The construction of the COP was initiated by the deputy prime minister for economic affairs, and at the same time the Minister of the Treasury Eugeniusz Kwiatkowski, who started operations in a difficult period, when the crisis was just about to end, unemployment in cities increased, and the situation was still very difficult in the villages.

​

Industrial production slowly increased, but its level was far from pre-crisis, due to the low purchasing power of the village. Kwiatkowski decided that the best solution would be to increase employment in industry, because there were no real opportunities for rapid changes in the agrarian structure. In line with the prevailing economic views initiated by the American New Deal, efforts were made to focus on the development of manufacturing in those branches of industry that did not contribute to the generation of consumer goods. Therefore, the emphasis was put on the development of the infrastructure. To this end, the Minister of the Treasury together with Paweł Kosieradzki and Władysław Kosieradzki developed a four-year investment plan, covering the period from July 1, 1936 to June 30, 1940. In the first version, the investments were to be carried out across the country, but due to limited resources and limited benefits from scattered investments it was decided to modify the plan. Kwiatkowski suggested concentration of treatments in the so-called security triangle in the south of Poland. He expressed his opinion in a Sejm speech on 5 February 1937, during which he also applied for the extension of the capital earmarked for this purpose to PLN 2,400 million, for which he obtained the consent. This is how the idea of ​​COP was born.
