The Gothic art in the 14th century was supported by the culture of city councils, preaching orders (like the Franciscans), and knightly culture. It was the golden age of free Dalmatian cities that traded with Croatian feudal nobility in the continent. Urban organization and the evolution of Dalmatian cities can be followed through the development and expansion of Rab and Trogir, the regulation of streets in Dubrovnik, and the integration of Split. It was also a time of paving the streets with stone, sewage canals, and communalities.
