MAP 26.3 Emigration Out of Asia, 1820–1914 As steamships made crossing oceans quicker and more reliable, many people in Asia left their home countries to find new opportunities elsewhere. European imperialism contributed to this flow, especially by recruiting workers for newly established plantations or mines. Many emigrants simply wanted to work a few years to build their savings and planned to return home. Often, however, they ended up staying in their new countries and forming families there.
