He elected Liberal ministers, and he was at first in favour of the programme of German unity put forward at Frankfort, but he refused to acknowledge the democratic constitution of the German parliament. This attitude led to the insurrection at Dresden in May 1849, which was suppressed by the help of Prussian troops. From that time onward his reign was tranquil and prosperous. Later Count Beust, leader of the Austrian and feudal party in Saxony, became his principal minister and guided his policy on most occasions. His death occurred accidentally through the upsetting of his carriage near Brennbuehel, between Imst and Wenns in Tirol (August 9, 1854). Frederick Augustus devoted his leisure hours chiefly to the study of botany. He made botanical excursions into different countries, and _Flora Marienbadensis, oder Pflanzen und Gebirgsarten, gesammelt und beschrieben_, written by him, was published at Prague by Kedler, 1837.

Graf von Beust, Aus _drei-viertel Jahrhunderten_ (2 vols., 1887); Flathe, in _Allg. deutsche Biogr._ (J. Hn.) FREDERICK CHARLES (FRIEDRICH KARL NIKOLAUS), PRINCE (1828-1885), Prussian general field marshal, son of Prince Charles of Prussia and grandson of King Frederick William III., was born in Berlin on the 20th of March 1828. He was educated for the army, which he entered on his tenth birthday as second lieutenant in the 14th Foot Guards. He became first lieutenant in 1844, and in 1846 entered the university of Bonn, where he stayed for two years, being accompanied throughout by Major von Roon, afterwards the famous war minister. In 1848 he became a company commander in his regiment, and soon afterwards served in the Schleswig-Holstein War on the staff of Marshal von Wrangel, being present at the battle of Schleswig (April 23, 1848). Later in 1848 he became _Rittmeister_ in the _Garde du Corps_ cavalry regiment, and in 1849 major in the Guard Hussars. In this year the prince took part in the campaign against the Baden insurgents, and was wounded at the action of Wiesenthal while leading a desperate charge against entrenched infantry. After this experience the wild courage of his youth gave place to the unshakable resolution which afterwards characterized the prince's generalship. In 1852 he became colonel, and in 1854 major-general and commander of a cavalry brigade. In this capacity he was brought closely in touch with General von Reyher, the chief of the general staff, and with Moltke. He married, in the same year, Princess Marie Anne of Anhalt. In 1857 he became commander of the 1st Guard Infantry division, but very shortly afterwards, on account of disputes concerned with the training methods then in force, he resigned the appointment.
