Question

Which is the best description of the city of Constantinople at the time of the First Crusade?

Constantinople was a Muslim city that the Crusaders wanted to occupy.
Constantinople was a city where the pope lived and preached the call for the First Crusade.
Constantinople was a city that was neutral during the time of the First Crusade.
Constantinople was a Christian city from which the Crusaders marched on Jerusalem.

Answer 1

Constantinople was a Christian city from which the Crusaders marched on Jerusalem.

It was the capital of the Byzantine (Eastern Orthodox Christian) Empire. Crusader armies passed through and were hosted by Emperor Alexios I Komnenos before moving on through Anatolia toward the Holy Land. The other choices are incorrect: it was not Muslim, the pope lived in Rome (not Constantinople), and the Byzantines were not simply neutral.
