The aggregate movement gained momentum as the American Civil Rights Movement continued to grow, and became revolutionary with the expansion of the US government's extensive military intervention in Vietnam. As the 1960s progressed, widespread social tensions also developed concerning other issues, and tended to flow along generational lines regarding human sexuality, women's rights, traditional modes of authority, experimentation with psychoactive drugs, and differing interpretations of the American Dream. Many key movements related to these issues were born, catalyzed, or advanced within the counterculture of the 1960s.  - France, officially the French Republic, is a country with territory in western Europe and several overseas regions and territories.
