How did Napoleon die? When did he die?

After his collapse in Europe, Napoleon was sent into exile on the island of St. Helena. There he spent the last years of his life. In 1816, his health began to deteriorate constantly, and he was also pursued by constant depression. Doctors at that time said that he was sick with hepatitis, but there were suspicions of more serious illness. In 1821 he was in critical condition. Napoleon died soon after. Thus, he died on Helena Island or Longwood Island.
