1792:
"The constitution and form of government, as proposed to be amended by a committee appointed by the House of delegates at the last session." (Annapolis:  Printed by Frederick Green, printer to the state, [1792]).
Introduced in the House of Delegates on December 26, 1791 by Gabriel Duvall.  Authored by a committee consisting of William Pinkney, Harford County; Gabriel Duvall, Annapolis; William Craik, Charles County; William Clagett, Washington County; John Francis Mercer, Anne Arundel County; John Griffith Worthington, Anne Arundel County; and James Tilghman, Talbot County.  On November 15, 1792, Duvall called for a list of yeas and nays on the question of whether members of the House would take into consideration the next day the several bills for amending and altering the constitution reported by the committee of November session last.   Not only did they vote to not consider the bills the next day, but they voted to not consider the bills at all that session.  The constitution was never ratified.

1904:
The "Poe" Amendment:  Introduced February 4, 1904 in the State Senate by John Gill, Jr.  Authored by John Prentiss Poe and Arthur Pue Gorman.  The "Poe Suffrage Amendment" sought to disenfranchise black voters in Maryland by introducing a grandfather clause and an "understanding" clause.  Critics charged that the amendment was unconstitutional, undemocratic and would undermine Maryland's entire way of government.  Republicans saw the measure as a partisan attempt to weaken their party.  White foreign-born citizens believed that the grandfather clause and the "understanding" requirement would work to against them as well as blacks.  Black voters organized the Negro Suffrage League and established chapters throughout the state in order to marshal opposition to the amendment.  As a result, voters defeated the Poe amendment at the polls by a significant margin.
