  The Magnetic Compass for AP World History

  The magnetic compass is an illustrative example in the Technological Innovations topic of Unit 4 of AP World History. Read more about the magnetic compass below!

  The invention of the magnetic compass stands as a landmark moment in the history of navigation, profoundly influencing the success and scope of the Age of Exploration. Emerging in ancient China, the magnetic compass became a transformative tool that empowered sailors to navigate the vast and uncharted expanses of the open seas, opening new horizons for exploration, trade, and cultural exchange.

  The magnetic compass originated in ancient China during the Han Dynasty (2nd century BC to 2nd century AD). Initially used as a divination tool, the compass evolved into a navigational instrument by the Tang Dynasty (7th to 10th centuries AD). The compass consisted of a magnetized needle aligned with the Earth’s magnetic field, enabling it to reliably point north.

  During the Age of Exploration (15th to 17th centuries), European explorers embraced the magnetic compass as an indispensable aid for navigation. Navigators such as Christopher Columbus, Vasco da Gama, and Ferdinand Ma
  
  

  Zheng He and the Compass
  

       In 1405, Zheng He of the Ming Dynasty launched a series of seven naval expeditions that dwarfed all other previous explorations of the same nature.  These seven expeditions, which accommodated over 300 ships and over 25,000 men, led the Chinese explorer through the Strait of Malacca, to India, around the Arabian Peninsula, and ultimately, to Africa's Swahili coast.  Throughout his travels, Zheng He stood as a symbol of Chinese influence, promoting the tribute system, and establishing a level of foreign diplomacy. 
       The main navigational tool Zheng He used in his voyages was the compass, in accordance with astronomical navigational charts.  Zheng He most notably used a "wet compass"; a magnetized needle would float in a circular basin of water, and 24 navigational points would be marked on the outer rim.  This technology allowed Chinese fleets to have a more strict sense of direction when sailing throughout the Indian Ocean
