His grandson, Prince MIKLOS [Nicholas] (1765-1833) was born on the 12th of December 1765. He began life as an officer in the guards, subsequently making the grand tour, which first awakened his deep interest in art. He quitted the army for diplomacy after reaching the rank of _Feldzeugmeister_, and was employed as extraordinary ambassador, on special occasions, when he displayed a magnificence extraordinary even for the Esterhazys. He made at Vienna an important collection of paintings and engravings, which came into the possession of the Hungarian Academy at Budapest in 1865. At his summer palace of Kis Marton (Eisenstadt) he erected a monument to Haydn. His immense expenditure on building and the arts involved the family in financial difficulties for two generations. When the French invaded Austria in 1797, he raised a regiment of 1000 men at his own expense. In 1809, when Napoleon invited the Magyars to elect a new king to replace the Habsburgs, overtures were made to Prince Nicholas, who refused the honour and, further, raised a regiment of volunteers in defence of Austrian interests. He died at Como on the 24th of November 1833. His son, Prince PAL ANTAL [Paul Anthony] (1786-1866), entered the diplomatic service. In 1806 he was secretary of the embassy in London, and in 1807 worked with Prince Metternich in the same capacity in Paris. In 1810 he was accredited to the court of Dresden, where he tried in vain to detach Saxony from Napoleon, and in 1814 he accompanied his father on a secret mission to Rome. He took a leading part in all the diplomatic negotiations consequent upon the wars of 1813-1815, especially at the congress of Chatillon, and on the conclusion of peace was, at the express desire of the prince regent, sent as ambassador to London. In 1824 he represented Austria as ambassador extraordinary at the coronation of Charles X., and was the premier Austrian commissioner at the London conferences of 1830-1836. In 1842 he quitted diplomacy for politics and attached himself to "the free-principles party." He was minister for foreign affairs in the first responsible Hungarian ministry (1848), but resigned his post in September because he could see no way of reconciling the court with the nation. The last years of his life were spent in comparative poverty and isolation, as even the Esterhazy-Forchtenstein estates were unequal to the burden of supporting his fabulous extravagance and had to be placed in the hands of curators. The cadet branch of the house of Frakno, the members of which bear the title of count, was divided into three lines by the sons of Ferencz Esterhazy (1641-1683).
