This timeline is a collaborative work-in-progress that has had many contributors over a long period of time. Some of the language used and concepts referenced, influenced by colonialism, imperialism, racism, sexism, and anti-LGBTQ+ beliefs and practices, might have been considered offensive or otherwise problematic by the individuals discussed in the historical documents; some might be considered offensive or otherwise problematic by LGBTQ+ people today or in the future. All of this is part of LGBTQ+ history. We welcome new contributions; please contact firstname.lastname@example.org. First published on OutHistory in 2016; last edited in 2020.
