A year after the 1935 death of Polish dictator MarshalJózef Piłsudski, in mid-1936, one of his followers, MarshalEdward Rydz-Śmigły, attempted to unite the various Sanation factions under his leadership. He failed in this, since another Sanation politician, PresidentIgnacy Mościcki, likewise had a large following; nevertheless, substantial numbers did throw their lot in with Rydz-Śmigły.
On February 21, 1937, diplomat and Colonel Adam Koc formally announced the formation of OZN. Its stated aims were to improve Poland's national defense and to safeguard the April 1935 Constitution. OZN was strongly pro-military, and its politicians sought to portray Marshal Rydz-Śmigły as Marshal Józef Piłsudski's heir, describing Rydz-Śmigły as the "second person in the country" after President Mościcki—a claim that had no foundation in the Polish Constitution.
