Changes

After 1907, Oklahoma's fortunes did go up and down with the oil industry. The state was severely affected in the Great Depression, as the economy collapsed. This period led to the Dust Bowl, as poor farming practices led to wide-scale soil loss. After the war, Oklahoma led the country in creating artificial lakes to help with water conservation. The economy gradually shifted away from oil and agriculture changed to practice more water and land conservation practices. In recent Supreme Court ruling in July 2020 now has, once again since the early 1890s, has effectively given some greater sovereignty back to Oklahoma native groups. The Five Tribes of the 19th century received a favorable result that gives the jurisdiction to prosecute criminal cases against Native Americans living in eastern Oklahoma. The ruling states that Natives cannot be prosecuted by state or local law enforcement and have to face tribal or federal courts. However, this is likely to have further implications outside of just the courts. This may also have implication on taxes and other government functions, even putting into question of eastern Oklahoma should effectively be returned as areas administered by the Five Tribes. This includes the state capital Tulsa. More likely, however, it may simply open up a different system of governing for eastern Oklahoma's Native American eastern regions, but non-Native Americans who live in the area are likely to still be subject to state and local law.<ref>For more on recent history, see: Baird, W.
