House of Saxe-Coburg and Gotha-Koháry in the context of "Prince Ludwig August of Saxe-Coburg and Gotha"

The last Bulgarian royal family (Bulgarian: Българско царско семейство, romanized: Balgarsko tsarsko semeystvo) is a line of the Koháry branch of the House of Saxe-Coburg and Gotha, which ruled Bulgaria from 1887 to 1946. The last tsar, Simeon II, became Prime Minister of Bulgaria in 2001 and remained in office until 2005. Members of the royal family claim the titles of Prince (Princess) of Bulgaria and Duke (Duchess) in Saxony, with the style of Royal Highness.

Coburg Peak on Trinity Peninsula in Antarctica is named after the Bulgarian royal house of Saxe-Coburg and Gotha.

Prince August Leopold of Saxe-Coburg and Gotha and Braganza (6 December 1867 – 11 October 1922), known in Brazil as Dom Augusto Leopoldo, was a prince of the Empire of Brazil and of the House of Saxe-Coburg and Gotha-Koháry. He was the second of four sons born to German Prince Ludwig August of Saxe-Coburg and Gotha and Princess Leopoldina of Brazil.

The second grandson of the Emperor Pedro II, the prince was, for some years included among the presumptive heirs to the Imperial Crown of Brazil. Their descendants would form the Saxe-Coburg and Gotha branch of the Imperial House of Brazil.

The Saxe-Coburg and Bragança Branch (Portuguese: Ramo de Saxe-Coburgo e Bragança) is a cadet branch of the Imperial House of Brazil and of the House of Saxe-Coburg and Gotha-Koháry, itself a branch of the House of Saxe-Coburg and Gotha. The house was founded with the marriage of Princess Leopoldina of Brazil to Prince Ludwig August of Saxe-Coburg and Gotha in 1864. Two of the first four princes of the house were recognized as Princes of Brazil due to the apparent infertility of the Princess Imperial, their aunt, which placed them as heirs presumptive to the throne and made their offspring a junior branch of the Imperial House of Brazil, behind the senior branch which is the House of Orléans-Braganza.
