The European political landscape was dominated by the Napoleonic Wars, a series of conflicts declared against Napoleon's First French Empire and changing sets of European allies by opposing coalitions that ran from 1803 to 1815.
Explanation:
The French Revolution broke out in 1789, and its effects reverberated throughout much of Europe for many decades. World War I began in 1914. Its inception resulted from many trends in European society, culture, and diplomacy during the late 19th century. The 19th century saw large amounts of social change; slavery was abolished, and the First and Second Industrial Revolutions (which also overlap with the 18th and 20th centuries, respectively) led to massive urbanization and much higher levels of productivity, profit and prosperity.
