Eastern Rome was sacked in 1204 which was the actual blow that jump stated the Western Enlightenment after plundering Eastern Rome for 50 years. https://www.ancient.eu/article/1188/1204-the-sack-of-constan... https://www.britannica.com/place/Byzantine-Empire/Byzantine-... https://historyofislam.com/contents/the-classical-period/con...

The Ottomans did not take over East Rome until the 15th century, where much of the plunder was already gone to the West. https://www.warhistoryonline.com/ancient-history/fallconstan...
