Mary Bateman Clark (1795–1840) was an American woman, born into slavery, who was taken to Indiana Territory. She was forced to become an indentured servant, even though the Northwest Ordinance prohibited slavery. She was sold in 1816, the same year that the Constitution of Indiana prohibited slavery and indentured servitude. In 1821, attorney Amory Kinney represented her as she fought for her freedom in the courts. After losing the case in the Circuit Court, she appealed to the Indiana Supreme Court in the case of Mary Clark v. G.W. Johnston. She won her freedom with the precedent-setting decision against indentured servitude in Indiana. The documentary, Mary Bateman Clark: A Woman of Colour and Courage, tells the story of her life and fight for freedom.

Polly Strong was an enslaved woman in the Northwest Territory, in present-day Indiana. She was born after the Northwest Ordinance prohibited slavery. Slavery was prohibited by the Constitution of Indiana in 1816. Two years later, Strong's mother Jenny and attorney Moses Tabbs asked for a writ of habeas corpus for Polly and her brother James in 1818. Judge Thomas H. Blake produced indentures, Polly for 12 more years and James for four more years of servitude. The case was dismissed in 1819.
