How a Birthday Party at Chinon Kickstarted a Civil War (5 March 1173)
Today is my birthday 😁. And as birthdays go, I could have shared mine with worse people, because 5 March 1133 was also the birthday of Henry II of England, born at Le Mans, one of the most formidable rulers medieval Europe ever produced.
Henry II’s Birthday was 5th March
Soldier, lawgiver, empire-builder, father of eight legitimate children (and countless illegitimate ones), and a man whose family would become both his greatest weapon, his biggest headache, and eventually most spectacular downfall.
Which makes today a good day to talk about what happened on his fortieth birthday, in 1173. Because that evening a feast was held at Château de Chinon. The great hall would have been ablaze with candlelight and Henry, thinking he’d managed to control his spoiled, entitled (but courteous and generous) namesake son, allowed the goblets to be repeatedly refilled by his son’s own hand.
The drunkenness that followed led to everything that followed: the Great Rebellion, where Henry’s family were torn apart, and his throne would never feel secure again.
This event, and the Great Rebellion itself, runs through the heart of my novel Lady of Lincoln.
Friday the 13th Superstitions?
Forget black cats and broken mirrors—those superstitions came centuries later. Here's what people in Nicola de la Haye's time actually feared on an unlucky day.
The Evil Eye Was Everywhere
In 12th-century England, an envious glance could literally kill you. People believed that jealous or malicious looks could cause illness, spoil crops, curdle milk, or even bring death. The wealthy were particularly vulnerable—their success made them targets for envious stares. Protective charms, prayers, and amulets were essential accessories, not fashion statements.
Richard the Lionheart at Sixteen: the Making of a Warrior Duke
In 1173, a boy of sixteen took his first step onto the stage of war. His name was Richard, Duke of Aquitaine, though he had yet to earn the epithet Lionheart.
Before he became the crusader-king of legend, before his songs and sieges, Richard was a restless teenager thrust into the most dangerous political storm of the twelfth century: the Great Rebellion against his father, King Henry II.
It was a rebellion born of pride, family betrayal, and the impossible weight of expectation. And it was here — amid defeat, shame, and fire — that the making of a warrior began.
A Son in His Mother’s Shadow
Richard was Eleanor of Aquitaine’s favourite son, and in many ways her reflection: intelligent, impulsive, proud. Born in Oxford but raised in the cultured courts of Poitiers and Bordeaux, he was steeped in his mother’s world of poetry and politics. By his mid-teens he could compose in Occitan, debate theology in Latin, and command a hall full of barons — yet he was still a boy in a man’s game.
In 1172, Henry II had forced Eleanor to surrender the duchy of Aquitaine to her teenage son, intending to bind the region more tightly to the English crown. But Aquitaine was Eleanor’s inheritance, her life’s work, and Richard was fiercely loyal to her. The gift was both a promotion and a trap: the young duke found himself governing a proud and fractious land, surrounded by lords twice his age and loyalty only thinly pledged.
When the rebellion of 1173 began, Richard stood between two worlds — son of a king, heir to a duchy, and caught between the two towering figures who defined his destiny.
Geoffrey of Anjou: The Handsome Count Who Founded the Plantagenet Dynasty (Died 7th September 1151)
On September 7, 1151, Geoffrey of Anjou — known as “le Bel” or “the Handsome” — collapsed with a sudden fever and died at just 38 years old.
He was never king. He never wore a crown.
And yet, Geoffrey Plantagenet shaped the medieval world more than many monarchs.
Without him, there would be no Henry II, no Richard the Lionheart, no King John and Magna Carta, and no centuries-long Plantagenet dynasty. Geoffrey’s story isn’t just a footnote — it’s the spark that set medieval England ablaze.
Why the Plantenet Angevins Ruled Half of Europe
When most people think of medieval kings, we generally think of one monarch, one kingdom, and then the people below him.. But Henry II of England—first of the Angevin kings—was no ordinary ruler. By the 1170s, he commanded more territory than any other monarch in Christendom, stretching from the wild hills of Northumberland to the sunlit vineyards of Aquitaine. He was king in only England—he was the Norman and Aquitainian duke, the count of Anjou, Touraine, and Maine. But is was all his dominion, and it was so vast that chroniclers called it an “empire,” though it was stitched together by marriage, inheritance, and sheer force of will.
So how did a French count’s son come to rule half of Europe?
