Dinah was Jacob and Lea’s daughter. Her existence was mentioned only one time in written history while the 12 sons of Jacob, the 12 tribes, are well known. The episode of Dinah’s  rape by the prince Shechem and its implications is one of the powerful stories in my opinion through the history of women. 
Today we continue to see this horrible stories of women in history being neglected and ignored, being abuse, raped and even gets killed on behalf of family respect. We must bring these stories to light.
Dinah, the daughter of Leah and Jacob, went out to visit the women of Shehem, where her people had made camp and where her father Jacob had purchased the land where he had pitched his tent. Shechem (the son of Hamor, the prince of the land) "took her and lay with her and humbled her. And his soul was drawn to Dinah ... he loved the maiden and spoke tenderly to her", and Shechem asked his father to obtain Dinah for him, to be his wife.
Shechem offered Jacob and his sons any bride-price they named. But "the sons of Jacob answered Shechem and his father Hamor deceitfully, because he had defiled their sister Dinah"; they said they would accept the offer if the men of the city agreed to be circumcised. 
So the men of Shechem were deceived, and were circumcised; and "on the third day, when they were sore, two of the sons of Jacob and Leah, Simeon and Levi, Dinah's brothers, took their swords and came upon the city unawares, and killed all the males. They slew Hamor and his son Shechem with the sword, and took Dinah out of Shechem's house, and went away." And the sons of Jacob plundered whatever was in the city and in the field, "all their wealth, all their little ones and their wives, all that was in the houses."
In 19th-century America, "Dinah" became a generic name for an enslaved African woman. At the 1850 Woman's Rights Convention in New York, a speech by Sojourner Truth  was reported on in the New York Herald , which used the name "Dinah" to symbolize black womanhood as represented by Truth:
In a convention where sex and color are mingled together in the common rights of humanity, Dinah, and Burleigh, and Lucretia, and Fredrick Douglas are all spiritually of one color and one sex, and all on a perfect footing of reciprocity. Most assuredly, Dinah was well posted up on the rights of woman, and with something of the ardor and the odor of her native Africa, she contended for her right to vote, to hold office, to practice medicine and the law, and to wear the breeches with the best white man that walks upon God's earth.
