Explanation:

The two events are simply concurrent. "And" is a proper conjunction to combine the sentences without changing the meaning or introducing incorrect relationships. "But" implies contrast, "when" and "once" imply a time - dependent or conditional relationship which is not accurate here.

Answer:

Thomas Paine's Common Sense was published in 1776, and the Revolutionary War began that same year.
