The Balkans

According to Wikipedia: "Arnold Joseph Toynbee CH (April 14, 1889 – October 22, 1975) was a British historian whose twelve-volume analysis of the rise and fall of civilizations, A Study of History, 1934–1961, was a synthesis of world history, a metahistory based on universal rhythms of rise, flowering and decline, which examined history from a global perspective. A religious outlook permeates the Study and made it especially popular in the United States, for Toynbee rejected Greek humanism, the Enlightenment belief in humanity's essential goodness, and what he considered the "false god" of modern nationalism. Toynbee in the 1918-1950 period was a leading British consultant to the government on international affairs, especially regarding the Middle East."
