Same-sex marriage legalization refers to the process of granting legal recognition to marriages between individuals of the same sex. This movement gained significant momentum in the late 20th and early 21st centuries, reflecting broader societal changes regarding LGBTQ+ rights and acceptance. Legalizing same-sex marriage has profound implications for civil rights, social justice, and family law, often highlighting the tension between traditional views on marriage and evolving understandings of love and partnership.
