According to Rashbam (cited in Tosafos to Avodah Zarah 9b, s.v. האי מאן), the second Beis Hamikdash was destroyed 171 years before the end of the fourth millennium (3829 since Creation).


1654-1825 (171 years) The first Jewish settlers, 23 in all, came to New Amsterdam, New York. Throughout this long period the numbers were small and assimilation was most common. By the time of the American Revolution there were Jews in all 13 colonies. They were mostly Sephardic and German Jews totaling only 1,500 by 1790.

    Related to this: during those 171 years there were only Sephardic shuls in America. The first Ashkenazic congregation (Bnei Jeschurun, in New York) was founded in 1825.
