Hohenlohe-Langenburg () was a German county and later principality in the Holy Roman Empire. It was located in the current northeastern Baden-Württemberg, Germany, around Langenburg. Since the medieval times this small state was ruled by the House of Hohenlohe, counts and since 1764 ruling Princes of the Holy Roman Empire, until 1806. The princely House of Hohenlohe-Langenburg still owns and lives in Langenburg Castle today. History In 1253 the town and castle of Langenburg were inherited by the lords of Hohenlohe, after the lords of Langenburg had become extinct. Despite repeated divisions in the 13th and 15th centuries and a donation to the Teutonic Order of 1219, the House of Hohenlohe was able to form an almost complete territory of which Langenburg was a part. The lordship of Hohenlohe was elevated to the status of a county in 1495. The house often divided its possessions so that different lines emerged and sometimes merged again later. In 1586-1590, the Neuenstein line split into the Langenburg side line under Count Friedrich. Of the protestant branch of Hohenlohe-Neuenstein, which underwent several partitions and inherited the county of Gleichen in Thuringia (with its residence in Ohrdruf) in 1631, the senior line became extinct in 1805, while in 1701 the junior line divided itself into three branches, those of Hohenlohe-Langenburg, Hohenlohe-Ingelfingen and Hohenlohe-Kirchberg. 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. The British royal family therefore still occasionally visit Langenburg and, conversely, the Hohenlohe-Langenburgs are regular guests at the British court. Prince Karl Gustav Wilhelm (1777–1866) of Hohenlohe-Langenburg, who came from a younger branch, founded a Catholic, Bohemian branch at Rothenhaus Castle (today Červený Hrádek Castle in Jirkov, Czech Republic) in the 19th century.
