Answer:
critically important
Explanation:
In this excerpt, pivotal is referring to the year 1775. The passage is saying that the year 1775 marked a turning point that was critical in the development of the American colonies.
Before 1775, the only manifestation of the massive public discontent with the abusive British tax laws had been unarmed resistance. After 1775, this struggle became an armed one and transformed in the War for Independence that would make the American colonies an independent nation free from the British crown.
