what was going on in the American colonies during the early 1770's. What kinds of things were "trying men's souls"?

American Revolutionary War and the fight for Independence.

Explanation:

The 'American Revolutionary War' which is also popularly known as the 'American War of Independence' was the major event that was going on during the 1770s. Thomas Paine's words 'trying men's souls' were said in this context only. Paine believed that a republican government and independence is a common sense that must be supported by the majority although he knew that the battle was not going to be easy and would take a lot to achieve them. This made him deduce that this struggle is a good thing as the precious thing like freedom is so valuable that it must 'try men's souls.'
