Final answer:
The Albany Plan proposed during the Albany Congress sought to form a colonial union with a 'grand council' and president appointed by the Crown, but was rejected over autonomy concerns. It later influenced the Articles of Confederation and the U.S. Constitution.
Step-by-step explanation:
The Albany Plan was a proposal developed during a meeting known as the Albany Congress in 1754, which aimed to create a unified government for the Thirteen Colonies. Benjamin Franklin's Plan of Union suggested the formation of a "grand council" to pass legislation and a president to be appointed by the Crown. Although the Albany Plan was initially approved by the delegates at the Congress, it was later rejected by both the colonial assemblies and the British Colonial Office due to fears of losing autonomy. Nevertheless, the Plan of Union significantly influenced later American governmental structures, including the 1777 Articles of Confederation and the United States Constitution.
