Yurii Lypa commenced work at the
University of Warsaw. Yurii Lypa's first poetry book, entitled
Serenity ('Svitlist'), was published in
Poland in 1925. In 1929, Yurii Lypa, together with Yevhen Malanyuk, established the literary group 'Tank'. 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'). In 1936,
Notebook ('Notatnyk'), comprising three volumes of the author's short stories, was published. The stories were mainly concerned with
Ukrainian War of Independence. The same year he produced the political works
Ukrainian Age ('Ukrainska doba') and
Ukrainian Race ('Ukrainska rasa'). 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). Following his father's steps, Yurii Lypa continued his medical practice. He specialised in
phytotherapy and was a great
phytotherapist. He also published the medical books:
Phytotherapy (‘Phytotherapy’) (1933),
Healing Herbs in Ancient and Modern Medicine (‘Tsilyushchi roslyny v davniy I sychasniy medytsyni’) (1937) and
The Cure Beneath Our Feet (‘Liky pid nohamy’) (1943). == Political activities ==
