CFB imperialism, also called the college football imperialism map, the imperial map or the empires map, is a game fans play on top of the real season. Every county in the United States starts with the FBS program whose stadium is nearest. When a game goes final, the winner takes all the land the loser holds, so one upset can hand a mid-major half the country, and a team that loses everything can only get back on the map by beating someone who has land. The game was created on r/CFB by u/nbingham196 in 2017; fans there have traded weekly imperialism maps ever since, and SB Nation ran it as the College Football Empires Map in 2018. This site plays it automatically from the official results: the 2026 map refreshes every morning in season, and the timeline above replays every battle in kickoff order.
Beyond the live season, the site has every season since 1869, separate FCS, Division II and Division III imperialism maps, and a coaching-carousel map where land carries over from one season to the next.
The same results feed the records (largest empires, biggest conquests, wildest upsets), a history for every team that ever held land and a career map for every head coach. The rules explain the seeding, raids and data.
