From about 1721, the new Grand Lodge which had been formed in London in 1717, and would soon spread to the rest of England, Wales, and abroad, pursued a policy of self-publicity and expansion that did not always sit well with other Freemasons. They abandoned the old methods of "drawing" lodges with chalk, (erased with a mop) in favour of tape and portable metal letters. In 1735 they refused admission to the Master and Wardens of an Irish lodge who claimed to be a deputation from Lord Kingston, then Grand Master of Ireland and past Grand Master of the English Grand Lodge. The Irish masons were offered admission if they would accept the English constitution, which they refused. In the 1730s the English Grand Lodge had changed their ritual to stay ahead of public exposures. During this period, London absorbed many economic migrants from Ireland. Those who were already masons were often repelled by the changes introduced by the English Grand Lodge, and either formed their own lodges, or joined one of the many unaffiliated lodges in the capital. In 1751, five of these, and a sixth that had just been formed, united to form a rival Grand Lodge, which quickly became an umbrella organisation for the other unaffiliated lodges in England.
