Ottoman Empire

Founded in the late 1200s the Ottoman Empire was an imperial state. The empire grew to become one of the largest and most powerful empires in the world. Territory ranged from the Middle-East, all the way to what is now part of modern-day Europe. The Ottoman Empire had an advanced military organization and a centralized political structure, which allowed it to expand so rapidly. The Ottoman Empire also used a system of ambassadors, transactions and relations under the rule of the empire that is often considered one of the origins of cultural diplomacy. After the end of World War I, the Ottoman Empire officially came to an end with the Treaty of Sevres.
