As the European conquest of Africa unfolded, Portugal played the role of catalyst rather than leader. Hampered by its small size and weakened by several centuries of European warfare, Portugal was the smallest and poorest of Europe's imperial powers by the end of the 19th century. As a result, it was unable to hold on to everything that it claimed, but by playing off the major powers (England, France and Germany) against each other, Portugal managed to expand the territory that it actually controlled by the end of the "Scramble for Africa."
