Public Life

On Oklahoma Day, some banks and financial institutions may be closed in the state of Oklahoma. Public transit systems run to their normal schedules and stores and other businesses are open as usual. Oklahoma Day is not a public holiday in other parts of the United States.


The area, which is now the state of Oklahoma, has been inhabited since the end of the last ice age. There were permanent communities, such as at the Spiro-mounds from around AD 850. European explorers first visited the area during the 16th century. Following the Indian Removal Act of 1830 and the Indian Intercourse Act of 1834, thousands of Native Americans were removed from their ancestral lands and transported to Oklahoma, even though the area was already occupied by the Osage and Quapaw peoples.

In the middle of the 19th century, ranchers in Texas and Kansas found it difficult to meet the demands for food from the large cities. This lead to pressure to make more land available for farming and, in 1887, the Dawes Act removed control of much of the land in Oklahoma from Native Americans. This land was opened to European settlers from April 22, 1889. The anniversary of this date has become known as Oklahoma Day.


The state flag of Oklahoma consists of a sky blue background with an image of an Osage Nation shield made of buffalo hide. The hide is decorated with six golden brown crosses, which represent stars and seven eagle feathers hang from the shield. The shield is covered by a calumet (peace pipe) and an olive branch. These are symbols of peace between the Native Americans and European settlers in the state.

The word 'Oklahoma' is written in white letters under the shield. Other symbols of Oklahoma include the scissor-tailed flycatcher (a bird), mistletoe (a woody plant that grows on trees), buffalo (an animal), redbud (a tree), Barite rose (a rock) and Indian Blanket (a flower).
