The empire around 400 CE. The broad colours represent prefectural groupings, while regional names, major cities, and symbols for selected state industries show the larger administrative and logistical setting. These groupings contained many individual provinces; a region labelled on this map is not necessarily one province.

The province connected the Adriatic with the routes towards the Alps and Danube. Aquileia’s commerce, public institutions, Christian importance, and strategic position gave it prominence beyond a local agricultural hinterland. Other coastal and inland towns participated in shipping, farming, manufacture, and transit.

Invasions and sieges exposed the northeastern approach to Italy, while political recovery and continuing settlement followed in different places. The movement of populations towards more defensible coastal settings formed part of a long regional transformation. Roman, Gothic, Eastern Roman, and Lombard power successively or simultaneously affected parts of this former province.
