Eržvilkas (Samogitian: Eržvėlks) is a town in Taurage County, Lithuania. According to the 2011 census, the town has a population of 429 people.[1]
Before World War II and the Holocaust, the village had an important Jewish community. In 1923, they were 46% of the total population.
Among others, Hermann Schapira (1840-1898), a mathematician and important forerunner of the Zionist movement, was born in the village.
At the beginning of the Second World War there were 180 Jews living in the village.[2] [3]
In 1941 these Jews were exploited as forced labour.[4] In September 1941, they were murdered in mass executions perpetrated by an Einsatzgruppen of Lithuanian policemen at the Gryblaukis forest.[5]
