After the 28 May 1926 coup d'état and the establishment of the military "Ditadura Nacional", the Preventive and State Security Police was disbanded. However, soon after, two similar agencies were created, the Lisbon Information Police and the Porto Information Police, respectively under the control of the civil governor of Lisbon and the civil governor of Porto. In 1928, the two agencies were merged into a single Information Police under the direct control of the Minister of the Interior. In the same year, the Portuguese International Police was created as a section of the Information Police, succeeding the former Emigration Police. In 1931, the Information Police was disbanded and the Portuguese International Police became autonomous, under the direct control of the Minister of the Interior. In 1932, the Political and Social Surveillance Section of the Portuguese International Police was created, with the same role of the former Information Police.
