Proposition 2 was a referendum for a state constitutional amendment placed on the ballot by the Texas legislature and approved by the voters at the November 8, 2005 general election. The measure added a new provision to the Texas Constitution, Article 1, Section 32, which provides that "Marriage in this state shall consist only of the union of one man and one woman", and "This state or a political subdivision of this state may not create or recognize any legal status identical or similar to marriage." Texas thus became the nineteenth US state to adopt constitutional amendment banning same-sex marriage. It was the most populous state to adopt a constitutional ban on same-sex marriage until California passed its ban in November 2008.
