Thailand’s landmark marriage equality bill has been endorsed by the monarchy, making it the first country in Southeast Asia to recognize same-sex marriage.

Thailand’s landmark marriage equality bill was officially written into law Tuesday, allowing same-sex couples to legally wed.

In a victory for LGBTQ+ rights, Thailand became the first Southeast Asian country to legalize same-sex marriage. The bill legalizing same-sex marriage was passed by Parliament earlier this year, and King Maha Vajiralongkorn made it law on Tuesday by providing Royal Assent.
