The above map, labeled in Romanian, shows the Danubian Principalities. It should be noted that this map depicts borders that were in place before 1821, but most are very similar to those that would be found at the start of the Greek War of Independence. The principalities are surrounded by a green border, while the Ottoman Empire is surrounded by a light red border to the south and east. Bordered in yellow is Hungary, which at the time was a part of the Austrian Empire. The Phanariots, who controlled the Danubian Principalities, were a wealthy and elite group of Greeks from Constantinople, the capital of the Ottoman Empire. These Greeks were vital to the Ottoman government, and often served as rulers in the Danubian Principalities in the Sultan’s stead.
