The Politics of Mainz

So here is the setup in Mainz. It is an archbishopric, similar to what Salzburg was in Austria, but much more important. An Archbishop set his sights on Mainz and went to war to drive the incumbent out. It was this latter Archbishop of Mainz that awarded Gutenberg his pension. Therefore, we must assume that Gutenberg provided his service to this Archbishop, possibly before the war. However, the printing of The Bible was done seven years before the second archbishop invaded.
