"there shall be neither slavery nor involuntary servitude in the said territory, otherwise than in the punishment of crimes whereof the party shall have been duly convicted: provided, always, that any person escaping into the same, from whom labor or service is lawfully claimed in any one of the original states, such fugitive may be lawfully reclaimed and conveyed to the person claiming his or her labor or service as aforesaid." what was the impact of this article on the six new states created by the northwest ordinance of 1787?

Hey there Caleb!

This would actually have a amazing and great impact. But let's take a look and actually see why this would be the case!

The big impact that this made was on that this person explaining everything was (in a way) trying to say to STOP slavery.

One part that I wanted to considered is the following: 

"There shall be neither slavery nor involuntary servitude in the said territory, otherwise than in the punishment of crimes whereof the party shall have been duly convicted".

This part stated above, this shows you that slavery would be different, but also, it really depends in the case.

So, if you were in the wrong territory, most likely people who would have more authority would have to right to take you as slaves, and this is what this person was trying to get across.
