In 1917, Lypa became the editor of the Odesskiy Vestnik [uk] magazine and published his first pamphlets: Liberation of Ukraine Union ("Soyuz vyzvolennia Ukrainy"), Kyivan Kingdom According to Bismarck’s Project ("Korolivstvo Kyivske za proektom Bismarka"), Wear your Awards ("Nosit svoi vidznaky") and Hetman Ivan Mazepa.

The group's members included the outstanding Ukrainian writers Leonid Mosendz, Natalia Livytska-Kholodna and Oleksa Stefanovych.

The young writers gathered to discuss and develop their literary works, incorporating the ideal of reviving the Ukrainian nation.

Yurii Lypa's second poetry book Severity ('Suvorist'), which was published in 1931, reflected this ideology, expressing faith in the Ukrainian nation's independent and prosperous future.

In 1934, Yurii Lypa's novel Cossacks in Moskovia ('Kozaky v Moskovii') was published in Warsaw, which was followed shortly by a collection of his literature essays, entitled Fight for Ukraine ('Biy za Ukrainu').

Perhaps Lypa's most well known political and philosophical work is his trilogy Cause of Ukraine ('Pryznachennya Ukrainy') (1938), The Black Sea Doctrine ('Tchornomorska doktryna') (1940) and The Severance of Russia ('Rozpodil Rosii') (1941).

In 1940, together with Ivan Shovhenivskyi, Valentyn Sadovsky, Lev Bykovskyi and Vadym Scherbakivskyi, Lypa founded the Ukrainian Chornomorskyi (Black Sea) Institute, a research body focused on the potential economic and political problems Ukraine would face if it gained independence.
