After the eastern branch of the Siberia Railroad was constructed in the 19th century, many Jewish people came from Russia and other Eastern European regions to Harbin. When the Russian Revolution broke out in 1917, many more Jewish people arrived, and by 1920, there were more than 20,000 Jewish people in Harbin.
Harbin became an asylum for Jewish people during the Second World War.
After the War Jews resettled all over the world.
In 2006 the Harbin New Synagogue (built in1921) was restored as Harbin Jewish History
and Culture Museum.
