She adopted the numerous children produced by Dessalines' adulterous affairs. She was a contrast to her husband in her tolerance and support and by showing indiscriminate kindness to people of all colors. She was a great opponent of Dessalines' policy toward the white French people of Haiti; she saw to the needs of the
prisoners, and she did not hesitate, despite her husband's anger, to save many of them from battle wounds suffered during the revolution war. She is reported to have fallen to her knees before him to beg him to spare their lives and is said to have hidden one of them, Descourtilz, under her own bed to save him. She was made Empress of Haiti in 1804 upon the creation of the monarchy of Haiti, and crowned with her husband at the Church of
Champ de Mars on 8 October 1804. She kept the status for two years. == Later life ==
