Buddhist crisis: Amid worsening relations, outspoken South Vietnamese First Lady Madame Ngo Dinh Nhu arrives in the US for a speaking tour, continuing a flurry of attacks on the Kennedy administration.

The Buddhist crisis was a period of political and religious tension in South Vietnam between May and November 1963, characterized by a series of repressive acts by the South Vietnamese government and a campaign of civil resistance, led mainly by Buddhist monks.

Trần Lệ Xuân, more popularly known in English as Madame Nhu, was the de facto First Lady of South Vietnam from 1955 to 1963. She was the wife of Ngô Đình Nhu, who was the brother and chief advisor to President Ngô Đình Diệm. As Diệm was a lifelong bachelor and because she and her family lived in Independence Palace together with him, she was considered to be the first lady.

John F. Kennedy's tenure as the 35th president of the United States began with his inauguration on January 20, 1961, and ended with his assassination on November 22, 1963. Kennedy, a Democrat from Massachusetts, took office following his narrow victory over Republican incumbent vice president Richard Nixon in the 1960 presidential election. He was succeeded by Vice President Lyndon B. Johnson.
