 Slaveykov sharply criticised those Macedonians espousing such views, as they had never shown a substantial basis for their attitudes, calling them "Macedonists".Nevertheless, those accused of Slaveikov as "Macedonists" were representative of the movement aiming at the construction of the Bulgarian standard literary language primarily on the Macedonian dialects, such as Kuzman Shapkarev, Dimitar Makedonski and Veniamin Machukovski.Another early recorded use of the term "Macedonism" is found in a report by the Serbian politician Stojan Novaković from 1887.
