what basic principle of democratic government did the Magna Carta and the English Bill of Rights establish

When the First Continental Congress met in 1774 to draft a Declaration of Rights and Grievances against King George III, they asserted that the rights of the English colonists to life, liberty and property were guaranteed by “the principles of the English constitution,” a.k.a. Magna Carta.

regarding the law, the 15th amendment was specifically designed thinking in the rights of black free men.

even though ratified on february 3, 1870, the promise of the 15th amendment would not be fully applied for a long time.poll taxes and literacy tests would allow southern states disenfranchise african americans. only in 1965 the voting rights for african americans would be actually able to vote in the south.

in 1965, president johnson signed the voting rights act, which aimed to overcome legal barriers that prevented african americans from voting as it was guaranteed by the 15th amendment to the u.s. constitution.
