On 11 May 1812 Spencer Perceval (age 49) was assassinated at House of Commons. Robert Jenkinson 2nd Earl Liverpool (age 41) was appointed Prime Minister.

At 5:15 pm, on the evening of 11 May 1812, Perceval was on his way to attend the inquiry into the Orders in Council. As he entered the lobby of the House of Commons, a man stepped forward, drew a pistol and shot him in the chest. The assassin, John Bellingham, was a merchant who believed he had been unjustly imprisoned in Russia and was entitled to compensation from the government, but all his petitions had been rejected.

Perceval left a widow and twelve children aged between three and twenty. Parliament voted to settle £50,000 on Perceval's children, with additional annuities for his widow and eldest son.

On 18 May 1812 John Bellingham was hanged at Newgate Prison, London [Map]. René Martin Pillet says ...

This unfortunate man had presented several memorials, and had repeatedly demanded audience, but they had given him no answer. Driven to despair, he presented himself at the door of the house of commons, waited for the prime minister, Mr. Percival, and shot him. He was seized, confessed the crime, was tried, condemned to be hung, and executed a few days after. At the time of execution an immense crowd filled the public square, and these expressions were heard on every side: Farewell poor man, you owe satisfaction to the offended laws of your country, but God bless you! you have rendered an important service to your country, you have tdugllt ministers that they should do justice, and grant audience when it is asked of them.

A subscription was opened for the widow and children, and a handsome sum was raised. Their fortune was ten times greater than they could ever have expected in any other situation.
