Starting with the Invasion of Sicily in July of 1943, and culminating in the June 6, 1944, D-Day invasion of Normandy, Allied forces took the fight to the Axis powers in many locations across Western Europe. The push into Italy began in Sicily, but soon made it to the Italian mainland, with landings in the south. The Italian government (having recently ousted Prime Minister Benito Mussolini) quickly signed an armistice with the Allies -- but German forces dug in and set up massive defensive lines across Italy, prepared to halt any armed push to the north. After several major offensives, the Allies broke through and captured Rome on June 4, 1944. Two days later on D-Day, the largest amphibious invasion in history took place. Nearly 200,000 Allied troops boarded 7,000 ships and more than 3,000 aircraft and headed toward Normandy. Some 156,000 troops landed on the French beaches , 24,000 by air and the rest by sea, where they met stiff resistance from well-defended German positions across 50 miles of French coastline. After several days of intense warfare, Allied troops gained tenuous holds on several beaches, and they were able to dig in with reinforcements and bombardment. By the end of June, Allies were in firm control of Normandy, and on August 25, Paris was liberated by the French Resistance with help from the French Forces of the Interior and the U.S. 4th Infantry Division. In September, the Allies launched another major invasion, Operation Market Garden, the largest airborne operation of its time, in which tens of thousands of troops descended on the Netherlands by parachute and glider. Though the landings were successful, troops on the ground were unable to take and hold their targets, including bridges across the Rhine River. Despite that setback, by late 1944, the Allies had successfully established a Western Front and were preparing to advance on Germany.

The nineteenth European imperialism was motivated by various reasons. The most important of them had to do with the development and growth of a new stage of capitalist economy.
During the 19th century several European countries were changing due to industrial acceleration, which historians call the Second Industrial Revolution. It happened mostly in industry, transportations and communications.
For example, the invention of the dynamo in 1870 soon lead to electric ilumination of cities; the invention of the internal combustion engine allowed for the use of oil and its derivatives as power sources.
This lead to a revolution in transports, virtually reducing distances and accelerating time -- now people would travel and exchange communication much faster than before. The world got smaller and more connected which gave an impression of much more things happening than before.
All of these discoveries and new power sources lead to a greater need of raw material and of consumer markets in order to have groups whom to sell the goods being massively produced. These new necessities would be violently attended through invasion and colonization of several parts of the globe, giving birth to modern imperialism.

One of the major reasons why Native American societies in North America were so diverse was because the tribes were so far away from each other and had very little contact.
