For millennia, the idea of the lost tribes of Israel has been a topic of intrigue for believers and non-believers alike. There is certainly no debate that following the destruction of the First Temple, most of the 12 tribes have been scattered across the globe. From the words of Israel's prophets to the tales of the Sambation River to this day, the question remains: Where did they go? Well, that was anyone's best guess ?" until today. There is a group of people looking to uncover the truth behind the lost tribes in order to determine where they went and to integrate them back into the Jewish people. What makes someone lost? That is the first question to explore. It appears there are three types of "lost" Jews: those claiming to be descendants of biblical tribes; those who converted decades or centuries ago; and those who have been forced to hide their Judaism due to fears of persecution.
