What is the importance of the Ole Deluder Satan Act? Why was it made? I know that required that towns with 50 or more families establish schools, but what is the connection with the school system?

It was the first law requiring towns to establish public schools. It was made to reflect Calvanist views that the illiterate were fair prey for Satan.
That act established the principle that it is society's responsibility (not the parents') to educate children. For more information, check this article.
