Ilinden–Preobrazhenie Uprising
The Ilinden–Preobrazhenie Uprising, or simply the Ilinden Uprising of August - October 1903 (, "Ilindensko-Preobrazhensko vastanie"; , "Ilindensko vostanie"; , "Eksegersi tou Ilinden"), was an organized revolt against the Ottoman Empire, which was prepared and carried out by the Internal Macedonian-Adrianople Revolutionary Organization, with the support of the Supreme Macedonian-Adrianople Committee. The name of the uprising refers to "Ilinden", a name for Elijah's day, and to "Preobrazhenie" which means Transfiguration. The revolt lasted from the beginning of August to the end of October and covered a vast territory from the eastern Black Sea coast to the shores of Lake Ohrid.
