Why did king Louis die?

they were NOT wrongfully executed. When France declared war on Austria, evidence was found that the royal family was leaking out information to Marie Antoinette's brothers (the royal family of Austria). The royal family had thought if France would be defeated, the Austrian forces will impose Louis as an absolute monarch (like he was before) and he will no longer will have share power with the legislative Assembly. whoever wrote they were wrongfully executed certainly does not know so much history...
