What major factors played a role in the napoleonic empire decline?

Answer 1

Wagram & Aspern-Essling mark the ending, at least the beginning of the ending, of Napoleons Military supremacy. As wih the forces of many Empires he relies on Allies to supply men with which to fight his battles, notably in this case Bavarians, Saxons, Wurttembergers, Poles & so on. Once he stops winning these friends no longer wish to support him & fade away or change sides. And then there was, of course, the Spanish Ulcer.......... Napoleons Military 'Blitzkreig' was in Italy, against the Austrians & Prussians in 1805 & 06, simply overwhelming, but the Redcoats in Spain were unimpressed, by and large, by the crude column attack & sent it reeling at Busaco & elsewhere. Yes, I know l'Emporeur wasn't there, & had he been at, say, Fuentes d'Onoro things would have been different, but by 1809 Napoleons days of conquest are, for the most part, behind him. But then, as Commanders go he still ranks with the best history has to offer. Vive l'Emporeur !!

Answer 2

Well It collapsed for three main reasons which were his costly mistakes. The first costly mistaje was trying to take over Portugal through Spain. And after napoleon removed their king and replaced him by his brother, the spanish were outraged and started to rebell. The second costly mistake was to try to blockad Britain, so that no one trades with it though this actually helpe Britain because smugglars were able to sell the merchandise for a higher value. The third costly mistake was to try to invade Russia. By this alone, many of troops dies. They reach about 300,000 deaths. Those were the main reasons that led to the downfall of Napoleon's Grand Empire.

Answer 3

The long term reason was that the empire had become too large for being controlled by only a man. As matter of fact, napoleon had the tendency of centralizing the power mainly in his hands.

However the factors which determined the collapse were:

The Continental Blockade, that set up a great grudge against him because it harmed the economy;

the disastrous Russian Campaign and its aftermath.

Answer 4

Guerilla Warfare in Spain, the defeat by the Russian Winter and his Military Defeat at Waterloo. His final defeat was to stomach cancer at St. Helena Island on 5 May 1821.

Answer 5

The Spanish insurgent campaign, the Russian Winter, Trafalgar and Waterloo.
