Illyrian Provinces

The Illyrian Provinces were an autonomous province of France during the First French Empire that existed under Napoleonic Rule from 1809 to 1814. The province encompassed large parts of modern-day Croatia and Slovenia, stretching over smaller areas of Italy, Montenegro, and Austria. It maintained an administrative capital in Ljubljana and a military capital in Senj. It encompassed six departments, making it a relatively large portion of territorial France at the time. Adriatic Croatia was split up into two large regions: Civil Croatia and Military Croatia. The former served as a residential enclave and the latter as a military base to check the Ottoman Empire.

In 1809, Napoleon Bonaparte invaded the region with his Grande Armée after key wins during the War of the Fifth Coalition forced the Austrian Empire to cede parts of its territory. Integrating the land into France was Bonaparte's way of controlling Austria's access to the Mediterranean and Adriatic Sea and expanding his empire east. Bonaparte installed four governors to oversee French bureaucracy, culture, and language, the most influential of which was Auguste de Marmont. Marmont was succeeded by Henri Gatien Bertrand (1811–12), Jean-Andoche Junot (1812–13), and Joseph Fouché (1813–14).
