Final answer:
The representatives from the seven colonies met in Albany, New York, to discuss the Albany Plan of Union during the Albany Congress.
Step-by-step explanation:
The representatives from the seven colonies met in Albany, New York to discuss the Albany Plan of Union. This meeting, known as the Albany Congress, was significant as it was the first instance in a series of colonial wars where the colonies considered a formal union to address defense against the French and improve relations with Indigenous people, particularly the Iroquois. Although the Iroquois did not commit to an alliance with the British, the Albany Congress spent much of its time debating Benjamin Franklin's Plan of Union, which proposed a colonial union with a 'grand council' and a president appointed by the Crown. Ultimately, the plan was not adopted because, despite being approved by the delegates, the individual colonies and the Colonial Office were concerned about losing their autonomy.
