Frederick III, 1831–88, emperor of Germany and king of Prussia (Mar.–June, 1888), son and successor of William I. In 1858 he married Victoria, the princess royal of England, who exerted considerable influence over him. Frederick was a liberal and a patron of art and learning. In the Franco-Prussian War he distinguished himself as a military commander. He was popular, and much good was expected of his reign, but he died of cancer of the throat soon after his accession and was succeeded by his son, William II. His war diary of 1870–71 has been translated into English.
