like in the April Uprising. In accordance with the Constitution, the first Central Revolutionary Committee was formed in the summer of 1894, under the chairmanship of Hristo Tatarchev. 1894 to 1900 In the summer of 1894 in Negotino, he organized the first local revolutionary committee, and soon after with the cooperation of Pere Toshev, the first district committee in the city of Štip. Gruev visited the cities of Resen, Ohrid, and Struga as well, and found the local population to be accepting his organization's revolutionary ideas very well. He remained a teacher in Štip during the academic year 1894–1895. In the fall of 1895 Gotse Delchev arrived in Štip with the idea of laying the foundations of a revolutionary movement seeking autonomy for Macedonia and Adrianople Thrace. Gruev and Delchev met for the first time and shared their ideas there. Gruev introduced Delchev to the plan already outlined by the Central Committee of Thessaloniki.
