No, but powerful slaveholding interests were a major factor in the design of our government. It's the reasons our voting system favors low-population states--because slaves only counted as 3/5 of a person and the slaveholders were worried this would mean less representation in government and the danger that owning slaves would be outlawed.
Slaveholder states would have been perfectly happy for representation to be 1:1 for slaves vs. non-slaves.
