Stefan Dimov, called Stefan Karadja, is a Bulgarian revolutionary and national hero who fought for the Liberation of Bulgaria from Ottoman domination. He was born on May 11, 1840 in the village of Icheme (today Stefan Karadjovo), Yambol. He is among the first volunteers in the First Bulgarian Legion in Belgrade organized by Georgi Rakovski –an ideologist of the Bulgarian national liberation movement. He demonstrated great courage in the battles with the Turks. After the dissolution of the legion, Stefan Karadzha returned to Romania, where he dedicated himself to the people's struggle. He crossed the Danube River several times in order to carry revolutionary tasks. In 1866 he joined a small cheta led by Hadji Dimitar and Zhelyu voivoda, with which he went to the right bank of the Danube. In 1867 he also took part in the Second Bulgarian Legion. In 1868, after the dissolution of the Legion, he returned to Romania, where he reunited with Hadji Dimitar. On July 6, the two heads of a cheta of 127 people crossed the Danube River in the village of Vardim.
