By the late 18th century, political and economic changes in Europe were finally beginning to affect Spain and, thus, the Philippines. Important as a stimulus to trade was the gradual elimination of the monopoly enjoyed by the galleon to Acapulco. The last galleon arrived in Manila in 1815, and by the mid-1830s Manila was open to foreign merchants almost without restriction. The demand for Philippine sugar and abaca (hemp) grew apace, and the volume of exports to Europe expanded even further after the completion of the Suez Canal in 1869.
