Klemens von Metternich
Klemens Wenzel Nepomuk Lothar, Prince von Metternich-Winneburg zu Beilstein, KOGF (; 15 May 1773 – 11 June 1859) was an Austrian diplomat who was at the center of European affairs for four decades as the Austrian Empire's foreign minister from 1809 and Chancellor from 1821 until the liberal Revolutions of 1848 forced his resignation.
Carl, 3rd Prince of Leiningen
Prince Emich Carl had received the Principality of Leiningen during the German mediatisation ("Reichsdeputationshauptschluss") in 1803, as a compensation for the lost Hardenburg estates in the Palatinate occupied by French revolutionary troops, and took his residence at the secularised Amorbach Abbey. The princely territory, however, soon after passed to the newly established Grand Duchy of Baden, the Kingdom of Bavaria and the Grand Duchy of Hesse. Prince Emich Carl died on 4 July 1814 and Carl succeeded him as third Prince of Leiningen. On 11 July 1818, his widowed mother married Prince Edward, the fourth son of King George III of the United Kingdom, at Kew Palace, Surrey. In 1819, Carl and his younger sister Princess Feodora were taken from Amorbach to London, where their half-sister Princess Victoria of Kent was born on 24 May at Kensington Palace. 
On 13 February 1829, Carl married the Bohemian countess Maria von Klebelsberg (27 March 1806 – 28 October 1880), daughter of Count Maximilian von Klebelsberg and his wife Maria Anna von Turba. They had two sons:Carl had attended a private school in Bern and from 1821 onwards studied law at the University of Göttingen with the jurist Karl Friedrich Eichhorn, then one of the principal authorities on German constitutional law and leading proponent of the German Historical School of jurisprudence. At the British court, his multifaceted interests in art were aroused. From 1828, he had Waldleiningen Castle near Mörschenhardt (named after Waldleiningen in the Palatinate) erected as his private residence, a Romantic complex resembling Neo-Gothic castles in Britain, such as Abbotsford House. Carl was made a Knight of the Order of the Garter in 1837.
