DC has never had true autonomy. In the Capitol City of the greatest democracy in the world, DC Citizens have always been denied self-determination via representation in government.
During its history, DC has experienced different levels of participation but since after the 15th Amendment was ratified (giving African-American men the right to vote), DC has not had any voting representation in the US Congress nor have they ever had full autonomy over their own local laws.
The full promise of America has always been denied in the City’s Capitol.
Explicit racism has always been used as a major argument for not allowing DC Citizens to vote, even though DC Citizens fought in wars, paid taxes, and were full members of the American experiment in Democracy.
In 1973, DC Citizens were granted the right to have an elected Mayor, City Council, and Advisory Neighborhood Commissioners, however Congress still retained full plenary powers, and has interfered with the voice of the people on many occasions.
