I want to know the answer to the following question:
What was bolstered by the the final downward spiral of the Empire of Trebizond ?
All the background I'm provided with is that "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.". Is that enough to answer the question?
Answer: no
