Answer:
After the Albany Congress passed the Albany Plan, the plan was sent back to the British and to the individual American colonies. The British government thought the proposed colonial government was unnecessary and, as such, rejected it. The individual American colonies also rejected it.
This plan was an attempt to stop the French from taking control of the Ohio River valley, because if they had, it would link the French territories of Louisiana and Canada together and block the growth of the English Colonies.
The Albany plan of Union failed because the colonies were afraid of losing their own autonomy or self government. The British also dropped the plan because they wanted to make the management of the colonies simple.
The Albany Plan of Union was a plan to place the British North American colonies under a more centralized government. Although never carried out, the Albany Plan was the first important proposal to conceive of the colonies as a collective whole united under one government.
