The event marked a decisive step toward totalitarian rule in the Third Reich.

The U.S. Supreme Court rules in Bowers v. Hardwick that states can outlaw homosexual acts between consenting adults.
In Bowers v. Hardwick (1986), the U.S. Supreme Court upheld a Georgia law criminalizing consensual homosexual acts between adults.
On June 30, 1986, the Supreme Court ruled 5–4 that the Constitution did not protect the right to privacy in private consensual homosexual conduct. Justice Byron White’s majority opinion deferred to states’ rights to legislate morality. The decision was immediately condemned by LGBTQ activists and civil liberties groups as a profound setback. Bowers v. Hardwick galvanized the gay rights movement, leading to increased advocacy and eventual legal reforms. Nearly two decades later, the Court overturned Bowers in 2003’s Lawrence v. Texas, establishing broader privacy protections.
