This is a map of the countries Europe colonized, controlled, or influenced between 1500 and 1960. The purple is Europe. The orange countries are ones never under European rule. Almost the entire rest of the map — all the green, blue, and yellow — were dominated by Europe to some extent. “Influenced” is pretty much a euphemism and often not all that different than outright domination.

Max Fisher, writing at Vox, summarizes:

There are only four countries that escaped European colonialism completely. Japan and Korea successfully staved off European domination, in part due to their strength and diplomacy, their isolationist policies, and perhaps their distance. Thailand was spared when the British and French Empires decided to let it remained independent as a buffer between British-controlled Burma and French Indochina…

Then there is Liberia, which European powers spared because the United States backed the Liberian state, which was established in the early 1800s by freed American slaves who had decided to move to Africa.
