Take the following as truth: In 1239, there was the procession of Louis IX, barefoot, carrying his holy treasure, Jesus's Crown of Thorns (now in the Sainte-Chapelle); in 1430, it saw the humiliation of Henry VI of England (he was crowned King of France here; see page 15).
Then the following statement: "Henry IV was the king of France in 1290." is true, false, or inconclusive?
Answer: False
