Step-by-step explanation:
The Second Continental Congress was significant because it marked a turning point in the American Revolution. The Congress came together in May 1775, shortly after the battles of Lexington and Concord, to consider the response of King George III to the petition drafted by the First Continental Congress. Congress initially aimed for reconciliation with the mother country, but it soon became clear that independence was the only option. As a result, a committee was formed to draft the Declaration of Independence, which was released to Congress on July 4, 1776.
