Despite its proven societal value, humanities knowledge tends to be marginalized in research policy; this has been a topic of debate for some time. In this chapter, we focus on the valorization of humanities knowledge, with the aim of comprehending the way this process engenders societal impact. We argue that historical impact stories offer an effective methodological approach for a deeper understanding of such valorization and its subsequent impact. Drawing on three humanities research cases from Sweden, we propose that valorization and impacts of humanities knowledge should be seen as processual and as influenced by societal actors who determine the premises and condition the somewhat unpredictable nature of such impacts. We introduce two concepts: (i) acting space, which involves access to collaborators, audiences, and channels that enable knowledge valorization, and (ii) meandering knowledge flows, which provides insight into the uneven and hard-to-predict nature of valorization. Through these concepts, we wish to provide a better and more nuanced understanding of how knowledge valorization in the humanities unfolds. By doing so, we hope to support humanities scholars to find ways of articulating their own modes of mattering.
