The Creek confederacy was based upon a number of tribes speaking the Muskogee language, usually called Creek, but many other tribes were taken into the organization in course of time, most of them speaking related tongues but a few of entirely distinct stocks. From estimates made by early writers it would seem as though the Creek population had increased from about 7000 in 1700 to 20,000 at the time of the removal (1832). This shrunk again after that date so that the Indian Office report of 1919 gives 11,952 “Creeks by blood,” to which must be added 2141 “Seminole by blood,” 585 “Florida Seminole,” and 192 Alabama in Texas. The Seminole and Alabama formerly belonged to the Confederacy. Probably this includes a great many individuals with very little Indian blood, because the Census of 1910 returned only about 9000 all told.
