Magna Carta did not emerge de novo in its fully fledged state in the late spring of 1215. The list of baronial demands, made on behalf of the kingdom as a whole, were born out of grievances that, in some cases, dated back more than a century. University of New Hampshire Professor of History David Bachrach discusses several key clauses of the Magna Carta as well as why this document was a touchstone for major political change.
