Central Industrial Region (Poland)

Its goal was to create a heavy industrial center in the middle of the country, as far as possible from any borders, strengthen the Polish economy and reduce unemployment.

Most of those investments were located in regions with high unemployment, and their construction succeeded in reducing social tensions and began to strengthen the Polish economy.

The development of the COP and similar projects, like the construction of the seaport in Gdynia, were the most outstanding achievements of the Second Polish Republic, marking the beginning of the new era of recently regained independence.

Consequently, their contribution to the equipment of the Polish Army in the run-up to the war was relatively insignificant, and did little to offset the crushing material superiority of the German armed forces.

German encirclement and annihilation tactics in the Second World War, with their rapid advances by extremely well-equipped infantry (better than even their British and French counterparts) and fast motorized forces (heavy losses suffered by Panzer divisions were one of the reasons, the Germans created, what became known after World War II was over, as blitzkrieg tactics[1]) and long-range air attacks, ensured that the COP region apparently failed to provide a secure haven for Polish industry.

Melchior Wańkowicz, in his 1939 book Sztafeta, emphasized the fact that the quick growth of the COP's towns and cities was not followed by necessary investments in infrastructure, especially schools and housing.
