The work on its preparation began in late 1875 in Thessaloniki. A revolutionary group was created there, that took a decision to organize an anti-Ottoman insurrection. This group consisted of activists of the Association "Bulgarian Dawn".[3] The leader of the group was Dimitar Popgeorgiev - Berovski.
The preparations for the rebellion began in late 1875 in the village of Razlovci, guided by Dimitar Berovski and Stoyan Razlovski. Nedelya Petkova and her daughter sewed the flag of the uprising. It was planned that the rebellion would cover Maleševo, Radoviš, Strumica, Petrich, Melnik and later the Osogovo. After the outbreak of the April Uprising, a number of arrests were made by the Ottoman authorities in late April 1876.[4] Because of this, the revolt broke out prematurely on May 7 (May 19 in Gregorian), in Raslovci. Two revolutionary bands of about 60 people got the village for a short time, and then the rebellion spread in Malеševo and Pijanec. However, the revolt was suppressed, and many of the rebels were killed or arrested. The survivors escaped into the Maleševo Mountains, but no further action was possible.[5]
^At the time of the Russo-Turkish war and in connection with the Berlin Peace Treaty several significant events took place on the local level. The Bulgarian April uprising in 1876, that was the prelude to the Russo-Turkish war, also spread into Macedonia at Razlovtsi in east Macedonia, but the uprising was unsuccessful and soon suppressed by the Ottoman authorities... Macedonian historians naturally challenge the unity of the Bulgarian people. They stress the local character of an uprising...Here we encounter the problem that in many sources the population is called Macedonian Bulgarians. In most cases it is not clear if the words Macedonia/Macedonian have anything else than a regional (as opposed to national) sense.
