Violations of trade treaty obligations by Austria were considered by Napoleon to be insufficient grounds for a war.[9] There was discussion of whether the presence of an Austrian military garrison in Bologna might justify war against Austria, but the French Emperor was in the end reluctant to use this as a pretext. There were Austrian troops not only in Bologna, but also in Rome and the Papal States, preserving the status quo; in Rome there were also French troops for broadly similar reasons, and parallels between the garrisoning of Bologna and of Rome were uncomfortably close.[2][9]
