In its history, Maryland has had four constitutions. Each was adopted by a constitutional convention that was, at least in some regard, not permitted under the previous form of government. The first Maryland Constitution was adopted in 1776 by a self-proclaimed convention that was also the de facto government of the state. The second constitution was adopted in 1851 principally to reapportion the state legislature. In 1864, the third constitution was adopted and was concerned primarily with the issues of the Civil War - emancipation and preservation of the Union. The fourth constitution was adopted in 1867, soon after the Civil War and the changes made served largely to repudiate the 1864 constitution. The 1867 constitution continues in force but has been significantly amended particularly in response to the defeated constitutional convention of 1967. This work covers this history and analyzes each provision of the Maryland Constitution.
