The history of the New England Patriots began when Boston business executive William “Billy” Sullivan and Sullivan Brother Printers, owned by Joseph Sullivan, were awarded the eighth and final franchise of the developing American Football League (AFL) on November 16, 1959. The following winter, locals submitted thousands of ideas for the Boston football team’s official name. On February 20, 1960, Sullivan chose “Boston Patriots”, with “Patriots” referring to those colonists of the Thirteen Colonies who rebelled against British control during the American Revolution and in July 1776 declared the United States of America an independent nation.

“Patriots” as a nickname had been suggested by 74 fans, among them Larry Kepnes. Immediately thereafter, artist Phil Bissell developed the “Pat Patriot” logo.
