How can I make history a meaningful career? How can activism fit in with history?

I really enjoy history and would love to have a more scholarly career. However, it bothers me that a job history doesn’t really imply a shaping and changing of the future, while I would like to have a more meaningful effect in working towards positive change. What are your opinions on the relevance of history and how it can be meaningful? Are there are any careers you can think of that would combine history and activism? (I am also not so much interested in studying activism)
