Narodowa Organizacja Wojskowa (National Military Organization, NOW) was one of the Polish resistance movements in World War II.

Created in October 1939, it did not merge with the Service for Poland's Victory (SZP)/Union of Armed Struggle (ZWZ); later Home Army (AK).

On October 13, 1939, a few days after the end of the joint German and Soviet Invasion of Poland, a conspirational meeting of leaders of the National Party took place in Warsaw.

In the late 1940 and 1941, the Gestapo carried out mass arrests of members of the National Party in Lesser Poland, Pomerelia and Warsaw.

After this, the party had to re-create its depleted structures, and in September 1941, new leader of the SN, Stefan Sacha, named Colonel Jozef Rokicki new commandant of the NOW.

As a result, on August 23, 1942 an agreement was signed in which the National Military Organization was merged with the Home Army.

The new NOW was headed by Colonel Ignacy Oziewicz, and was divided into five districts: Radom, Kielce, Częstochowa, Podlasie, Lublin and Łódź.

In 1942, the new NOW merged with Military Organization Lizard Union, creating the National Armed Forces (Narodowe Sily Zbrojne, NSZ).

Weapons and ammunition were collected for the future uprising, a system of communication was created, underground press was distributed.

Until mid-1941, the NOW was divided into 14 districts: In the autumn of 1939, an envoy from the commander of the National People's Military Organisation reached Białystok.

On 31 October 1939, Zygmunt Hykiel set off as a representative of Białystok to Warsaw in order to establish contact with Szymon Poradowski.

The ZJ envoy, 2nd Lt. Feliks Mazurek, pseudonym "Zych", began talks with representatives of the Armed Confederation.

Leaving the area, he handed over his duties to Antoni Kozłowski "Bialy", but he soon moved to NOW "Roman" - August Michalowski.
