Was there ever a gay couple that ruled together?

Yes, one historical example of a gay couple that ruled together is the Roman Emperor Hadrian and his companion Antinous. Hadrian, who reigned from 117 to 138 AD, is known for his deep affection for Antinous, who was a young Greek boy. Their relationship was well-documented, and after Antinous's untimely death, Hadrian deified him and built a city in his honor, showcasing the significance of their bond. While their relationship was not a formal partnership in the way modern couples might define it, their connection is one of the most notable in history.
