The article assesses the notion of constitutionalism in late 18th century Hungary and Poland. More precisely, it explores, in a comparative perspective, the constitutional projects of the early 1790s in both countries in the context of their constitutional tradition and as a reflection of the ideas of the Enlightenment.
The assessment of the problem includes brief characteristics of the political structure as well as the crown-estates relationship in Hungary and Poland. Last but not least, in this article I argue that at the bottom of these constitutional projects stood the idea of social solidarity and the concept of the political nationhood in both countries.
