Not looking for anything having to do with the theological development of the Catholic Church, what I'm interested in is how the Church accumulated and exercised political and economic influence. To some extent that's probably inextricably tied up with the theology, but I'm looking for a book (or podcast or documentary or lecture) that is primarily focused on explaining the political and economic side of things. Basically, looking at the Church as an institution, but looking past the fact of it being a religious institution, and considering it as a political and economic institution (like a nation, empire, or multinational corporation). I thought it would be easy to find something along these lines, but I've failed so far!
