The title "Princess of Bulgaria" refers to female members of the royal family in the historical context of the Bulgarian monarchy. Bulgaria has had several princesses throughout its history, particularly during the periods of the First and Second Bulgarian Empires. These princesses often played significant roles in political alliances through marriage and were influential in cultural and social matters. The last reigning monarch of Bulgaria was King Simeon II, who became king as a child in 1943. After the abolition of the monarchy in 1946, the royal family, including princesses, lived in exile. Today, the descendants of the royal family are involved in various charitable activities and cultural preservation efforts.
