6 Sugar Beets •The development of the European beet sugar industry was encouraged by the Napoleonic Wars. In 1807 the British began a blockade of France that prevented the import of sugarcane from the Caribbean. •In 1813 Napoleon instituted a retaliatory embargo. By the end of the wars, over 300 sugar beet mills operated in France and central Europe. •Beet sugar accounts for 30% of the world's sugar production.
