this theory was based on were later determined to be flawed. In 1973 homosexuality was declassified as a mental illness in the United Kingdom. In 1986 all references to homosexuality as a psychiatric disorder were removed from the Diagnostic and Statistical Manual of Mental Disorders (DSM) of the American Psychiatric Association. LGBT rights movements During the Sexual Revolution, the different-sex sexual ideal became completely separated from procreation, yet at the same time was distanced from same-sex sexuality. Many people viewed this freeing of different-sex sexuality as leading to more freedom for same-sex sexuality. The Stonewall riots were a series of violent conflicts between New York City police officers and the patrons of the Stonewall Inn, a gay hangout in Greenwich Village. The riot began on Friday, June 27, 1969, during a routine police raid, when trans women and men, gay men, lesbians, street queens, and other street people fought back in the spirit of the civil rights movements of the era. This riot ended on the morning of 28 June, but smaller demonstrations occurred in the neighborhood throughout the remainder of the week. In the aftermath of the riots, many gay rights organizations formed such as the Gay Liberation Front (GLF). A year later the first gay pride march was held to mark the anniversary of the uprising. Historiographic considerations In an 1868 letter to Karl Heinrich Ulrichs, the terms homosexual and heterosexual were coined by Karl-Maria Kertbeny and then published in two pamphlets in 1869. These became the standard terms when used by Richard von Krafft-Ebing in his Psychopathia Sexualis (1886). The term bisexuality was invented in the 20th century as sexual identities became defined by the predominant sex to which people are attracted and thus a label was needed for those who are not predominantly attracted to one sex.

Historical personalities are often described using modern sexual identity terms such as straight, bisexual, gay or queer. Those who favour the practice say that this can highlight such issues as discriminatory historiography by, for example, putting into relief the extent to which same-sex sexual experiences are excluded from biographies of noted
