Magazines flourished after Napoleon left in 1815. Most were based in Paris and most emphasized literature, poetry and stories. They served religious, cultural and political communities. In times of political crisis they expressed and helped shape the views of their readership and thereby were major elements in the changing political culture. For example, there were eight Catholic periodicals in 1830 in Paris. None were officially owned or sponsored by the Church and they reflected a range of opinion among educated Catholics about current issues, such as the 1830 July Revolution that overthrew the Bourbon monarchy. Several were strong supporters of the Bourbon kings, but all eight ultimately urged support for the new government, putting their appeals in terms of preserving civil order. They often discussed the relationship between church and state. Generally, they urged priests to focus on spiritual matters and not engage in politics. Historian M. Patricia Dougherty says this process created a distance between the Church and the new monarch and enabled Catholics to develop a new understanding of church-state relationships and the source of political authority.
