There can be no doubt that Turkish intervention in the First World War was the worst decision ever made by the Ottoman Empire. An empire that had withstood storm. And stress from within and without for more than 600 years was ruined beyond repair in less than four. Here was a country which had dominated the cross roads of the world, the most lucrative trade routes. They had ruled all of north Africa and much of southern Europe for centuries, brought down by choosing the losing side in the First World War.
The Ottoman Empire did not collapse immediately as the war ended like Austria or Germany. Nor did it come down during the war like Russia but although it may not get the attention of the German, Austrian and Russian Empires falling. it was really even more of an historic event. The Ottoman Empire had existed long before the first Hapsburg ever achieved imperial status. Long before the Prussians ever had a country of their own. And long before the Romanov dynasty came to power in Russia.
