Antwerp's potential as a seaport was recognized by Napoleon Bonaparte and he ordered the construction of Antwerp's first lock and dock in 1811. Called the Bonaparte Dock, it was joined by a second dock - called the Willem Dock after the Dutch King - in 1813. When the Belgian Revolution broke out in 1830, there was a well-founded fear that the Dutch would blockade the Scheldt again but, in the event, they contented themselves with levying a stiff toll. Fortunately, the young Belgium had friends in Britain and particularly in the person of Lord Palmerston, who believed the existence of Belgium would be beneficial to Britain, and that, in consequence, it was important to make sure that the newly born state was economically viable.
