The Ottoman Empire came to an end,
politically, on August 11, 1840. "Financial mismanagement and incompetence, along with national revolts in the Balkans and eastern Anatolia, the French occupation of Algeria and Tunisia, and the takeover by the British in Egypt and the Italians in Libya, threatened to end the very existence of the empire, let alone its reforms. By this time the Ottoman sultanate was known as the ‘Sick Man of Europe,’ and European diplomacy focused on the so-called EASTERN QUESTION--how to dispose of the Sick Man's territories without upsetting the European balance of power. Abd al-Hamid II, however, rescued the empire, at least temporarily, by reforming the Ottoman financial system, manipulating the rivalries of the European powers, and developing the pan-Islamic and pan-Turkic movements to undermine the empires of his enemies."

The Ottoman Empire was "Sick". It got into a war with Egypt and was left without any real power to solve the problem. It was falling apart. It needed help to solve this war with Egypt. England, Russia, Austria and Prussia came to the rescue. They became the protectorates of the Ottoman Empire on August 11, 1840 when Egypt accepted their ultimatum on that day.
Here we have prophecy again being exactly fulfilled as prophesied. 391 years, 15 days: from July 22, 1449 to August 11, 1840. God is the ruler of the heavens and the earth. He knows what will happen in advance. All we have to do is just sit back and live His righteous, perfect, sinless life, and leave the driving to Him.
However, let me help you to better understand what is going on in the world today between the Muslims and the West. You can see why there is so much hatred for the West by Islam. The Muslims used to be a great empire until the western nations divided it up.
