In the 18th century after Slavonia being released of Ottoman Empire and after 150 years of timar-sipahi system, Brod entered a new phase in its historical development. It came under the Habsburg crown and started to develop within newly founded Slavonian military border. Because of the influence of cameralism in the highest military and state ranks, Brod formed itself as a defensive bordering town with a task of becoming an economic developer of Slavonian Posavina. Considering that, the Brod Fortress and military community can be seen as an urbanistic, economic and social developing features. Military community organisation in Brod lasted from 1753 to 1787 and, under cameralistic principles of economic management of Vojna krajina, it encouraged crafting and trade, but obstructed agricultural development. This, along with the development of citizenship, influenced the social stratification of the Brod’s population, which for the first time, although to a limited extend, could have governed its town through administrative body magistracy. After having built new baroque fortress in the 18th century Brod got military characteristic, whose effects on urbanistic development are also noticeable today.
