Bulgaria hasn't had a monarchy since 1946 when it was abolished following a referendum. The monarchy itself had ceased functioning since a coup d'état in 1944, which saw the Soviet-backed Fatherland Front come to power.
The end of the monarchy in Bulgaria was bloody, with Prince Kiril, a son of former King Ferdinand I, executed alongside leading Bulgarian politicians of the time.
The Bulgarian monarchy dates back to 680, but it was abolished twice beforehand, once following the invasion of the Byzantines and the second time following the invasion of the Ottomans. The most recent branch of the family was the House of Saxe-Coburg and Gotha-Koháry, which has its own links to the Belgian and British royal families.
This branch ruled the eastern European nation between 1861 and 1946, producing three monarchs: Tsar Ferdinand, Tsar Boris and Tsar Simeon.
While they don't rule Bulgaria anymore, the House still exists, so meet its members below…

© HELLO!Tsar Simeon
© David LevensonBorn on 16 June 1937, Simeon was the final Tsar of Bulgaria ruling for just three years between 1943 and 1946. Simeon's rise to the throne was unexpected, with the royal becoming the monarch at the age of six after his father, Tsar Boris, fell ill and died at the age of 49.
Due to his young age, his uncle, Prince Kiril, prime minister Bogdan Filov and General Nikola Mihov were appointed as regents, leading a Regency Council for the young King. All three were executed following a Soviet-backed coup d'état.
On 15 September 1946, the new Communist government called a referendum on the abolishment of the royal family, which was approved by 96% of voters. Despite the referendum actually violating the Bulgarian constitution, the results were accepted and have been implemented ever since.
Following the results of the referendum, the Bulgarian royal family were exiled. The royals initially took up residence in Egypt, before being granted asylum by the military dictatorship of Spain.
Simeon pursued a business career as he grew older, becoming a chairman of the Spanish subsidiary of Thomson. At the age of 18, due to the Bulgarian constitution, he took an oath of servitude to the Bulgarian people.
When Communism fell, Simeon was granted a Bulgarian passport and he returned to the country in 1996, although he remained coy about whether he had any plans to restore the monarchy. On 6 April 2001, he founded a political party, named the National Movement Simeon II, which swept to power in elections held later that year.
Simeon served as prime minister of Bulgaria until 2005, when his party finished second in the election. The party became part of a ruling coalition, with Simeon holding the title of Chairman of the Coalition Council. In the 2009 elections, the party was wiped out and Simeon stood down as its leader.
On 21 January 1962, Simeon walked down the aisle with Spanish aristocrat Margarita Gómez-Acebo y Cejuela. The couple have welcomed five children: Kardam, Kyril, Kubrat, Konstantin-Assen and Kalina.
Margarita Saxe-Coburg-Gotha
© Jeff J MitchellBorn on 6 January 1935 as Margarita Gómez-Acebo y Cejuela, she is the wife of Tsar Simeon, although she never became the Queen of Bulgaria due to the abolition of the monarchy before her marriage to Simeon.
Despite this, Margarita is still sometimes referred to as Tsaritsa Margarita, which would have been her official title.
Margarita was born into an aristocratic Spanish family, with her father being the 4th Marquess of Cortina. However, during the 1936 Spanish civil-war, her parents and maternal grandmother were arrested and executed by Communists.
The Tsaritsa moved around a lot during her early life, including a spell with a family member in France, before moving in with her aunt and uncle and cousins, who included Luis Gómez-Acebo, who later married Spanish royal Infanta Pilar.
On 21 January 1962, she married Tsar Simeon, and the pair now live in his former home, the Vrana Palace. The couple have welcomed five children: Kardam, Kyril, Kubrat, Konstantin-Assen and Kalina.
Princess Marie Louise
© Luc CastelBorn on 13 January 1933, Marie Louise is the older sister of Tsar Simeon and the current head of the House of Saxe-Coburg and Gotha-Koháry. The change came after Simeon changed the primogeniture rules from agnatic to absolute, allowing his older sister to take the reins.
Like her younger brother, Marie Louise was exiled from Bulgaria following the referendum which abolished the monarchy, and she partially grew up in Egypt and Spain.
On 14 February 1957, Marie Louise walked down the aisle with Prince Karl of Leiningen, a member of the deposed Russian royal family and a great-great grandson of Britain's Queen Victoria. The couple welcomed sons Prince Boris (b. 1960) and Prince Hermann (b. 1963), the latter of whom is 173rd in line to the British throne due to his familial links. However, Marie and Karl did not find love and divorced on 4 December 1968 – Karl died on 28 September 1990.
A year after her divorce, Marie Louise found love with Polish citizen Bronisław Chrobok. The couple currently live in New Jersey and are parents to Princess Alexandra (b. 1970) and Prince Pawel (b. 1972)
Alongside her children, Marie Louise is also a grandmother to seven grandchildren.
Prince Kardam

Although the royal was released from hospital in 2009, he suffered a major health setback in 2010 where he was hospitalised again and placed back into an induced coma. He would remain in a coma until he died from a lung infection on 7 April 2015. He was 52 at the time of his death.

Kalina reportedly suffered an accident at the age of eight which resulted in the loss of her two front teeth. In 1999, she aimed to replace the teeth with crowns, but complications led to an infection spreading to her nasal cavity. During a sea trip, the infection worsened resulting the royal needing to undergo facial surgery.
Kalina has proven to be a controversial member of the family with her risqué fashion sense and in 2023 was subjected to an 8-month driving ban after she crashed into another vehicle after consuming alcohol.
The royal also hit headlines due to an incredible jaw-dropping transformation that has seen her become fairly muscular. Giving a fitness tip, she shared: "A bad lifestyle, drinking alcohol, smoking, overeating, and sleeping little, leads to a day with less energy and to poor or premature ageing. Good nutrition, eight hours of sleep, and good training are the keys to a healthy lifestyle and being in shape."
On 26 October 2002, Kalina married Spanish adventurer and UNESCO Goodwill Ambassador Kitín Muñoz. The pair welcomed son Simeon, named after his grandfather, in 2007.
Prince Boris
© NurPhotoBorn on 12 October 1997, Prince Boris is the oldest son of Prince Kardam and Princess Miriam. Following his father's death, and despite his great-aunt being the head of the House of Saxe-Coburg and Gotha-Koháry, Boris is seen as the heir apparent to the defunct Bulgarian throne.
