The Great Wall of China is a series of stone and earthen fortifications in northern China, built originally to protect the northern borders of the Chinese Empire against intrusions by various nomadic groups. Several walls have been built since the 5th century BC that are referred to collectively as the Great Wall, which has been rebuilt and maintained from the 5th century BC through the 16th century. One of the most famous is the wall built between 220–206 BC by the first Emperor of China, Qin Shi Huang. Little of that wall remains; the majority of the existing wall was built during the Ming Dynasty.
The Great Wall stretches from Shanhaiguan in the east, to Lop Nur in the west, along an arc that roughly delineates the southern edge of Inner Mongolia. The most comprehensive archaeological survey, using advanced technologies, has concluded that the entire Great Wall, with all of its branches, stretches for 8,851.8 km (5,500.3 mi). This is made up of 6,259.6 km (3,889.5 mi) sections of actual wall, 359.7 km (223.5 mi) of trenches and 2,232.5 km (1,387.2 mi) of natural defensive barriers such as hills and rivers.

The Empress of China was a three-masted, square-rigged sailing ship, initially built in 1783 for service as a privateer. After the Treaty of Paris brought a formal end to the American Revolutionary War, the vessel was refitted for commercial purposes . It became the first American ship to sail from the newly independent United States to China, opening what is known today as the Old China Trade and transporting the first official representative of the American government to Canton.
The first American merchant vessel to enter Chinese waters left New York harbor on Washington's birthday, February 22, 1784. The Empress returned to New York on May 11, 1785 after a round voyage of fourteen months and twenty-four days. The success of the voyage encouraged others to invest in further trading with China.
The ship's captain John Green (1736-1796) was a former U.S. Naval officer, its two business agents (supercargos), Samuel Shaw (1754-1794) and Thomas Randall (17... -1811), were former officers in the U.S. Continental Army, and its syndicate of owners, including Robert Morris (1734-1806) were some of the richest men in the new nation.
