Devlet-î Aliyye-i Osmaniyye The Ottoman Empire The Ottoman Empire was established as a Beylik in 1299. In 1453, with the Conquest of Constantinople by Mehmet the Conqueror, it became an empire. At the beginning of the 17th century, it entered a period of stagnation and began to lose its power. Meanwhile, the Russian threat began to grow in the North. After the Church Crisis in the Ottoman Empire, Russia's ambassador in Istanbul, Alexander, left Istanbul on May 19, 1853, after his requests were rejected. The Russian armies began to invade Wallachia and Moldavia on June 22, 1853, without even declaring war. https://www.roblox.com/groups/10781217/Ordu-y-H-mayun Join Comns And Ordu Group for Enlist in Ottoman Army
