackled when holding the ball and could not be taken under water.
To deal with constant changes in rules, in 1888, the London Water Polo League was founded and approved rules to allow team competition, forming the foundation of the present game.
The first English championships were played in 1888.
In 1890, the first international water polo game was played; Scotland defeated England, 4-0.
Over the years, both technical and rule changes affected the character of the game.
In 1928, Hungarian water polo coach Béla Komjádi invented the "air pass," or "dry pass", a technique in which a player directly passes the ball through the air to another player, who receives it without the ball hitting the water.
Previously, players would let the ball drop in the water first and then reach out for it, but the dry pass made the offensive game more dynamic, and contributed to Hungarian dominance of water polo for 60 years.
In 1936, James R. ("Jimmy") Smith, California water polo coach and author of several books on water polo mechanics, developed a water polo ball made with an inflatable bladder and a rubber fabric cover, which improved performance.
The previous leather ball absorbed water and became heavier during the game.
In 1949, rule changes allowed play to continue uninterrupted after a referee whistled an ordinary foul, speeding up play.
In the 1970s, the exclusion foul replaced a point system for major fouls; players guilty of this foul were excluded for a 1 minute penalty and their team forced to play with fewer players.
Possession of the ball was limited to 45 seconds before a scoring attempt.
Time of penalties and possession has been reduced since then.
The direct shot on goal from the seven (7) meter line after a free throw was allowed in 1994, and changed to a five meter throw in 2005. 
In the National Basketball Association, bonus rules in a quarter apply starting with the fifth team foul.
The NBA rules on the team foul penalty are similar to the FIBA version, with three major differences.
Only defensive and loose-ball fouls count towards a team's limit for the team foul penalty.
Offensive fouls do not count towards the team foul penalty.
The team foul penalty applies in a period after a team commits one foul in the final two minutes if the team had not reached the penalty phase in the first ten minutes of that period.
In other words, within any period free throws are awarded starting from the fifth foul OR from the second foul in the last two minutes of the period, whichever comes earlier.
If a game enters overtime, the foul counts are reset to 0, and are similarly reset before each subsequent overtime period.
The penalty phase starts with the 3rd foul in each overtime period rather than five for regulation periods, since overtime periods are so much shorter than regular game periods (five minutes vs. twelve in regulation play).
As is regulation play, two free throws are awarded for non-shooting defensive fouls during the bonus period, and one foul in the final two minutes automatically puts the team in the team foul penalty. 
An ejection is called when a foul is committed when the ball is in no possession.
The player must move to the corner and switch with another player.
The replacement player may not join play until a change of possession, turnover, or another foul is committed.
Should the player be ejected more than three times, the player will be given a red card and will no longer be allowed back for the rest of the game.
Players in the water that acquire a misconduct will be shown a red card and must leave the competition area.
Coaches and players on the bench may be ejected by being awarded a red card. 
Charles (Karlu) Flask was a renowned water polo player of pre-World War II St Julian's ASC.
He was the first Maltese swimmer and water polo player who forced the resignation of the ASA Council in 1936 and of the ASA president in 1937.
Charles Flask, the son of Alfred (the National and St. George's FC goalkeeper of the pre-World War I era) and Rafela née Busuttil was born in Bormla on July 11, 1907.
Though still a child, he often went to help his father, who worked as a boatman at the Grand Harbour, Malta.
During his free time, he would go to Kalkara, Rinella or Bormla wharf to swim with his friends, who soon noted how keen he was in swimming.
At 20 he tried unsuccessfully to set up a water polo team at Marsaskala and Bormla.
Two of St Julian's ASC committee members, Grixti and Vella Agius, contacted him and asked him to join St Julian's ASC.
Though Charles was coming from "the other side" of Malta, the two were aware of his lethal left-handed strike and how strong he was in swimming.
With St Julian's ASC he improved his swimming skills so that in 1932 many were of the opinion that he was one of the finest Maltese water polo players and swimmers.
He successfully played for Pick Malta and St Julian's ASC both locally and abroad.
At the same time he showed his skills as a swimmer, being second to none for various year in the 1930s.
Suffice it to say that he was the first Maltese to swim the 100 yards freestyle in 57 seconds (as timed by Captain Curmi, KOMR).
Unfortunately, he is remembered more for what in the history of water polo is referred to as 'The Charles Flask incident'.
In 1936, Malta was preparing to take part in the Berlin Olympic Games.
As was expected, Charles was called to join the national water polo team but, before the Malta party was formally announced, Flask was dropped from the side.
St Julian's ASC, with players like Flask in its ranks, won 40 out of 42 games.
For the rest of his life he never forgot the harm done to him and, though he continued to play for several years, he always regretted up to his death on May 29, 1978, not being given the possibility to play for the Malta side in the 1936 Olympic Games.
Charles Flask, was a real sportsman.
He practised football, rowing, boxing, cycling and billiard but he was first and foremost a great swimmer and one of the best Maltese water polo players.
Charles Flask was married to late Maria Concetta née Cilia (widow of Tony Delia) and had five sons and two daughters. 
The game clock is stopped when the ball is not 'in play' (between a foul being committed and the free throw being taken, and between a goal being scored and the restart).
As a result, the average quarter lasts around 12 minutes 'real time'.
A team may not have possession of the ball for longer than 30 seconds without shooting for the goal unless an opponent commits an ejection foul.
After 30 seconds, possession passes to the other team.
However, if a team shoots the ball within the allotted time, and regains control of the ball, the shot clock is reset to 30 seconds.
Each team may call 1 one-minute timeout in each period of regulation play, and one timeout if the game goes into overtime.
During game play, only the team in possession of the ball may call a timeout.
