Charles IV of France
Charles resurfaces as a royal name in Germany with Charles IV, Holy Roman Emperor (1316–1378, counted as "the fourth" after Charlemagne, Charles the Bald and Charles the Fat) and in France with Charles IV of France (1294–1328, "the fourth" after Charlemagne, Charles the Bald and Charles the Simple), and becomes comparatively widespread in the Late Middle Ages (Charles I, Duke of Savoy, Charles III, Duke of Savoy).
