The Penny Black & the Post
Rowland Hill

📌 Pin it
On May 1, 1840, Britain issued the Penny Black, the world's first adhesive postage stamp, valid for post from May 6. Rowland Hill's reform replaced a maze of distance-based charges — usually paid by the recipient — with a simple idea: one penny, paid in advance by the sender, carried a letter anywhere in the country.
The effect was a correspondence explosion. Letters that had been a luxury became a habit: love letters, business orders, family news, and picture postcards all poured through the expanding network of pillar boxes and mail trains. Literacy and cheap postage fed each other.
Every stamp since descends from the Penny Black, which carried the young Queen Victoria's profile. Britain's stamps still bear no country name — a privilege of having invented the thing.
