The 34th: The Story of Marriage Equality in Ireland is an Irish documentary film by Linda Cullen and Vanessa Gildea. The film tells the story of the people who formed Marriage Equality in Ireland, and explores the events that led to the Thirty-fourth Amendment of the Constitution (Marriage Equality) Act 2015 (previously bill no. 5 of 2015), which amended the Constitution of Ireland to permit marriage to be contracted by two persons without distinction as to their sex.
