Dinah was the daughter of Leah and Israel (the man whose name was changed from Jacob to Israel). Israel had 12 sons but Dinah was his only daughter. Much of what is known about Dinah can be found in Genesis, chapter 34.
Her story involves a great deal of tragedy and violence. After Israel and his family traveled to the outskirts of the settlement of Shechem, Dinah was defiled by the son of the man who ruled over the area.
After the men of Shechem had been duped into a false sense of security, two of Dinah's brothers, Simeon and Levi, took swords and killed every male. The settlement then was looted of everything, including women and children.
Later, on his deathbed, as explained in Genesis 49:7, Israel curses Simeon and Levi, "for they have killed men in their anger."
