The title "Queen Consort of Bulgaria" refers to the wife of the reigning monarch of Bulgaria. Historically, the queen consort played a significant role in the royal court, often involved in social and charitable activities. She was not a ruling monarch but supported her husband, the king, in his duties and responsibilities. The position has been held by various women throughout Bulgaria's history, particularly during the time of the Bulgarian Empire and the Kingdom of Bulgaria. Notable queen consorts include Queen Marie Louise and Queen Giovanna, who contributed to the cultural and political life of the nation during their respective eras.
