5th January – Death of Philippa of England – Born in the historic county of Northamptonshire, she became Queen, and even Regent, of Denmark, Sweden and Norway.
26th February – Radar first demonstrated – In Upper Stowe.
31st May – Death of Waltheof – 1st Earl of the county and last of the Anglo-Saxon earls.
28th July – Battle of Talavera – Battle honour and anniversary of the Northamptonshire Regiment, who became nicknamed “The Heroes of Talavera”
