George I died on 11th June 1727 at a time when many future Jockey Club members were bonding together. Many of them subscribed to both 5 year periods of the Noblemen and Gentlemen's Contribution Purses from 1717 to 1721 and again from 1722 to 1726, and a number of them had regular runners in the Kings Plates run on a number of racecourses. Furthermore, most of the widely accepted future Jockey Club members also subscribed to the Wallasey Stakes in Cheshire. When the second phase of the Noblemen and Contributions Purse was completed in October 1726 the burgeoning Jockey Club launched the October Sweepstake, pitched at 20 guineas, for horses not exceeding 5 who had only ever started at Newmarket. The new event lasted for two 5-year periods, initially from 1727 to 1731, the first being won by the appropriately named Sweepstakes, and then the subscription was increased to 25 guineas between 1732 and 1736. For the second October Stakes there were 11 Contributors, namely Duke of Bolton, Duke of Bridgewater, Duke of Devonshire, Duke of Somerset, Earl of Godolphin, Earl of Halifax, Lord Viscount Middleton, Lord Gower, Sir Michael Newton, Edward Coke and Robert Honeywood.
