was the influential and controversial de facto First Lady of South Vietnam,
known for her forceful personality and striking beauty,
for her advocacy for gender equality, and for
her audacity in challenging powerful men, including US and South Vietnamese

Diệm, she was among the most important yet poorly
understood figures in postcolonial
South Vietnamese politics.
