Ahakoa he mema ia o te rōpū kāwanatanga o te People's Bloc o Nikola Mushanov, he tino kaiwhaiwhai a Tsankov i a Adolf Hitler, nā reira i whakatūria ai e ia te NSM hei tuku i tētahi putanga o te Nacism. I kauwhau te rōpū i tōna ake ariā o te 'iwi pāpori' e ai ki a Tsankov ko te tautoko i tētahi uniana kaimahi ā-motu ki te pakanga akomanga. Kaore i kitea e te roopu i a ia ano te manakohia (ahakoa he rongonui ki nga taiohi taone nui), ahakoa i awhina tona hanganga ki te whakatere i te hinganga o te kawanatanga whakakotahitanga. I whai ake te roopu i te tau 1934 i te wa i wehe atu ai etahi o nga mema o Zveno ki te whakauru atu ki etahi atu roopu, tae atu ki te NSM. I whakakorehia te rōpū i muri i te coup d'état o 1934
pērā ki ētahi atu rōpū tōrangapū.
