I want to know the answer to the following question:
In what year did an important trial take place which situated New Haven among the forefront of the growing anti-slavery movement?
All the background I'm provided with is that "New Haven was home to one of the important early events in the burgeoning anti-slavery movement when, in 1839, the trial of mutineering Mende tribesmen being transported as slaves on the Spanish slaveship Amistad was held in New Haven's United States District Court.". Is that enough to answer the question?
