On another face are quotations from two of the men commemorated on the monument:
I have devoted myself to the cause of The People. It is a good cause—it shall ultimately prevail—it shall finally triumph.
— Speech of Thomas Muir in the Court of Justiciary on the 30th of August 1793.
I know that what has been done these two days will be Re-Judged.
— Speech of William Skirving in the Court of Justiciary on the 7th of January 1794.

In 1837 the Radical politicianJoseph Hume MP initiated a plan to erect a monument to the five men. Hume chaired a London-based committee to raise public subscriptions in support of the monument and settled on its location being in Edinburgh. In that year the publisherWilliam Tait of Edinburgh wrote on their behalf to theLord Provost of Edinburgh requesting that land be made available on Calton Hill for this end.[2]
The foundation stone was laid by Hume on 21 August 1844, with 3,000 people gathered for the occasion.[3] The Old Calton Burial Ground, and other parts of Calton Hill, are home to a number of other monuments and memorials. The monument was designed byThomas Hamilton, who is also responsible for a number of other structures on Calton Hill, including the formerRoyal High School building and thememorial to Robert Burns.

In February 1852 Hume initiated the erection of a second monument atNunhead Cemetery inLondon. This monument is an obelisk of similar design to its Edinburgh counterpart, but considerably smaller, standing at 33 ft (10 m) high.[4]
The five men commemorated—two from Scotland and three from England—were imprisoned for campaigning forparliamentary reform under the influence of the ideals of theFrench Revolution. Specifically, their support of Palmer's 1793 address that advocated for universal suffrage and annual parliaments was considered incendiary.[5] The five were accused ofsedition in a series of trials in 1793 and 1794, and sentenced to terms ofpenal transportation in the Britishcolony of New South Wales.[6] All but Gerrald travelled together on theconvict transportSurprize; Gerrald left later on the transportSovereign.
Only Palmer and Margarot served their full 14-year sentences and were released. Palmer remained in New South Wales and established a thriving beer-brewing operation near Sydney Cove; he died of a fever on a trading voyage back to England.[6] Margarot departed the colony when his sentence expired, and was the only one of the five to return to the British Isles.
Muir escaped in early 1796, stowing away aboard an American ship and ultimately making his way to revolutionary France where he died on 26 January 1799. On 16 March 1796 Gerrald died inPort Jackson, from tuberculosis exacerbated by a weakness brought on by excessive drinking. Skirving died three days later from either dysentery or an overdose of laudanum.[6]
