The Conspiracy of Lambert Simnel and the Earl of Lincoln (1487)

Background: The Princes in the Tower

• During the 1480s, the fate of Edward IV’s sons (‘Princes in the Tower’) was widely debated.

• Most believed they were killed on the orders of Richard III, but rumours persisted that:

  • One or both had escaped.

  • An impostor had replaced Richard of York.

• This uncertainty encouraged pretenders.

The Earl of Warwick and Rumours (1486)

• The 12-year-old Edward, Earl of Warwick was a Yorkist claimant.

• Henry VII imprisoned him in the Tower to prevent rebellion.

• Rumours circulated that:

  • Warwick had escaped.

  • He had been secretly sent to Ireland and replaced with another child.

• These stories created ideal conditions for a pretender movement.

Emergence of Lambert Simnel (1487)

• In February 1487, Lambert Simnel appeared in Ireland

• He likely claimed to be Warwick (though some say Richard of York)

• He was probably of humble origins

• Encouraged by a priest, Richard Simonds

Supported by Irish Yorkists reflecting Irish dissatisfaction with Tudor rule

Henry’s Response

• Henry paraded the real Warwick through London to prove he was alive and imprisoned.

• This backfired, as:

  • John de la Pole, Earl of Lincoln declared Simnel the real Warwick.

• Lincoln fled to Margaret of Burgundy, who:

  • Provided financial support.

  • Supplied German mercenaries.

Crowning in Ireland

• Simnel was crowned “Edward VI” in Dublin.

• A parliament met in his name.

• Coins were minted bearing his image.

• This transformed the rebellion from farce to serious political threat.

Invasion of England (June 1487)

• 4 June: Yorkist forces invaded England.

• Forces included:

  • 1,500–2,000 German mercenaries.

  • Around 4,000 Irish troops.

• Limited English support (e.g., some Yorkshire magnates).

• Even York city remained loyal to Henry.

The Battle of Stoke (16 June 1487)

• Decisive confrontation at the Battle of Stoke Field.

• Henry’s advantages:

  • Strong defensive position.

  • Effective archers.

  • Poorly equipped Irish troops.

• Results:

  • Lincoln killed.

  • Lovell fled to Scotland.

  • Simnel captured.

Aftermath

• Simnel was pardoned (likely due to his age).

• Employed in the royal kitchens.

• Later reportedly promoted to falconer.

• Played no further political role.

Why It Was Significant

• First serious dynastic threat to Henry VII.

• Involved:

  • Foreign support (Burgundy).

  • Irish backing.

  • A genuine Yorkist noble (Lincoln).

• However, its defeat:

  • Strengthened Henry’s authority.

  • Demonstrated limited appetite for renewed civil war.
