In response to the the U.S. Supreme Court's ruling on June 26, 2015 that the U.S. Constitution guarantees a right to same-sex marriage, OutHistory presents a chronology of documented references to the long history of marriage in U.S. same-sex and transgender history. It stresses the historical diversity and contested quality of marriage relationships, and begins in 1538. The feature is a work in progress, and we hope you will consider contributing to the crowd sourcing process of researching it. OutHistory is asking scholars and the general public to send additional references, including pictures, with as full citations as possible, to outhistory@gmail.com.  If you are teaching a class, and would like to have students work on the timeline as an assignment, we can give you editing privileges for the data base.
