How did the constitution of 1866 restrict the rights of freed peiple

The Constitution of 1866 was invalidated after Radical Republicans took control of the U.S. Congress and imposed military governments on the former Confederate states. The new document declared the U.S. Constitution the supreme law of the land. Slavery was abolished and equality of the law was extended to all persons.

After some bitter wrangling, the 1866 Constitution Convention emerged with a document that declared the Ordinance of Secession null and void, agreed to the abolition of slavery, provided for some civil rights for freedmen (though not the right to vote or hold office), and repudiated all war debt.
