Maryland Democrats had regained control of the state legislature from the Unconditional Unionists in late 1866 and had immediately set out to reform the detested Constitution of 1864. In April 1867, a referendum on a constitutional convention was passed easily and 118 delegates chosen, every one of them a Democrat. The convention met for the first time in early May 1867 and worked through the summer. On this day, the convention completed its work and prepared the document for a confirmation by popular vote, to be held the next month. The vote was heavily in favor and the Constitution of 1867 remains in the twenty-first century as Maryland's ruling document. (By John Osborne)
