Lawrence v. Texas was a landmark Supreme Court case decided in 2003 that invalidated laws prohibiting consensual homosexual activity. The ruling was significant because it struck down a Texas law that criminalized same-sex intimacy, reaffirming the right to privacy for individuals and advancing the fight for LGBTQ+ rights in the United States. This case marked a turning point in the legal landscape for gay rights, particularly following the Stonewall Riots, which highlighted the struggle against discrimination and the quest for equality.
