In 1889, the
Kansas and Arkansas Valley Railway (later acquired by the
Missouri Pacific Railway) built a line from
Wagoner through the Foyil area onto the
Kansas state line. The area was then just inside the northeastern corner of the Creek Nation in Indian Territory. A post office was established in March 1890 with the name Foyil. It was closed in September 1890 but reopened in April 1891. By 1901, the population was estimated at 100 people. The Dawes Commission had the town platted in 1902, before the Creek allotment. Strip mines began producing coal nearby before statehood in 1907, causing a small boom in population. Inola's population was 405 in 1920. As the coal industry began to decline, so did the town's population. The 1930 census reported only 399 residents. The decline continued through the post
World War II era, reaching 294 in 1950. A turnaround began in the 1950s as residents began commuting to
Tulsa. Inola's population grew to 584 in 1960 and 984 in 1970. The 1980 census showed 1,550 residents, increasing to 1,589 in 2000 and 1,788 in 2010. ==Geography==
