Lack of resources and the English Channel.
Because I love cheese
The French Army was not prepared for the severity of Russian winters.
With regard to Russia, it is the sheer size of the country that creates the challenge. A Russian Army can retreat until the supply chain of an invading Army can no longer be managed and falls of its own weight. The UK is an Island Nation with a superb Navy and Naval Tradition to its credit. The English Channel is a defensive moat that even today is a serious challenge for any Amphibious Operation.
Portugal, United Kingdom, Russia.
No, he invaded Russia due to Czar Alexander breaking his word about sticking with the Continental System, which was a boycott against trading with the British.
Russia failed to join in the Economic Boycott of the United Kingdom called the Continental System.
Great Britain, Prussia, Russia and Austria.
Russia and Spain were his undoing. Egypt also if you're honest.
Napoleon created the CONTINENTAL SYSTEM, which was an economic blockade (or embargo) by France and all French allies on the European Continent (Prussia, Austria, and Russia -- they were allies because they surrendered to France) on the United Kingdom. The embargo was actually relatively successful in destroying the British economy.However, an embargo harms the economies of both groups who do not trade with each other and Russia was far more dependent on trade with the United Kingdom than the UK was on trade with Russia. As a result, Russia broke the embargo and began trading with the United Kingdom. In order to compel Russia to follow the rules of the blockade, Napoleon was pressed to invade Russia and force a re-capitulation to the previously-agreed-to terms. This invasion, ironically, served to be Napoleon's undoing, leading to the destruction of his victorious armies.
