The wedding broom is popular amongst both the Celtic diaspora and the African diaspora. They are also very common in Pagan handfastings. Before jumping the broom, they swept away the negativity from the past to give their union a fresh and positive start.
"The practice of jumping the broom started in slave times, when it was actually illegal for slaves to marry."--Early in our reading, a love interest of Cicero's talks about jumping the broom. As we see, this tradition has lasted to this day.
