Saxe-Coburg and Gotha (German: Sachsen-Coburg und Gotha), or Saxe-Coburg-Gotha, was an Ernestine duchy ruled by a branch of the House of Wettin, consisting of territories in the present-day states of Bavaria and Thuringia in Germany. It lasted from 1826 to 1918.
The name Saxe-Coburg-Gotha also refers to the family of the ruling House of Saxe-Coburg and Gotha, which played many varied roles in the dynastic and political history of Europe in the 19th and 20th centuries. In the early part of the 20th century, before the First World War, it was the family of the sovereigns of the United Kingdom, Belgium, Portugal, Bulgaria, and Saxe-Coburg-Gotha. In 1910, the Portuguese king was deposed, and the same thing occurred in Saxe-Coburg-Gotha in 1918 and in Bulgaria in 1946. As of 2015, branches of the family still reign in Belgium, the United Kingdom, and the other Commonwealth realms. The former Tsar of Bulgaria, Simeon II (reigned 1943–46), kept his surname while serving as the Prime Minister of Bulgaria from 2001 to 2005.
Alfred, KG, KT, KP, GCB, GCSI, GCMG, GCIE, GCVO, PC (Alfred Ernest Albert; 6 August 1844 – 30 July 1900) reigned as Duke of Saxe-Coburg and Gotha from 1893 to 1900. He was the second son and fourth child of Queen Victoria of the United Kingdom and Prince Albert of Saxe-Coburg and Gotha. He was known as the Duke of Edinburgh from 1866 until he succeeded his paternal uncle Ernest II as the reigning Duke of Saxe-Coburg and Gotha in the German Empire.
Alfred was born at Windsor Castle to the reigning British monarch, Queen Victoria, and her husband, Prince Albert of Saxe-Coburg and Gotha, the second son of Ernst I, Duke of Saxe-Coburg and Gotha. As a son of the British monarch, he was styled His Royal Highness The Prince Alfred at birth and was second in the line of succession behind his elder brother, The Prince of Wales. He was known to his family as "Affie", after a childhood mispronunciation of the name "Alfred".
Alfred was christened by the Archbishop of Canterbury, William Howley, at the Private Chapel in Windsor Castle on 6 September 1844. His godparents were his mother's first cousin, Prince George of Cambridge (represented by his father, The Duke of Cambridge); his paternal aunt, the Duchess of Saxe-Coburg and Gotha (represented by his maternal grandmother, the Duchess of Kent); and Queen Victoria's half-brother, Carl, Prince of Leiningen (represented by The Duke of Wellington, Conservative Leader in the Lords).
