Little did he know, revolving doors would be cleaner and more energy efficient than standard doors - but hardly anyone would use them. Van Kannel's patent, #387571, was based off of an existing door invented by German H. Bockhacker: Tür ohne Luftzug, or "door without draft of air." It was initially called a "storm door structure," and true to its original name, its aim was to keep the outside elements outside.The design was about eight times more efficient than regular doors, in fact. But for a variety of reasons - design, difficulty of use - most people have preferred to use regular doo..

Driven by a desire to spread the French revolutionary principles throughout Europe, Napoleon first conquered Egypt to cripple British trade. He returned to France and, using both diplomacy and warfare, conquered neighboring states. Because much of Europe at the time was fragmented principalities and semi-autonomous states similar to modern Monaco or Luxembourg, it was simple to take over each country a bit at a time.\nAlthough the French Empire ultimately failed, Napoleon changed the face of Europe, forcing the consolidation of Italy and Germany and crippling the power of the aristocracy.

There is no fixed date documenting when the Makah Tribe began its tradition of whaling. As of 1998, some scientists put the tradition back at least 2,000 years, although some Makah Elders put the tradition back even further. This tradition defined the Makah way of life from that point on.\nThe Makah Tribe eventually made indirect contact with European explorers, including the diseases the newcomers brought. Smallpox, tuberculosis, influenza and whooping cough decimated many members of the tribe, and as the tribe could not explain it, the epidemics affected the passing of oral tradition. Smallp..

Although the Panic of 1837 took place before most modern technology existed and while slavery was still a big part of the American economy, it is an example of a financial crisis triggered by a real estate bubble similar to the financial crisis of 2007. The availability of easy credit led to a dramatic upswing in prices for things like land, cotton and slaves. Jackson's policies also allowed multiple banks to issue private banknotes, which further complicated the financial situation that eventually led to a dramatic crash.

Hunting was a small part of the food Mayans consumed. In fact, their farming practices are the major source of food and they also procured fresh honey from keeping bees. They used slash and burn agriculture, which means that they cut down forested areas for farming and then they burned the trees to get rid of them. Their staple food was maize, but they also had sweet potatoes, watermelons, beans, squashes, papaya, chilies and avocados on their farms.

There are several theories as to why Mayan civilization collapsed. There is evidence that overpopulation occurred, so the environment was no longer able to sustain them. There is also evidence of a 200-year drought, which would have affected many Mayan cities in the southern lowlands by reducing the water available. Several other series exist as to why the Mayan civilization collapsed, such as peasant revolts, foreign invasion, epidemic disease and climate change.

The Mauryan Empire ruled the Indian subcontinent from 322 to 185 B.C. Much of its early history was taken up by conquest. The empire had a huge standing army of cavalry, infantry and war elephants. In addition, an extensive espionage network secured intelligence both domestically and internationally. The central bureaucracy imposed taxation fairly upon all the empire's citizens, and the peace the army imposed enabled a vast expansion of trade. The Mauryan Empire traded with nations as distant as the Greek states of western Asia and to the east all the way to Southeast Asia.\nAt the pinnac..

The General Strike of 1945 marked a turning point in trade unionism in Nigeria, emboldening workers in various trade industries to demand higher wages and better working conditions. Several other noteworthy industrial strikes have been held, including in 1950 by mercantile workers, 1959 by the Airways Workers Union, 1964 by the United Labour Union and by the Nigerian Labour Congress in 2007 and 2011. The cause of many of these strikes was the failure of the government to implement wage improvements and working conditions that had been pledged.
