Final answer:
The 1820 Missouri Compromise is an example that supports Locke's interpretation, as it illustrated a reasoned legislative effort to handle the slavery issue in the spirit of Enlightenment philosophy, aiming at maintaining national unity.
Step-by-step explanation:
To support Locke's interpretation of historical events being shaped by reason and market forces, one could use the example of the 1820 Missouri Compromise as a specific historical event between 1800 to 1860. The Missouri Compromise was a vital development proving that legislative measures and compromises were sought to maintain the balance of power between free and slave states, which was essentially an attempt to rationalize and provide a structured approach to the contentious issue of slavery across expanding American territories.
This event aligns with Locke's Enlightenment philosophy, given that it represented a reasoned attempt to manage political and social conflicts and maintain national unity amidst divisive issues.
