The power struggle between the empress Maria Theresa and Jesuits escalated in 1765. Until then, the position of university's "Rector Magnificus" was automatically in the hands of the rector of the Jesuit order. Firstly, the Empress took away the Jesuit's monopoly over the position by imposing that the "Rector Magnificus" was to be elected by academia. As a theologian was elected "Rector Magnificus" in 1765, the empress assumed the power and appointed her own favourite, secular professor of law Johann Heinrich Bösenselle, as the head of university in 1766. Meanwhile, the Empress decided to fortify the town heavily, in line with contemporary practice and reflecting the increased military threat from Prussia. The consequence of constraining the city within its upgraded fortifications was that scope for commercial development became very restricted. Olomouc's experience was in stark contrast with that of Brno to the south, which was further away from the Silesian war zones, and which became the centre of the Moravian Industrial Revolution.
