From exclusion to establishment: Organizational birthmarks and imprinting within populist parties.

This paper bridges literature on political parties and organizational studies by providing a new theoretical lens on political party developments. There has been growing scholarly interest in populist parties and the issues that serve as the raison d'être for their political platform. While the literature has been preoccupied with the journey of the anti‐hero rising to power, less has been written about the organization of the party once it has transcended to political influence. Likewise, whereas organizational birthmarks and imprinting have been integral concepts in the study of organizations, there has been little permeation of the concepts into the study of political parties. The Danish People's Party and Norwegian Progress Party provide two illustrative cases, showing that their original formation and later transformation into the current parties brought with it challenges to their structure and ideology. Our findings show that while an increase in external support to the political party, that is, votes, imprints organizational birthmarks, it is during a decrease in the very same external support that organizational birthmarks are uncovered and challenged. Through process‐tracing and our theoretical model, we identify organizational birthmarks and causal mechanisms in which competing organizational birthmarks create an internal division within the political party.
