However, the further development of water polo in Lviv was delayed due to the outbreak of the First World War.
One proponent of the sport was the teacher Ivan Viktorovich Vrzhesnevsky, who became the rector of the institute after the end of the war.
In the last pre-war championship of the Soviet Union, Kharkov water polo players won in the 2nd group.
In the post-war years, the main centers for the development of water polo in Ukraine were Kiev, Kharkov, Lvov, Sevastopol, and Uzhhorod.
In the 1970s, Kiev's Dynamo team won the silver and bronze medals of the championship of the USSR several times.
At the same time, the Water Polo Federation of Ukraine was created, which until 2005 operated without legal registration.
