Rudolf II of Saxe-Wittenberg

Rudolf II (c. 1307–1370), eldest son of Rudolf I, was Elector of Saxony from 1356. He fought at Crécy in 1346, leading the German auxiliaries after John of Bohemia fell, and received a thorn said to be from Christ's Crown of Thorns for Wittenberg's All Saints' Church.

He upheld his electorate against Saxe-Lauenburg claims, while the 1369 award of Lüneburg to his nephew Albert opened the Lüneburg War of Succession. Nearly blind late in life, he died in December 1370 without sons and was succeeded by his brother Wenceslas I.
