The New Imperialism (sometimes Neoimperialism or Neo-imperialism) was a period of colonial expansion—and its accompanying ideologies—by the European powers, the United States of America, and the Empire of Japan during the late 19th and early 20th centuries. The period is distinguished by an unprecedented pursuit of overseas territorial acquisitions. At the time, states focused on building their empires with new technological advances and developments, making their territory bigger through conquest, and exploiting their resources.
