Petra Hristova is a Bulgarian transgender woman, writer and activist whose personal struggle for legal recognition became one of the most significant transgender rights cases in Bulgaria. Born in 1998, she grew up in northern Bulgaria, moving between Veliko Tarnovo, Lyaskovets, Kozarevets and Gorna Oryahovitsa. Her childhood was marked by isolation and bullying, including physical violence, and she has spoken publicly about growing up without the freedom and security that many children take for granted. At the age of twelve, Petra came across an interview with a Bulgarian transgender woman living abroad. It was a turning point. At a time when little information about transgender identities was available in Bulgarian, she began researching the subject herself, often relying on English-language sources to understand feelings she had struggled to name. Education became an important part of Petra's life. She earned a Bachelor's degree in Applied Linguistics, studying English and Korean, followed by a Master's degree in English Philology. She also obtained a professional qualification in organisational psychology. Later, she enrolled in studies in midwifery, inspired by the idea of helping bring new life into the world. Petra began her medical transition after her first year at university and started hormone therapy in September 2015. Finding appropriate medical care proved difficult, as she encountered specialists who lacked experience with, or were unwilling to treat, transgender patients. In January 2022, she underwent gender-affirming surgery at a private clinic in Greece.
