Yes, historical accounts and modern scholarship suggest Alexander the Great likely had intimate relationships with men, particularly his close companion Hephaestion and the eunuch Bagoas, alongside his marriages to women, fitting the fluid sexual norms of ancient Greece where such relationships were common and not labeled as "gay" or "homosexual" as we understand them today. While some ancient sources described deep emotional bonds and physical intimacy with men, the concept of fixed sexual identities (gay/straight) is a modern construct, making it more accurate to say he was likely bisexual or had same-sex relations.
Evidence for same-sex relationships:
Hephaestion: Described as his "lover," "life-partner," and companion from youth, their bond was exceptionally deep, leading to profound grief for Alexander after his death.
Bagoas: An Iranian eunuch with whom Alexander had a publicly acknowledged intimate relationship, even kissing him at a festival.
Ancient sources: Texts mention his attraction to men and his disinterest in women during his youth, with some historians interpreting these accounts as evidence of homosexuality or bisexuality.
Context of ancient sexuality:
Fluidity: Ancient Greek and Macedonian cultures had different views on sexuality, often emphasizing roles (active/passive) rather than fixed orientations, and same-sex relations were accepted, especially between older men and youths, as seen in the Royal Pages system.
Not "Gay" or "Bisexual": These modern labels don't perfectly apply, as the Greeks lacked such terms; relationships with men and women coexisted without contradiction.
Conclusion:
While Alexander had wives and children, strong textual evidence points to significant intimate relationships with men, suggesting a sexual life that included both sexes, fitting within the flexible norms of his time, even if the specifics remain debated by historians.
