However, William's insanity resulted in the appointment of the then 22-year-old Albert as governor (or regent or "ruwaard") of his brother's territories from 1358 onwards. During Albert's regency, affairs ran smoothly and trade improved. Troubles between the two political parties, the "Hoeks" ("Hooks") and "Kabeljauws" ("Cods"), remained barely beneath the surface. William lived for another thirty years. Albert did not formally succeed him until his death in 1388, by which time he had already arranged the marriage of his daughters to a number of Imperial princes and other nobles. The eldest daughter to have children was Margaret; her son Philip III, Duke of Burgundy would ultimately inherit Albert's territories.
