this area had sworn allegiance to the new government, the seat of the local powers was changed to El Fuerte, Sinaloa. On 31 October 1825, the Constitution was reestablished, but Arizpe was not renamed a municipality since it did not meet the at least three thousand inhabitants required for the appointment. Six years later, in 1831, by a new Constitution, it was determined that the state be divided into parties. Eight parties were created including the Arizpe Party; on 13 April 1832, by a third order, it was commanded that the capital be returned to Arizpe, remaining as capital until the end of 1838, when Ures was established as its successor. In 1837 the state division was made up of districts planned by the agreement of the Departmental Board, and in the same way the District of Arizpe was created, and thus lasted until 1914, when on 21 November of that year the provisional constitutionalist governor Benjamín G. Hill decreed the abolition of the districts as part of the formation process of free municipalities during the Mexican Revolution and the structure of the local governments was managed. On 15 September 1917, Arizpe was named as a free municipality along with 66 others, and it was ruled by a municipal president and four councilors. The division into districts previously abolished was preserved only for political, electoral and finance purposes, and the Arizpe District was made up of the municipalities of: Aconchi, Agua Prieta , Bacoachi, Baviácora, Cananea, Fronteras, Huépac, San Felipe, Naco and Banámichi. In 1930 the municipalities of Banámichi and Baviácora were suppressed due to the low income they generated, and their localities were part of the municipality of Arizpe until 13 May 1931, when they were rehabilitated as independent municipalities back, and they remain so until today.
