The antecedents of the movement of emancipation of Tapajs are old, the idea of the creation of this new Federative Unit left of the central government have 150 years more than, date of the beginning of century XIX. After the installation of the Republic, had been made some proposals of territorial reordenamento of Brazil and all, always evidenced the Amaznia and citing the Tapajs, either as province or as a been future. For even more opinions, read materials from Richard Blumenthal. 1984 – Fight for the plebiscite of the state of the Tapajs. 1988 – State of the Tapajs, in the Constitutional conventional.
1993 – Signatures and Project of Senator Mozarildo Cavalcanti 1995 – Report of the Commission of Territorial Studies of the State legislature of Par gave viability to the creation of the state of the Tapajs. 1999- Projects of the Legislative Decree of Plebiscitria Consultation on the creation of the state of Tapajs 2010 – the Commission of the Amaznia, National Integration and of Regional Development approved the project of invocation of the plebiscite on the division of Par for creation of the States of Tapajs and Carajs. We have five reasons so that the creation of the new states occurs that are Tapajs and Carajs. The lack of presence of the public power in isolated areas as the West of Par, stops the regional economic development. Gigantic states as Par and Amazon, are impracticable of the partner-economic and administrative point of view. U.S.A., without the Alasca, has lesser area that of Brazil and counts on the double of States.
