Alexander Hamilton [SEP] On slavery
By the time of Hamilton's early participation in the American Revolution, his abolitionist sensibilities had become evident. Hamilton was active during the Revolution in trying to raise black troops for the army, with the promise of freedom. In the 1780s and 1790s, he generally opposed pro-slavery southern interests, which he saw as hypocritical to the values of the American Revolution. In 1785, he joined his close associate John Jay in founding the New-York Society for Promoting the Manumission of Slaves, and Protecting Such of Them as Have Been, or May be Liberated, the main anti-slavery organization in New York. The society successfully promoted the abolition of the international slave trade in New York City and passed a state law to end slavery in New York through a decades-long process of emancipation, with a final end to slavery in the state on July 4, 1827.
