Although same-sex relationships were quite common in ancient Greece, Rome, and pagan Celtic societies, severe laws against homosexual behavior emerged once Christianity became the official religion of the Roman Empire. European authorities deemed homosexual acts, referred to as sodomy, as capital crimes, leading them to execute thousands of gay men during waves of persecution over the centuries. Although they less frequently punished lesbian relationships, they still persecuted and executed many women.
For centuries, LGBTQ+ individuals had to live hidden lives due to strong moral and social disapproval from heteronormative societies across Europe. It wasn’t until the modern LGBTQ+ rights movement began in 1969 that significant change started to occur.
Today, LGBTQ+ rights in Europe vary widely by country. Sixteen of the 28 countries worldwide that have legalized same-sex marriage are located in Europe. An additional thirteen European countries have legalized civil unions or other forms of limited recognition for same-sex couples
According to Gallup, several leading European countries are among the most LGBTQ+ friendly in the world. Countries such as the Netherlands, Spain, Portugal, and Denmark rank highly on various lists for their progressive attitudes and policies.
