Yiddish Letters
Yiddish letters can be found in several archives which were acquired by the IISH in the course of time. Some of these are from archives bought or deposited in the IISH after the coming to power of the German National-Socialist Party in 1933. The Institute was founded in 1935 to safeguard important archives and libraries of the leftist parties in Germany from destruction by the Nazis. Among these archives are that of the Menshevik leader Raphael Abramovič and the Russian Socialist-Revolutionary Party.
