“The Right Worshipful Grand Lodge of the Most Ancient and Honorable Fraternity of Free and Accepted Masons of Pennsylvania and Masonic Jurisdiction Thereunto Belonging is the premier masonic organization in the Commonwealth of Pennsylvania. The Grand Lodge of Pennsylvania claims to be the oldest Grand Lodge in the United States, and the third oldest in the world after England (est. 1717) and Ireland (est. 1725), having been originally established as the Provincial Grand Lodge of Pennsylvania in 1731. This claim is disputed by both the Grand Lodge of Massachusetts and the Grand Lodge of Virginia.
The Grand Lodge of Pennsylvania is the largest Grand Lodge, in terms of membership, in the United States. In 2013 it reported a membership of 107,731 and was the only Grand Lodge in the United States to have membership above 100,000. It is only surpassed in membership by the Grand Lodge of England on a worldwide scale.” (Wikipedia)
