The International and State Defense Police (Portuguese: Polícia Internacional e de Defesa do Estado; PIDE) was a Portuguese security agency that existed during the Estado Novo regime of António de Oliveira Salazar. Formally, the main roles of the PIDE were the border, immigration and emigration control and internal and external State security. Over time, it came to be known for its secret police activities. PVDE was founded by Captain Agostinho Lourenço, who in 1956 would become the President of Interpol.
