The Ditadura Nacional (Portuguese pronunciation: [ditɐˈðuɾɐ nɐsiuˈnal], National Dictatorship) was the name given to the regime that governed Portugal from 1926, after the accession of General Óscar Carmona to the posts of Prime Minister and President, until 1933.

During this time no one clear leader emerged, as the dictatorship was led by a coalition of lower-rank military officers, some of whom were Integralists.

He was replaced by General Gomes da Costa, the leader of the 28 May coup, who became Prime Minister as well as President.

Gomes da Costa was not devoted to the establishment of a permanent military dictatorship, and as a result he was forced out on 9 July in a coup led by the unshakably authoritarian General António Óscar de Fragoso Carmona who assumed both of the highest offices of the state and seized dictatorial powers.

Salazar's influence began to grow at the expense of military officers who gradually lost their political power, with Roman Catholic religious institutes again permitted in Portugal.

The answer was provided by Salazar, who became Prime Minister on 5 July 1932 and in 1933 reorganized the regime as the Estado Novo.

A new Constitution was approved in a referendum, defining Portugal as a single-party corporative republic and multi-continental country (in Europe, Africa, Asia and Oceania).

[2] On that same day, a coup attempt started in Lisbon, led by Mendes dos Reis, Agatão Lança, Câmara Lente, and Filipe Mendes, with navy, GNR, and civil forces, as well as the decaying NRP Carvalho Araújo and Canhoeira Ibo.

[2] But the negotiations were hard and the government's forces learned about the plot and preemptively bombed São Jorge Castle, where the rebels were located.

[2][3] It was led by Hélder Ribeiro, Utra Machado, Jaime Batista, Dias Antunes, Sarmento Beires.
