Read this: In fact, there was an eighth province, the County of Drenthe, but this area was so poor it was exempt from paying federal taxes and as a consequence was denied representation in the States General. Each province was governed by the Provincial States, the main executive official (though not the official head of state) was a raadspensionaris. In times of war, the stadtholder, who commanded the army, would have more power than the raadspensionaris.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): Who commanded the army?
the stadtholder
