1814   


In 1813 The Holland departments of the French Empire declared their independence and made the Prince of Orange Sovereign Prince of the United Netherlands. This was a new role for the representatives of the House of Orange. Previously they had been Stadtholders, not sovereigns but chief executives appointed by the sovereign estates of the provinces. At the First Peace of Paris the areas colored grey on the map were placed under the temporary administration of the Allies. Prince William was given the administration, not the sovereignty, over the Belgian departments, on behalf of the allies.

When Napoleon returned from Elba in 1815 and tried to regain his Empire, Prince William proclaimed himself King of the United Netherlands. Napoleon was eventually defeated at Waterloo.
