This learning resource focuses on the Qing Dynasty and the Canton System, which were crucial for maintaining China's political legitimacy and its perception as the 'Middle Kingdom' during the 18th century. The activity includes a fictional letter from a British merchant requesting expanded trading rights beyond Canton, highlighting the challenges faced by foreign traders and the geopolitical dynamics of the time. Learners are encouraged to adopt the perspective of a Qing official to understand why the empire restricted trade to a single port, supporting the empire's control and stability. Additionally, the resource guides students through the Claim-Support-Question routine to analyze the impact of the Canton System on imperial control and invites them to reflect on the historical concept of the Mandate of Heaven, connecting it to the decisions made by the emperor.
