Gay balls, cross dressing balls or drag balls, depending on the place, time, and type, were public or private balls, celebrated mainly in 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 such as Mexico City and New York City.
