While King Henry VII made peace with Scotland with marriage of his daughter Margaret Tudor to King James IV, eventually English-Scottish relations would turn sour again especially with reign of the second Tudor king Henry VIII. Henry VIII angered King James IV and most Scots by claiming (as many English kings did) that he was their overlord. King James IV tried to take advantage by invading England with his brother-in-law absent fighting another battle. However at the Battle of Flodden, Scotland suffered one of its worst defeats in its history. Not only did they lose so many men and suffered deep political consequences, but their popular and capable king was killed in battle as well.
