Final answer:
The Albany Plan of Union, discussed by delegates at the Albany Congress, proposed a union of colonies with a 'grand council' and a president, foreshadowing the structure of future American government.
Step-by-step explanation:
During the Albany Congress, delegates from various colonies gathered to discuss plans for a collective union. Although Congress and the Colonial Office eventually rejected it due to concerns about losing autonomy, the Albany Plan of Union nevertheless laid the groundwork for future American governance models. The concept of a 'grand council' and a president pointed towards a more unified approach to colonial governance, a significant stepping-stone towards the Articles of Confederation and the Constitution.
