Europeans began to seek an all-water, oceanic route to South and East Asia. The nations of western Europe launched a Crusade to retake control of the trade routes from the Ottomans.

European merchants objected to paying taxes to the Ottomans and created overland routes to India and East Asia that bypassed Ottoman-controlled lands.
