The present-day Pine Tree Council (#218) can trace its beginnings to 1919, when organizers formed Portland Council (#218) in that city. South Portland Council was formed a year earlier but that council folded in 1921. In 1922 Portland Council became Cumberland County Council (#218), no doubt reflecting its growth outside of the city of Portland. Between 1922 and 1932 Cumberland County Council continued to grow, adding units in Oxford, Sagadahoc, Androscoggin, Franklin, Kennebec, Knox Lincoln,and Somerset counties. The original Pine Tree Council (#710), formed in Rockland in 1925, merged into Cumberland County Council in 1929, and in 1933 Cumberland County Council became the Pine Tree Council we know today. York County Council (#217) merged into Pine Tree Council in 1935.
