Gay balls, cross dressing balls or drag balls, depending on the place, time, and type, were public or private balls, celebrated mainly on the first third of the twentieth century, where cross dressing and ballroom dancing with same sex partners was allowed. By the 1900s, the balls had become important cultural events for gays and lesbians, even attracting tourists. Their golden age was during the Interwar period, mainly in Berlin and Paris, even though they could be found in many big cities in Europe and the Americas.
By the end of the 17th century, a gay subculture is documented in Europe, with their cruising areas, their bars, their parties and balls, their cross-dressers, and their own slang. Scholars like Randolph Trumbach consider it is the moment when gay subculture appears in Europe. On the contrary, historian Rictor Norton considers unlikely that such a subculture would appear fully formed, and thinks that it was actually the increase in surveillance and police procedures that brought to the surface an underground culture that had not been visible up to that moment.
The archives of the Portuguese Inquisition in Lisbon preserve information of the so-called "danças dos fanchonos" from the beginning of the 17 century. About 1620, the "fachonos", the baroque equivalent of modern drag queens, organized big parties in the Gaia Lisboa, the gay Lisbon. These itinerant celebrations, called "escarramão", or "esparramão", used to include pantomimes with racy scenes, where some of the participants were dressed as women, and other as men. His Majesty's High Court in Mexico City discovered in 1656 a similar case, when Juan Correa, an old man, over 70 years old, confessed that he had been committing the unspeakable vice since his childhood. Correa's house, in the outskirts of the city, had been used as a meeting point to celebrate balls, where many men dressed as women.
