Slavery in the United States was officially abolished in 1865, but Colorado voters will soon have a  chance to end slavery in the state.

The language in Colorado’s constitution states that slavery is an acceptable form of punishment, according to CNN. 

There “shall never be in this state either slavery or involuntary servitude, except as a punishment for crime, whereof the party shall have been duly convicted,” Article II, Section 26 of the constitution reads.

Per CNN: “Amendment A will change the wording to ‘There shall never be in this state either slavery or involuntary servitude.'”

Organizations such as Abolish Slavery Colorado are urging voters to vote yes on Amendment A and, according to its website, wants to be the first state in the country “to remove this deeply offensive language from our Constitution.”

I hope that this puts forth the message that our past doesn’t have to be our future, that by and large we as Americans are interested in fixing our mistakes and that there’s hope for our future,” said Jumoke Emery, who works for the organization.

The U.S. Constitution, as well as over 15 state constitutions, allow slavery as punishment for a crime.

The amendment almost passed two years ago, but due to confusing language that was on the ballot, many people were unsure if they were voting for or against slavery, writes CNN.
