The Suez Canal, initially built by the French, became a joint British-French project in 1875, as both saw it as vital to maintaining their influence and empires in Asia. In 1882, ongoing civil disturbances in Egypt ("see Urabi Revolt") prompted Britain to intervene, extending a hand to France. France's expansionist Prime Minister Jules Ferry was out of office, and the government was unwilling to send more than an intimidating fleet to the region. Britain established a protectorate, as France had a year earlier in Tunisia, and popular opinion in France later put this action down to duplicity. It was about this time that the two nations established co-ownership of Vanuatu. The Anglo-French Convention of 1882 was also signed to resolve territory disagreements in western Africa.
