Why Is the Sacco and Vanzetti trial important?

Sacco and Vanzetti were convicted because of their political beliefs and ethnic background.

Sacco and Vanzetti were members of the Galleanists, a militant Italian-American anarchist group suspected of a string of bomb attacks in the United States including the September 1920 Wall Street bombing that claimed over 30 lives, and which may have been a reprisal against Sacco and Vanzetti's arrest and indictment. Both men claimed to be victims of social and political prejudice and both claimed to be unjustly convicted of the crime for which they were accused.
