I just ran across this excellent video tracing the history of Sephardic Jews from the expulsion to the modern-day Balkans (in Spanish with English subtitles). To me, this is the most fascinating chapters in Jewish history, as I am have always been interested in my own possible Sephardic roots. As I learned at the IAJGS conference last summer here in Boston, many of those of us consider who consider ourselves entirely Ashkenazi may soon find out, through the advent of genetic genealogy, that we have stronger connections to Sephardic Jews than we ever imagined.
The video also speaks to the important concept of convivencia, which departed with the Jews when they left during the Expulsion, but which they continued to carry with them.
