Same-Sex Marriage refers to the legal union between two individuals of the same gender. This type of marriage grants couples the same legal rights and responsibilities as heterosexual couples, including matters related to taxation, inheritance, and healthcare. The recognition of same-sex marriage varies by country and region, with some places fully legalizing it while others maintain prohibitions. The movement for Same-Sex Marriage gained significant momentum in the late 20th and early 21st centuries, driven by advocates for LGBTQ+ rights. Landmark legal cases, such as Obergefell v. Hodges in the United States, played a crucial role in establishing the legality of same-sex marriage in various jurisdictions.
