Count of Hohenlohe-Langenburg

Hohenlohe-Langenburg was a German county of northeastern Baden-Württemberg, Germany, located around Langenburg. Hohenlohe-Neuenstein was partitioned into it, Hohenlohe-Ingelfingen and Hohenlohe-Kirchberg in 1701. Hohenlohe-Langenburg was raised from a county to a principality in 1701, and was mediatised to Württemberg in 1806.

The House of Hohenlohe-Langenburg remained Protestant, and has remained closely related to Europe's Protestant ruling dynasties. Queen Adelaide of the United Kingdom was a Hohenlohe-Langenburg on her mother's side, and her cousin, Prince Ernst, married in 1828 Feodora of Leiningen, the half-sister of the future Queen Victoria. In 1896, Feodora's grandson, another Prince Ernst, married Victoria's granddaughter, Princess Alexandra of Edinburgh and Saxe-Coburg-Gotha. Prince Gottfried (1897-1960) was married in 1931 to his second cousin once removed, Princess Margarita of Greece and Denmark (1905–1981). She was the eldest daughter of Prince Andrew of Greece and Denmark and his wife Princess Alice of Battenberg, and sister of Prince Philip, Duke of Edinburgh.
