Dimitrovist Pioneer Organization "Septemberists"
Dimitrovist Pioneer Organization "Septemberists" (Bulgarian: Димитровска пионерска организация "Септемврийче") was a pioneer movement in Bulgaria. The organization was founded in September 1944. DPO "Septemberists" organized children between 9 and 14 years old. Its day to day affairs were supervised by the Dimitrovist Young Communist League. A 1967 estimate put its membership to about 700 000. There were also an organization called chavdarcheta – these were the youngest children, which later became pioneers. The difference between the two was the distinctive scarf, which was sky-blue in the chavdarcheta movement and red in the pioneri movement.
