Neither the Qin wall nor the Ming fortifications were called the “Great Wall of China” by their Chinese contemporaries. That label, and the myths that have come with it, appear to have originated in the West. Europeans who visited China in the 17th and 18th centuries confused the Ming fortifications with the Qin wall or walls mentioned in dynastic histories. They also assumed incorrectly that impressive masonry walls like those surrounding Beijing at the time also extended far to the west. As a result, a description developed in the West of a vast wall that had secured peace for the civilized Chinese for thousands of years by excluding the nomads. This idea captured the imagination of Westerners, and by the late 19th century a visit to the ‘Great Wall of China’ had become a staple of the Western tourist’s itinerary.
In the 20th century the Chinese also began to adopt the idea of the Great Wall, despite the evidence presented by their own historical records. Revolutionary leader Sun Yat-sen, who was instrumental in establishing the Republic of China in 1912, wrote about the wall in glowing terms consistent with the Western myth. Although some Chinese scholars pointed out Sun’s errors, they never succeeded in halting the myth’s progress. Patriotic fervor during World War II (1939-1945) popularized the myth of the Great Wall, and some renovation was done to the Ming fortifications in the early 1950s. The tide changed, however, under Communist leader Mao Zedong, who came to power in 1949. In 1966 Mao launched the political campaign known as the Cultural Revolution, during which he appealed to the Chinese people to destroy anything associated with traditional culture. Unappreciated for its historic value, the magnificent wall surrounding Beijing was torn down for quarrying during this period. Other wall ruins were also destroyed.
With the end of the Cultural Revolution and the death of Mao in 1976, the political climate changed in China, evidenced in part by a rise in nationalism. In the years that followed, the myth of the Great Wall was officially propagated throughout the country. In the 1980s the Ming walls began to undergo extensive renovation at their most visited locations. In the 1990s, however, historians in both China and the West began to reestablish the actual history of Chinese wall building and to explore the development of the folklore surrounding the Ming walls.
