Communication and division on the northern border of Catalonia between the 15th and 18th centuries

Catalonia's northern border underwent major shifts during the Modern Age. Wars played a significant role in these changes, as evidenced
by the Treaty of the Pyrenees in 1659, a stage in the process which led to the creation of an actual state borderline that the
people gradually started to internalise. Nonetheless, the border dwellers still interacted with each other, making it a place of intense
exchanges which included them within a larger cultural and economic framework in which they strove to live as good neighbours, as
they themselves put it.
