Middle East to India, Central Asia, and China

The golden age of the Church of the East is generally considered to be the period between the 9th and 14th centuries, when its influence and geographical reach peaked. During this time, it was the world's largest Christian denomination, with communities stretching from the Middle East to China, and its importance was comparable to that of the Catholic Church in the West or the Orthodox Church in the East. The rise of the Ming Dynasty in China in the 15th century resulted in Christianity being banned, leading to the elimination of the Church's presence in the region. Due to these events, most of the Church's scattered communities across Asia were destroyed or forced to abandon their faith, leaving only the Assyrian communities to preserve their heritage.
