Why did Napoleon remove his brother Louis Bonaparte as king of Holland in 1810?

Napoleon removed his brother, Louis Bonaparte, from the throne of Holland in 1810 primarily because Louis prioritized the interests of his Dutch subjects over the demands of the French Empire.12

For Napoleon, the Kingdom of Holland was a vital component of the Continental System, a blockade intended to cripple Britain by cutting off its continental exports. While Napoleon demanded the vigorous suppression of smuggling, Louis resisted these efforts and refused to subordinate Dutch economic interests to French policy. Louis’s persistent refusal to enforce the blockade effectively led Napoleon to conclude that his brother was an obstacle to his strategic goals. Consequently, the emperor dispatched troops to the Dutch capital, prompting Louis to abdicate and flee, after which Napoleon formally annexed Holland into the French Empire.123
