The Underground Railroad was a massive effort by both enslaved and free people in the 19th century to secretly bring thousands to freedom in the North. This thought-provoking volume will fill readers with awe for the brave "conductors" and "passengers" involved with the Railroad. They'll learn about many of the safe havens, called "depots," that housed freedom seekers and the secret passages within them that hid the enslaved from their pursuers. Information about the time and biographies of figures vital to the Underground Railroad reinforce key parts of the elementary social studies curriculum.
