Final answer:
Napoleon's abdications led to the short-lived Bourbon Restoration. This was, later, followed by the formation of the French Third Republic.
Step-by-step explanation:
After Napoleon's first abdication, the Bourbon monarchy was restored under Louis XVIII, establishing a constitutional monarchy. Napoleon's second abdication, following the Battle of Waterloo, resulted in a brief transition before the monarchy was again restored, leading ultimately to the establishment of the Third Republic.
The first abdication in 1814 brought about the Bourbon Restoration which attempted to re-establish a constitutional monarchy under Louis XVIII. However, after the Hundred Days and Napoleon's final abdication in 1815, the French monarchy faced political turmoil, leading to another restoration of the Bourbons. The regime struggled with ongoing unrest and changes until the national turmoil and war led to the formation of a provisional government that became the origin of the French Third Republic.
