When did kansas become a state?

In 1967, the Tennessee public schools were threatened with another lawsuit over the Butler Act's constitutionality, and, fearing public reprisal, Tennessee's legislature repealed the Butler Act. In the following year, 1968, the Supreme Court of the United States ruled in Epperson v. Arkansas that Arkansas's law prohibiting the teaching of evolution was in violation of the First Amendment. The Supreme Court held that the Establishment Clause prohibits the state from advancing any religion, and determined that the Arkansas law which allowed the teaching of creation while disallowing the teaching of evolution advanced a religion, and was therefore in violation of the 1st amendment Establishment clause. This holding reflected a broader understanding of the Establishment Clause: instead of just prohibiting laws that established a state religion, the Clause was interpreted to prohibit laws that furthered religion. Opponents, pointing to the previous decision, argued that this was judicial activism.
