A common folk etymology attributes the name to the Roman numeral for four (IV), asserting that there was such a sports league originally with four members. The "Morris Dictionary of Word and Phrase Origins" helped to perpetuate this belief. The supposed "IV League" was formed over a century ago and consisted of Harvard, Yale, Princeton, and a fourth school that varies depending on who is telling the story. However, it is clear that Harvard, Princeton, Yale and Columbia met on November 23, 1876, at the so-called Massasoit Convention to decide on uniform rules for the emerging game of American football, which rapidly spread.
