In living history museums, where young people work and volunteer as historically dressed interpreters, participate in field trips, and attend summer camps, young people can simultaneously represent the past, the present and the future. In these spaces, they also shape the past through their questions, their retellings, and their reimaginings based on what matters to them in the present. The paper examines interviews with teen, young adult, and adult heritage interpreters in light of active solidarity and explores how teens and young adults are working to diversify historical narratives, create community, and find joy in these spaces.
