𝐆𝐫𝐚𝐧𝐝 𝐌𝐨𝐬𝐪𝐮𝐞 (𝐔𝐥𝐮 𝐂𝐚𝐦𝐢𝐢), 𝐁𝐮𝐫𝐬𝐚 🇹🇷 A popular tradition states that Ghazi Sultan Yildirim Bayezid 1 took an oath before Allah Azzawajal to have 20 mosques built as a form of gratitude if he was able to achieve victory in the Battle of Nicopolis 1396. Later he managed to completely crush the Crusade comprised of over 20 European armies. So instead of building 20 separate mosques, Sultan Bayezid commissioned construction of a Grand Mosque at Bursa with 20 domes. Bursa was the first Ottoman capital. May Allah illumine the grave of Sultan Bayezid. Amin 🤲 #bayezid #Nicopolis #Ottoman #Osmanli #Crusade #Europe #balkan #Christian
