Why was the Albany Plan of Union not proved by the colonies?

The Albany Plan of Union, proposed in 1754 by Benjamin Franklin, was not approved by the colonies primarily due to concerns about losing individual autonomy and power. The colonial assemblies were reluctant to relinquish control over their affairs to a centralized government, fearing it would undermine their authority. Additionally, there were differing priorities and interests among the colonies, making consensus difficult. The plan ultimately highlighted the challenge of colonial unity, which would not be fully realized until the American Revolution.
