New York played a pivotal role in the Revolutionary War. The colony verged on revolt following the Stamp Act of 1765, advancing the New York City–based Sons of Liberty to the forefront of New York politics. The Act exacerbated the depression the province experienced after unsuccessfully invading Canada in 1760.

In that aftermath the New York Provincial Congress on June 9, 1775 for five pounds sterling for each hundredweight of gunpowder delivered to each county's committee.
