Whipping

 In Britain whipping women was banned in 1820 but for men, it went on well into the 20th century. From 1862 the courts could order whipping with the cat o'nine tails or birching (which meant hitting a man on the bare backside with a bundle of birch rods). Birching gradually replaced whipping, although cases of the latter were recorded in Britain until 1947. In 1948 whipping or birching civilian men was abolished but it was legal in prisons until 1967.

The Guillotine

On 25 April 1792 Nicolas Jacques Pelletier became the first person in France to be guillotined. But beheading devices were used in other parts of Europe much earlier. A beheading device was recorded in Dublin in 1307. Read more in my history of punishments.
