In 1854, a runaway slave named Joshua Glover made his way to the free state of Wisconsin.  He was pursued by slave hunters and abducted in the middle of the night in Racine, leading to a group of over 5,000 people from Milwaukee and Racine coming together free Joshua from his imprisonment. Today on WTMJ Conversations, filmmaker Michael Jahr tells WTMJ's Libby Collins the breathtaking story of Joshua's betrayal by a friend, the riot that destroyed the courthouse imprisoning him, and how Joshua Glover's story led to the formation of the Republican Party and the election of Abraham Lincoln. It's all ahead on this historic edition of WTMJ Conversations!
