In accordance with state law, George Washington stipulated in his will that elderly enslaved people or those who were too sick to work were to be supported by his estate in perpetuity. The remaining non-dower enslaved at Mount Vernon did not have to wait for Martha Washington’s death to receive their freedom. Writing on the subject to her sister, Abigail Adams explained that Martha Washington’s motives were largely driven by self-interest. “In the state in which they were left by the General, to be free at her death,” Adams explained, “she did not feel as tho her Life was safe in their Hands, many of whom would be told that it was [in] their interest to get rid of her–She therefore was advised to set them all free at the close of the year.” In December 1800, Martha Washington signed a deed of manumission for her deceased husband's slaves, a transaction that is recorded in the Fairfax County, Virginia, Court Records. They would finally be emancipated on January 1, 1801.
