What event was summoned by the British government to foster greater colonial unity?

The Albany Congress was an important early attempt to foster greater unity among the American colonies, especially in response to shared concerns about territorial expansion and defense against Native American tribes and French encroachment. Convened in 1754, it brought together representatives from several colonies to discuss collective action, particularly around the issue of defense during the French and Indian War.

One of the key outcomes of the Albany Congress was the proposal for a mutual defense pact among the colonies, commonly referred to as Benjamin Franklin's "Join, or Die" plan. Although the plan ultimately did not gain sufficient support for implementation, the Congress itself marked the first significant effort at coordination among the colonies. This early attempt laid the groundwork for future collaborative efforts, especially in the face of British policies in the decade leading up to the American Revolution.

In contrast, the other events listed, while significant in their own right, either did not focus on fostering colonial unity in the same way (like the Boston Tea Party, which was more about protest), or occurred later (like the First Continental Congress, called in 1774, which was more directly in response to British policies) and were built upon earlier discussions such as those at the Albany Congress.
