The Great Wall of China

The Great China Wall

The Great Wall of China, one of the greatest wonders of the world,It made of stone, brick, tamped earth, wood, and other materials, generally built along an east-to-west line across the historical northern borders of China in part to protect the Chinese Empire or its prototypical states against intrusions by various nomadic groups or military incursions by various warlike peoples or forces.Other purposes of the Great Wall have included border controls, allowing the imposition of duties on goods transported along the Silk Road, regulation or encouragement of trade and the control of immigration and emigration.
The construction of the Great Wall China began in the 7th century B.C., under the Dynasty Zhou. This wall was constructed along many hundreds of years. The first version of the wall was constructed to support invaders far from the villages that cultivate the land for the Chinese border. These walls were constructed in weak points in the natural landscape or where the threat was perceived like the major one.
Some of these walls eventually became of greater strategic importance when the localised defences were gradually joined to form the Great Wall of China. At those times that the Chinese territory expanded northward, earlier walls became secondary defences when a more northerly wall was built. The Great Wall of China was built by soldiers, civilians, farmers and prisoners, primarily during three dynasties: the Qin, the Han and the

Ming, although the Sui Dynasty and the Ten Kingdoms period also played a part. The building styles of each dynasty added their own flavour and advanced the techniques learned from the previous.
 The first dynasty of China was the short lived Qin Dynasty. The first emperor, Qin ShiHuang, was a tyrannical emperor who unified China by force and set about constructing one Great Wall by joining. He even sent scholars to work on the Great Wall, anyone who was deemed unproductive. These workers faced arduous labor, and the constant danger of being attacked by bandits.
