How Did King Henry The Eighth Wives Die?

Cathrine of Aragon, Catherine Parr and Anne of Cleves died normally.
Anne Boleyn and Catherine Howard were beheaded.
Jane Seymour died of a childbirth fever.

Catherine of Aragon died normally,
Anne Boleyn is executed by Henry VIII himself because she cannot give him a son.
Jane Seymour, his 3rd wife, died in child birth ( she finally gave Henry the son he so desperately wanted, Edward VI)

I'm not sure about the others but hope these helped! :p

His first wife he divorced and she died afterwards from some illness, his second was beheaded for treason and incest, Jane was killed during childbirth, His fourth wife he divorces because she was already offered to another noblemen and dies later, his 5th wife is beheaded for treason because of adultery, and his last wife doesnt die until after Henry dies.
