The second continental congress was a convention that included delegates, or leaders, from the 13 colonies to meet up and discuss the topic of a continental army. The second continental congress decided to make a continental army that involved George Washington in being commander-in-chief. They also adopted the "declaration of causes of necessity of taking up arms" which means that they will have a war, and they had the Revolutionary war.
