proposal. This suggests that either Chalmers had previously read Hill's booklet and was merely elaborating Hill's idea, or he had independently developed the idea of the modern postage stamp. James Chalmers organized petitions "for a low and uniform rate of postage". The first such petition was presented in the House of Commons on 4 December 1837 (from Montrose). Further petitions which he organized were presented on 1 May 1838 (from Dunbar and Cupar), 14 May 1838 (from the county of Forfar), and 12 June 1839. At this same time, other groups organized petitions and presented them to Parliament. All petitions for consumer-oriented, low-cost, volume-based postal rates followed publication of Hill's proposals.

Before then, ink and hand-stamps (hence the word 'stamp'), usually made from wood or cork, were often used to frank the mail and confirm the payment of postage. The first adhesive postage stamp, commonly referred to as the Penny Black, was issued in the United Kingdom in 1840. The invention of the stamp was part of an attempt to improve the postal system in the United Kingdom of Great Britain and Ireland, which, in the early 19th century, was in disarray and rife with corruption. There are varying accounts of the inventor or inventors of the stamp. Before the introduction of postage stamps, mail in the United Kingdom was paid for by the recipient, a system that was associated with an irresolvable problem: the costs of delivering mail were not recoverable by the postal service when recipients were unable or unwilling to pay for delivered items, and senders had no incentive to restrict the number, size, or weight of items sent, whether or not they would ultimately be paid for. The postage stamp resolved this issue in a simple and elegant manner, with the additional benefit of room for an element of beauty to be introduced. Concurrently with the first stamps, the United Kingdom offered wrappers for mail. Later related inventions include postal stationery such as prepaid-postage envelopes, post cards, lettercards, aerogrammes, postage meters and, more recently,
