Gay balls, cross-dressing balls, pansy balls, or drag balls were (depending on the place, time, and type) public or private balls that were celebrated mainly in the first third of the 20th 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, such as Mexico City and New York City.
