Content:  College Football Data Warehouse (CFBDW) is an online resource and database that has collected and researched information on college football and national championship selections. It provides a comprehensive list of national championship selectors and has itself recognized selectors that it has deemed to be the most acceptable throughout history. These include the National Championship Foundation (1869–1882), the Helms Athletic Foundation (1883–1935), the College Football Researchers Association (1919–1935), the Associated Press Poll (1936–2015), and the Coaches Poll (1950–2015). From its research, it has compiled a list of Recognized National Championships for each season. Some years include recognition of multiple teams for a particular season. Please note that the CFBDW list of Recognized Champions does not confer any additional legitimacy to the titles. In this regard, some universities claim championships not recognized by CFBDW or do not claim championships that are recognized by CFBDW. Please consult the above table of National championship claims by school or individual team articles and websites for possible additional or alternative national championship claims. Below is a list of all of the CFBDW recognized national championships from 1869 to 2015.
