What is the major conflict of Huckleberry Finn?

How can you narrow it down??! Well, the conflict of social inequity is certainly at the forefront of this novel. The theme of justice certainly ties into this, as well. The Widow Douglas tries to instill christian and family values in Huck, yet she owns Jim and is treated as property. Ironically, Jim has the only true family and morally conscious family in the novel. Huck struggles with his own feelings of right and wrong on this issue, at times understanding the injustice of owning human beings, but breaking the law in helping Jim escape.
