Frederick IV of Meissen and Elector of Saxony (Frederick the Belligerent (the Warlike)) (11 April 1370 – 4 January 1428) was Margrave of Meissen and Elector of Saxony from 1381 until his death. He is not to be confused with his cousin Frederick IV, Landgrave of Thuringia, the son of Balthasar, Landgrave of Thuringia. Frederick the Warlike was never Landgrave of Thuringia.
He was the eldest son of Frederick III, Landgrave of Thuringia, and Catherine of Henneberg. After the death of his uncle William I, Margrave of Meissen in 1407, he governed the Margraviate of Meissen together with his brother William II as well as with his cousin Frederick IV (son of Balthasar), until their possessions were divided in 1410 and 1415.
In the German town war of 1388 he assisted Frederick V of Hohenzollern, burgrave of Nuremberg, and in 1391 did the same for the Teutonic Order against Wladislaus II of Poland. He supported Rupert III, Elector Palatine of the Rhine, in his struggle with King Wenceslaus for the German throne, probably because Wenceslaus refused to fulfill a promise to give him his sister Anna in marriage.
The danger to Germany from the Hussites induced Frederick to ally himself with Emperor Sigismund; and he took a leading part in the war against them, during the earlier years of which he met with considerable success. In the prosecution of this enterprise Frederick spent large sums of money, for which he received various places in Bohemia and elsewhere in pledge from Sigismund, who further rewarded him in 6 January 1423 with the vacant electoral Duchy of Saxony-Wittenberg; and Fredericks formal investiture followed at Ofen on the 1 August 1425. Thus ascended Frederick IV, who called himself Frederick I now, to the duke and elector. Thus spurred to renewed efforts against the Hussites, the elector was endeavouring to rouse the German princes to aid him in prosecuting this war when the Saxon army was almost annihilated at Aussig on the 16 August 1426.
