After the 1933 rise of Salazar's dictatorial Estado Novo regime, suppression of the party grew. Many members were arrested, tortured, and executed. Many were sent to the Tarrafal concentration camp in the Cape Verde Islands. This included Bento Gonçalves, who would die there. The vast wave of arrests led to a major re-organization in 1940 and 1941, named the "Reorganization of '40". The first congress held after these changes was held in 1943, and stated that the party should unite with all those who also wanted an end to the dictatorship. Another important conclusion was the need to increase the party's influence inside the Portuguese army. The party was able, for the first time, to assure a strong clandestine organization, with a network of clandestine cadres, which would significantly aid the resistance against Salazar's regime.
