Thailand made history by legalizing same-sex marriage, becoming the first Southeast Asian nation and the third in Asia, following Taiwan and Nepal, to do so.

In the 2019 election which returned Thailand to civilian rule after five years under a military government, a new reformist party called Future Forward, which fully supported equal marriage, did unexpectedly well. They won the third-largest share of seats, revealing a growing hunger for change in Thailand.

The landmark enactment makes Thailand the first in Southeast Asia and third in Asia (after Taiwan and Nepal) to legalize same-sex marriages.
