What do we do, make a new SmsLogger class and then replace everywhere in the code instead of the DatabaseLogger() constructor, we initialize new SmsLogger()? That is just waste of time. And the day after tomorrow I no longer want SMS'es but instead something else..
Quick Answer. Napoleon's influence on Europe included the spread of nationalism, shifts in world power, major redrawing of political boundaries and the diffusion of Napoleonic ideas of governance. The political climate of Europe following Napoleon's downfall was very different than it had been prior to his rise to power.
Napoleon more and more saw himself as the Emperor of Europe, and not merely of France. He introduced many French laws and the metric system to the conquered areas of Europe, abolished serfdom and feudal dues. Yet at the same time, he put the interests of France first, and imposed heavy taxes and levies of men and equipment.
