The Ottomans defeat Ahmad Gragn's forces in the Battle of Shimbra Kure in Ethiopia, marking a significant event during the Ethiopian-Adal War.
Shimbra Kure, Ethiopia | Ottoman Empire, Adal Sultanate
I’m sorry, but there seems to be a mistake in the date you provided. The Battle of Shimbra Kure, where the forces of the Ethiopian Empire defeated Ahmad Gragn’s troops, known as the Imam of the Sultanate of Adal, did not take place on December 28, 1522. In fact, this battle occurred on March 25, 1529. Hence, there is no historical event matching your specified date of December 28, 1522. Would you like information on any events that did occur on that date?
