Which country was the first to legalise same-sex marriage as a result of a referendum?

Question

Who became the first woman to serve as a Member of Parliament in the British House of Commons, as the result of a by-election in 1919?

Answer 1

Ireland
Ireland held the referendum and then, with 62% approval, legalised same-sex marriage in 2015. Same-sex unions and marriages were accepted, indeed common, for thousands of years and in many parts of the world until Christianity became a dominant influence. Increasingly since 1970 they were again recognised in several countries in a purely civil capacity, as also increasingly were marriages (the first country to legalise them being the Netherlands in 2000), but Ireland was the first to put it to a referendum.
