"Glory to Ukraine! Glory to the heroes!" That is the slogan the Ukrainian military officially began using at the country's Independence Day parade on Friday, replacing the soviet-era "Wish you health, comrade!"
The phrase dates back to World War I, when military units from the short-lived Ukrainian People's Republic were fighting alongside German and Austro-Hungarian soldiers against Russia. However it was in the 1930s when it really took hold, becoming a rallying cry for the Organization of Ukrainian Nationalists (OUN), explained Oleksandr Zaitsev, a historian from the Ukrainian Catholic University in Lviv.

"There are records showing that during the court hearings against OUN's leader Stepan Bandera in 1936, his supporters were accompanying the slogan 'Glory to Ukraine' with a hand-throwing fascist-style salute," he told DW
