Definition of "bondservant"

The captain was an upstart, a product of the democratic idea operating upon the poor white man, the descendant of the indentured bondservant and the socially unfit.

1901, Charles W. Chesnutt, The Marrow of Tradition‎

Would the lass but consent to go abroad in the unhallowed place at this awful season and hour of the night, she was as firmly handfasted to the Devil as if she had signed a bond with her own blood; for then, it seemed, the forces of good fled far away, the world for one hour was given over to its ancient prince, and the man or woman who willingly sought the spot was his bondservant forever.

1902, John Buchan, The Outgoing of the Tide
