In 1905 he began publishing predominantly articles, written from a Bulgarian nationalist perspective in the IMARO-affiliated press. During the First World War he became a member of the local parliament in Bessarabia as a representative of the Bulgarian minority there. Misirkov reverted to Macedonian nationalism for a short in 1919. During the 1920s his views changed again, and he encouraged the Macedonian Slavs to adopt a Bulgarian national identity. Misirkov died in 1926 and was buried in the graveyards in Sofia with the financial support from the Ministry of Education, as a honoured Bulgarian educator.
