Aspect of sports history
The early history of American football can be traced to early versions of rugby football and association football. Both games have their origin in varieties of football played in Britain in the mid–19th century, in which a football is kicked at a goal or run over a line, which in turn were based on the varieties of English public school football games.
American football resulted from several major divergences from association football and rugby football, most notably the rule changes instituted by Walter Camp, a Yale University and Hopkins School graduate considered to be the "father of gridiron football". Among these important changes were the introduction of the line of scrimmage, of down-and-distance rules and of the legalization of interference.
In the late nineteenth and early twentieth centuries, gameplay developments by college coaches such as Eddie Cochems, Amos Alonzo Stagg, Parke H. Davis, Knute Rockne, John Heisman, and Glenn "Pop" Warner helped take advantage of the newly introduced forward pass. The popularity of college football grew in the United States for the first half of the 20th century. Bowl games, a college football tradition, attracted a national audience for college teams. Boosted by fierce rivalries and colorful traditions, college football still holds widespread appeal in the United States.
The origin of professional football can be traced back to 1892, with Pudge Heffelfinger's $500 contract to play in a game for the Allegheny Athletic Association against the Pittsburgh Athletic Club. In 1920 the American Professional Football Association was formed. This league changed its name to the National Football League (NFL) two years later, and eventually became the major league of American football. Initially a sport of Midwestern industrial towns, professional football eventually became a national phenomenon.

History of American football before 1869.
Prehistory of American football.
In 1911, influential American football historian Parke H. Davis wrote an early history of the game of football, tracing the sport's origins to ancient times:
 ;templatestyles src="Template:Blockquote/styles.css" / ;abundant evidence may be marshalled to prove that this is the oldest outdoor game in existence. In the 22nd chapter of Isaiah is found the verse, "He will turn and toss thee like a ball." This allusion, slight as it may be, is sufficient unto the antiquary to indicate that some sort of game with a ball existed as early as 750 years before the Christian era, the epoch customarily assigned to the Book of Isaiah. A more specific allusion of the same period, however, is the passage in the Sixth Book of the Odyssey of Homer familiar to all school boys: "Then having bathed and anointed well with oil they took their midday meal upon the river's banks and anon when satisfied with food they played a game of ball."
Forms of traditional football have been played throughout Europe and beyond since antiquity. Many of these involved handling of the ball, and scrummage-like formations. Several of the oldest examples of football-like games include the Greek game of Episkyros and the Roman game of Harpastum. Over time many countries across the world have also developed their own national football-like games. For example, New Zealand had Kī-o-rahi, Australia marn grook, Japan kemari, China cuju, Georgia lelo burti, the Scottish Borders Jeddart Ba' and Cornwall Cornish hurling, Central Italy Calcio Fiorentino, South Wales cnapan, East Anglia Campball and Ireland had caid, which an ancestor of Gaelic football.
There is also one reference to ball games being played in southern Britain prior to the Norman Conquest. In the ninth century Nennius's "Historia Britonum" tells that a group of boys were playing at ball ("pilae ludus"). The origin of this account is either southern England or Wales. References to a ball game played in northern France known as "La Soule" or "Choule", in which the ball was propelled by hands, feet, and sticks, date from the 12th century.
These archaic forms of football, typically classified as mob football, would be played between neighbouring towns and villages, involving an unlimited number of players on opposing teams, who would clash in a heaving mass of people struggling to drag an inflated pig's bladder by any means possible to markers at each end of a town. By some accounts, in some such events any means could be used to move the ball towards the goal, as long as it did not lead to manslaughter or murder. Sometimes instead of markers, the teams would attempt to kick the bladder into the balcony of the opponents' church. A legend that these games in England evolved from a more ancient and bloody ritual of kicking the "Dane's head" is unlikely to be true.
Few images of medieval football survive. One engraving from the early fourteenth century at Gloucester Cathedral, England, clearly shows two young men running vigorously towards each other with a ball in mid-air between them. There is a hint that the players may be using their hands to strike the ball. A second medieval image in the British Museum, London clearly shows a group of men with a large ball on the ground. The ball clearly has a seam where leather has been sewn together. It is unclear exactly what is happening in this set of three images, although the last image appears to show a man with a broken arm. It is likely that this image highlights the dangers of some medieval football games.
Most of the very early references to the game speak simply of "ball play" or "playing at ball". This reinforces the idea that the games played at the time did not necessarily involve a ball being kicked.
The first detailed description of what was almost certainly football in England was given by William FitzStephen in about 1174–1183. He described the activities of London youths during the annual festival of Shrove Tuesday:
 ;templatestyles src="Template:Blockquote/styles.css" / ;After lunch all the youth of the city go out into the fields to take part in a ball game. The students of each school have their own ball; the workers from each city craft are also carrying their balls. Older citizens, fathers, and wealthy citizens come on horseback to watch their juniors competing, and to relive their own youth vicariously: you can see their inner passions aroused as they watch the action and get caught up in the fun being had by the carefree adolescents.
Numerous attempts were made to ban football games, particularly the most rowdy and disruptive forms. This was especially the case in England, and in other parts of Europe, during the Middle Ages and early modern period. Between 1324 and 1667, in England alone, football was banned by more than 30 royal and local laws. The need to repeatedly proclaim such laws demonstrated the difficulty in enforcing bans on popular games. King Edward II was so troubled by the unruliness of football in London that, on April 13, 1314, he issued a proclamation banning it:
 ;templatestyles src="Template:Blockquote/styles.css" / ;Forasmuch as there is great noise in the city caused by hustling over large balls from which many evils may arise which God forbid; we command and forbid, on behalf of the King, on pain of imprisonment, such game to be used in the city in the future.
In 1531, Sir Thomas Elyot wrote that:
 ;templatestyles src="Template:Blockquote/styles.css" / ;in like wise foote balle, wherin is nothinge but beastly furie and exstreme violence.
These antiquated games went into sharp decline in the 19th century when the Highway Act 1835 was passed banning the playing of football on public highways. Antithetical to social change this anachronism of football continued to be played in some parts of the United Kingdom. These games still survive in a number of towns notably the Ba game played at Christmas and New Year at Kirkwall in the Orkney Islands Scotland, Uppies and Downies over Easter at Workington in Cumbria and the Royal Shrovetide Football Match on Shrove Tuesday and Ash Wednesday at Ashbourne in Derbyshire, England.
Football in America.
In 1586, men from a ship commanded by an English explorer named John Davis, went ashore to play a form of football with Inuit (Eskimo) people in Greenland. There are later accounts of an Inuit game played on ice, called "Aqsaqtuk". Each match began with two teams facing each other in parallel lines, before attempting to kick the ball through each other team's line and then at a goal. In 1610, William Strachey, an English colonist at Jamestown, Virginia recorded a game played by Native Americans, called "Pahsaheman".
Although there are mentions of Native Americans playing games, modern American football has its origins in the traditional football games played in the cities, villages and schools of Europe for many centuries before America was settled by Europeans. Early games appear to have had much in common with the traditional "mob football" played in England. The games remained largely unorganized until the 19th century, when intramural games of football began to be played on college campuses. Each school played its own variety of football. Princeton University students played a game called "ballown" as early as 1820.
A Harvard tradition known as "Bloody Monday" began in 1827, which consisted of a mass ballgame between the freshman and sophomore classes. In 1860, both the town police and the college authorities agreed the Bloody Monday had to go. The Harvard students responded by going into mourning for a mock figure called "Football Fightum", for whom they conducted funeral rites. The authorities held firm and it was a dozen years before football was once again played at Harvard. Dartmouth played its own version called "Old division football", the rules of which were first published in 1871, though the game dates to as early as the 1830s.
All of these games, and others, shared certain commonalities. They remained largely "mob" style games, with huge numbers of players attempting to advance the ball into a goal area, often by any means necessary. Rules were simple, violence and injury were common. The violence of these mob-style games led to widespread protests and a decision to abandon them. Yale, under pressure from the city of New Haven, banned the play of all forms of football in 1860.
The "Boston game".
While the game was banned in colleges, it was becoming popular in numerous east coast prep schools. In the 1860s, manufactured inflatable balls were introduced through the innovations of shoemaker Richard Lindon. These were much more regular in shape than the handmade balls of earlier times, making kicking and carrying easier. Two general types of football had evolved by this time: "kicking" games (like the game played at Cambridge University) which later served as the basis for the rules of the Football Association (soccer) in 1863, and "running" (or "carrying") games, which later served as the basis for the "laws" laid down by the Rugby Football Union in 1871. A hybrid of the two, known as the "Boston game", was already played by a team called the Oneida Football Club. The club, considered by some historians as the first formal football club in the United States, was formed in 1862 by graduates of Boston's elite preparatory schools. They played mostly among themselves, though they organized a team of non-members to play a game in November 1863, which the Oneidas won easily. The game caught the attention of the press, and "the Boston game" continued to spread throughout the 1860s. Oneida, from 1862 to 1865, reportedly never lost a game or even gave up a single point.
The game began to return to college campuses by the late 1860s. Yale, Princeton, Rutgers University, and Brown University began playing the popular "kicking" game during this time. In 1867, Princeton used rules based on those of the London Football Association. A "running game", resembling rugby football, was taken up by the Montreal Football Club in Canada in 1868.
Early history of intercollegiate football (1869–1932).
American football historian Parke H. Davis described the period between 1869 and 1875 as the 'Pioneer Period'; the years 1876–93 he called the 'Period of the American Intercollegiate Football Association'; and the years 1894–1933 he dubbed the 'Period of Rules Committees and Conferences'.
Pioneer period (1869–1875).
Rutgers–Princeton (1869).
On November 6, 1869, Rutgers University faced Princeton University (then known as the College of New Jersey) in a game that was played with a round ball and used a set of rules suggested by Rutgers captain William J. Leggett, based on London's The Football Association's first set of rules,
