Passage: In 1488 Duke Albert III "the bold" of Saxony, the Margrave of Meissen, campaigned to against the rebellious Flanders, aiming to liberate Emperor Maximilian I, who was held prisoner by the citizens of Bruges. As a reward, Maximilian I appointed Albert III governor of the Netherlands and, as compensation for the cost incurred, Albert was appointed in 1498 as hereditary governor of Frisia, with an understanding that he'd have to subdue Frisia by force of arms before he could take up this post. After subduing the Frisians, Albert III rushed to Leipzig to attend the Diet, the Frisians revolted and laid siege to Franeker, where Albert's second son, Henry had taken up the post of governor. Albert rushed back to Frisia and freed Henry. He then conquered Groningen before dying in Emden on 12 September 1500. Henry inherited the post of governor of Frisia. However, the Frisians kept resisting his rule and he resigned on 30 May 1505 in favour of his brother George, in exchange for two districts in the Ore Mountains.
