Batthyanyi. I. Kazmer, count, a Hungarian statesman, born June 4, 1807, died in Paris, July 13, 1854. In early life he passed some time in England, and upon his return to his native country he joined the liberal party, became a member of the Hungarian diet, and in 1848 took an active part in the national war in defence of the southern border. After having officiated as governor of various districts, he became in 1849 minister of foreign affairs under the administration of Kossuth, and subsequently shared Kossuth's exile in Turkey till 1851, when he repaired to Paris. In that year he addressed a series of letters to the London "Times," in which he reflected rather severely upon Kossuth's character as a statesman and patriot. II. Lajos, a member of the same family, born in Presburg in 1809, shot in Pesth by order of the Austrian government, Oct. 6, 1849. He was a cadet in the Austrian army at the age of 16, and afterward travelled extensively, but returned to Hungary to take a part in the reform movement of the time.

He was one of the leaders of the opposition in the diets of 1839-'40 and 1843-'4, and in 1847 was preeminently instrumental in promoting Kossuth's election to the house of deputies. After the revolution of March, 1848, he was prime minister of the national administration, in which capacity he evinced equal patriotism and moderation. When the war was precipitated by the manoeuvres of the court, he resigned and made some fruitless efforts to bring about a reconciliation. At the opening of 1849 he was one of a deputation from the Hungarian diet to make peace overtures to Windischgratz, who with the Austrian army was approaching Buda-Pesth. The Austrian general refused to listen to the proposition, and the seat of the revolutionary government was removed from Pesth to Debreczin. Batthyanyi remained at Pesth, where he was arrested Jan. 8, 1849, and on Oct. 5 following sentenced by a court martial, presided over by Marshal Haynau, to die on the gallows. He stabbed himself with a dagger, and inflicted so many wounds on his neck that he could not be hanged, and accordingly he was shot.

His estates were confiscated, but restored to his family on the restoration of the Hungarian constitution in 1867.
