Due to their unsatisfactory performance and the shift, under the corporatist Estado Novo regime of Oliveira Salazar, toward a stronger Portuguese control of Portuguese Empire's economy, the companies' concessions were not renewed when they ran out. This was what happened in 1942 with the Mozambique Company, which however continued to operate in the agricultural and commercial sectors as a corporation, and had already happened in 1929 with the termination of the Niassa Company's concession. In 1951, the Portuguese overseas colonies in Africa were rebranded as Overseas Provinces of Portugal.
