Vincentas Juška was born to a peasant family on 28 November 1860 in the village of Rubikai [lt], which at that time belonged to the Kovno Governorate of the Russian Empire.

In 1892 the Governorate-General of Vilno Ivan Kakhanov [ru] sentenced him to 14 days of arrest for illegal distribution.

After the coronation of Nicholas II and Alexandra Feodorovna, a manifesto was published that expressed the gratitude of the monarch to the inhabitants of Moscow.

He would secretly travel to Žemaičių Kalvarija to collect books to smuggle back into Riga's local Lithuanian inhabitants.

He participated in the 1905 Russian Revolution, where he distributed the social democratic press and gave anti-war speeches.

To avoid arrest, Juška moved to the United States, where he worked in a coal mine.
