Which ratified a proposed amendment to the constitution

the state legislatures.

Explanation:

An amendment must receive a two-thirds majority vote from both the Senate and the House or be called for at a constitutional convention voted on by two-thirds of state legislatures. After this the amendment is taken to the state legislatures for a vote. The state legislatures are supposed to vote at least two-thirds of them for the amendment to be ratified and added to the constitution.

i confess that there are several parts of this constitution which i do not at present approve, but i am not sure i shall never approve them: for having lived long, i have experienced many instances of being obliged by better information or fuller consideration, to change opinions even on important subjects, which i once thought right, but found to be otherwise. it is therefore that the older i grow, the more apt i am to doubt my own judgment, and to pay more respect to the judgment of others.

most people were factory or company owners.
