Lesbian, gay, bisexual, and transgender (LGBT) people in the United States have a long history, including vibrant subcultures and advocacy battles for social and religious acceptance and legal rights. The 1969 Stonewall riots in New York City are often cited as the beginning of the modern gay civil rights era. The AIDS crisis in the 1980s was a large influence on gay communities and activism. In the late 20th century, social acceptance began to increase, and legal rights followed. Military policy was changed in 2011, allowing LGB people to serve openly. Social conservatives briefly had success outlawing same-sex marriage at the state level in the 2000s, but the U.S. Supreme Court legalized same-sex marriage nationwide in 2015. History There are varying accounts of the place LGBT people occupied in pre-Columbian era Native American tribes. In modern parlance, the term Two-Spirit is often used to describe Native American LGBT people. There were (and are) hundreds of different tribes across the US, each with its own culture, thus acknowledgement and acceptance of and social roles for LGBT people varied across tribes. In the reservation era, Christian missionaries and European government agencies denounced homosexuality and gender variance, forcing LGBT people to adopt social roles and dress considered appropriate, such as making males cut their hair and making females wear dresses. Though the violence and intimidation enacted by the church and government were disproportionately directed at Native Americans, both Native and non-Native LGBT people often lived in hiding to avoid being incarcerated or killed because homosexuality was a criminal offense. The first person known to describe himself as a drag queen was William Dorsey Swann, born enslaved in Hancock, Maryland. Swann was the first American on record who pursued legal and political action to defend the LGBTQ community's right to assemble. During the 1880s and 1890s, Swann organized a series of drag balls in Washington, D.C.. Swann was arrested in police raids numerous times, including in the first documented case of arrests for female impersonation in the United States, on April 12, 1888. LGBT acceptance improved slowly in the 19th century and first half of the 20th century. There were more rapid changes with Gay Liberation in the 1960s and HIV/AIDS crisis activism in the 1980s. A number of writers, artists and entertainers publicly acknowledged their homosexuality. In the 1990s, the popular media began including gay characters. Anti-sodomy laws were ruled unconstitutional in 2003,
