Input: Passage: A distinct Greek political identity re-emerged in the 11th century in educated circles and became more forceful after the fall of Constantinople to the Crusaders of the Fourth Crusade in 1204, so that when the empire was revived in 1261, it became in many ways a Greek national state. That new notion of nationhood engendered a deep interest in the classical past culminating in the ideas of the Neoplatonist philosopher Gemistus Pletho, who abandoned Christianity. However, it was the combination of Orthodox Christianity with a specifically Greek identity that shaped the Greeks' notion of themselves in the empire's twilight years. The interest in the Classical Greek heritage was complemented by a renewed emphasis on Greek Orthodox identity, which was reinforced in the late Medieval and Ottoman Greeks' links with their fellow Orthodox Christians in the Russian Empire. These were further strengthened following the fall of the Empire of Trebizond in 1461, after which and until the second Russo-Turkish War of 1828-29 hundreds of thousands of Pontic Greeks fled or migrated from the Pontic Alps and Armenian Highlands to southern Russia and the Russian South Caucasus (see also Greeks in Russia, Greeks in Armenia, Greeks in Georgia, and Caucasian Greeks).
Output:
What caused the unsurface of the Grecian monotony in politics?
