Great Schism

İstanbul, Turkey

The Great Schism was the break of communion which occurred in the 11th century between the Catholic Church and Eastern Orthodox Church. Immediately following the schism, it is estimated that Eastern Christianity comprised a slim majority of Christians worldwide, with the majority of remaining Christians being Catholic.

As a result, the trading ties that Yaroslav had cultivated declined - the Latin world saw the Rus as heretics.
