The expansion of political participation in the southern U.S. states has come about largely because of federal government intervention.
Federal intervention is a power attributed to the federal government of Argentina, by which it takes control of a province in certain extreme cases. Intervention is declared by the President with the assent of the National Congress.
Article 6 of the Argentine Constitution states:
Upon intervention, the branches of the provincial government are dissolved, and the federal government must appoint a new authority (called intervenor) who will serve for a short term until the situation is normalized.
