Note that the Illyrian Provinces were also part of France, but were not organised into departments, and so are not included in this list. Similarly, four additional French departments were also created in Catalonia (annexed from Spain in 1812); their juridical status remained incomplete until the French lost their grip on Spain in 1814. Those departments were: Bouches-de-l'Èbre, Montserrat, Sègre, and Ter.
The names of departments formed from territories annexed to France after 1791 have been colour-coded as follows:
|Former territory of the Kingdom of Sardinia, annexed in 1792 (Duchy of Savoy) and 1793 (County of Nice)|
|Former territory of the Austrian Netherlands and other territories (Liège, Stavelot-Malmedy and Thorn), annexed in 1795|
|Former territory of the Holy Roman Empire on the left bank of the Rhine, annexed on various dates between 1795 and 1801|
|Former territory of the Cisrhenian Republic, annexed in 1802|
|Former territory of the Subalpine Republic (annexed in 1802) and the Ligurian Republic (annexed in 1805)|
|Former territory of the Kingdom of Etruria (annexed in 1807) and the Duchy of Parma (annexed in 1808)|
|Former territory of the Papal States, annexed in 1809|
|Former territory of various German states, annexed in 1810|
|Former territory of the Kingdom of Holland, annexed in 1810|
|Former territory of the Rhodanic Republic, annexed in 1810|
Moreover, the Tanaro department was established in 1802 and disbanded in 1805; it was one of the six original départments which took the place of the Subalpine Republic. Its territory was divided between the three départments of Marengo, Stura, and Montenotte (the latter was created after the annexation of the Ligurian Republic).
