In the southern part rise the Arbuckle mountains (427 m), the Table Hills and further west the Wichita mountains. The north-western part of the state is instead made up of a large plateau, which is part of the Great Plains Region, which extends east of the Rocky Mountains. The average annual temperature of the state is 15 °, 5 and is fairly uniform from place to place: winters are always above freezing (+ 0.5 in January in Beaver, in the north-west section; + 5 °, 5 at Healdton in the south-east section); the very hot summers (26 °, 6 in Beaver, in July; 28 °, 3 in Lehigh); enormous changes in temperature, with very accentuated absolute maximums and minimums.

According to the 1930 census, 16 cities exceeded 10,000, rising to a maximum of 185,389 for Oklahoma City (v.). In 1930 the population was made up as follows: Whites 88.6%; Negroes 7.2%; other races 4.2%; of these, the largest group is made up of the Indians (74,825 in 1920; 92,725 in 1930).

The geographical position and the good environmental and morphological conditions have allowed a magnificent road and rail development: but inland navigation has very little importance. The 465 km railways. in 1880 they rose to about 11,000 in 1931.


The territory bearing this name was formed by Congress in 1834 and used for the use of 5 Indian tribes. Between 1820 and 1851 the federal government entered into a series of treaties with these tribes, assigning a northern strip across the width of the territory (with the exception of the northeast corner) to the Cherokee; this area is always called the Cherokee strip. The southern part, that is, south of the Canadian and Arkansas rivers, belonged to the Choctaws and Chickasans; to the Seminoli the part between the Canadian river and its northern branch (North fork); and at the Creek all the rest up to the Cherokee strip. During the civil war these tribes, who owned slaves, fought on the side of the Confederates, and therefore after the conclusion of the peace the federal government, in 1866, he abrogated the treaties in force on the pretext of redistributing the lands, also attributing them to the emancipated. The vast areas thus obtained were only in a small part allotted to the old tribes and to many other Indian tribes; a huge territory remained that on April 22, 1889, President Harrison opened for colonization by the Whites: at that moment more than 20,000 people were ready at the border to rush towards the possession of the new lands. Following further negotiations with the Indians, in 1904 the whole territory was opened to the Whites. Based on the Dawes Commission report of 1893 and the Curtis Act of 1898, the federal government in 1906 approved the entry into the Union, as a single state, of the Indian Territory and that part which in 1890 had been detached as ”

Given the state’s mineral wealth, many of these Indians are in very flourishing conditions. The capital, which was in Guthrie until 1910, was transported to Oklahoma City in that year. Oklahoma has always been loyal to the Democratic party.
