The Ottoman Empire had been in decline in the years leading up to WWI. It had lost its territories in the Balkans and in North Africa and the Young Turk Revolution of 1908 had forced Sultan Abdul Hamid to restore the constitution, recall Parliament and schedule an election. Following defeat in the war, the Ottoman Empire was partitioned under the terms of the Treaty of Sevres in 1920 and, two years later, the sultanate was abolished and Turkey became a republic under the leadership of Mustafa Kemal Ataturk.
Had WWI not taken place, the Ottoman Empire would have remained in control of a significant part of the Arabian Peninsula (the western edge of what is now Saudi Arabia and most of modern-day Iraq would have fallen within the Empire's boundaries). Assuming that the Ottoman Empire manages to hold onto its Arab lands in the face of possible revolts, there is potential for it to become one of the wealthiest countries in the world once oil reserves are discovered. A present-day Ottoman Empire might be in the same position as Saudi Arabia, Kuwait, the United Arab Emirates and Qatar in terms of national wealth.
