Welcome to Prime Factors where we review each UK Prime Minister from Robert Walpole to Keir Starmer. We discuss their biography, highs and lows, and then rate them on a scale designed by a 10-year old before awarding the ultimate prize: Are they ”Known” or an ”Ice Cream Cone”? Some dads build a treehouse with their kid. We’re doing a history podcast.

"My Lord, I am sure I can save this country, and no one else can." Britain was losing the Seven Years War and the Duke of Newcastle seemed powerless to stop it. William Pitt had been drummed out of government once, but the mobs in the street still cried out his name. No one had more faith in his abilities than Pitt himself, but could the Great Commoner turn the tide and deliver the British Empire to its greatest victories?

Italian Unification - Part 2 (Feat. Marco Cappelli of Storia d'Italia)
Sunday Oct 26, 2025
Sunday Oct 26, 2025
At Cavour's death, the dream of a united Italy was still incomplete: Rome and Venice remained outside the newly formed Italian Kingdom. Garibaldi cried out for Rome, but it would take the rise of one empire and the fall of another before the ancient Aurelian walls fell and Italy was whole once again.
Featuring Marco Cappelli from Storia d'Italia as our special guest co-host!

Italy was a divided nation, a pawn in the machinations of empires. Camillo Benso, the Count of Cavour, dreamed of a day when Italy could take its place among the nations of the world. As a journalist, Cavour fought for a constitution and parliament. As a statesman, he needed all his cunning (and a little luck) to make friends, scheme with emperors, and pull the disparate parts of Italy together... by force, if necessary.
Recorded on location (and vacation!) in Aosta and Venice, in Italy. Our cover art is the Cavour lego mural in his ancestral home of Santena, Italy, which we visited.

From the depths of the Kollur Mine to the apex of the French crown, the Pitt Diamond (later known as the Regent Diamond) is either the story of a great British adventure, or a terrible Indian tragedy. We retell this story briefly in a bonus scene from William Pitt, Part 1.

As a boy, William Pitt grew up on stories of his merchant adventuring family. The Pitt fortune was smuggled out of the mines of India, even while his grandfather was the Governor of Madras. Pitt's father nearly lost it all betting on the Jacobites, but they survived. As the second son however, William had to find his own way as he sought fortune in the military and government. The story of one of Britain's greatest military leaders begins here.

As the Grenville government was on its final legs, Prince William Augustus, the Duke of Cumberland, was tasked with forming a new one... unfortunately right during the Ascot Races. Fortunately for Charles Watson-Wentworth, he was also enjoying the races that day. No one was more surprised than he was to discover that he was now Prime Minister.
Recorded in Portsmouth, Rockingham County, New Hampshire.

8.1 - Charles Watson-Wentworth, 2nd Marquess of Rockingham (Part 1)

Charles Watson-Wentworth was not a serious person. After failing to run away at 15 to join Cumberland's army, he spent the remainder of his young adulthood entertaining his way across Europe before throwing one of the largest birthday parties that Yorkshire had ever seen. He loved horse racing, not elections. But with the Whigs floundering and Bute in ascendance, could this party boy be just what the nation needed?
