Step-by-step explanation:
The history of the Great Wall of China began when fortifications built by various states during the Spring and Autumn and Warring States periods were connected by the first emperor of China, Qin Shi Huang, to protect his newly founded Qin dynasty against incursions by nomads from Inner Asia
The Great Wall of China visible today largely dates from the Ming dynasty, as they rebuilt much of the wall in stone and brick, often extending its line through challenging terrain.Some sections remain in relatively good condition or have been renovated, while others have been damaged or destroyed for ideological reasons, deconstructed for their building materials,or lost due to the ravages of time.For long an object of fascination for foreigners, the wall is now a revered national symbol and a popular tourist destination.
