July 10 – The Albany Plan of Union is given official approval by the delegates from New York, Pennsylvania, Maryland, Rhode Island, New Hampshire and Massachusetts, with Connecticut opposing. The plan approved at the meeting in Albany, New York is based on Benjamin Franklin's suggestions of "a general union of the British colonies on the continent" for a common defense policy. As amended at the assembly, the proposed union calls for the British Parliament to approve the arrangement, which would encompass all of the British North American colonies except for Georgia and Nova Scotia. The plan, to be considered by the individual colonies for ratification, provides for an inter-colonial legislature (the Grand Council) composed of between two and seven representatives for each colony, depending on population. It also provides for a "President General" who can veto Grand Council legislation, a common defense budget with colonies contributing proportionately to their representation, and an inter-colonial army whose officers would be selected by the Grand Council.<ref name=Rogers>Alan Rogers, Empire and Liberty: American Resistance to British Authority, 1755-1763 (University of California Press, 1974) pp13-19</ref>
