When 18-year-old Shalom Rokeach married 19-year-old Hannah Batya Penet in Israel on Tuesday, it was more than just a lavish wedding -- it was the launch of a new era. The groom is the future leader of the revered Belz Rebbe, a Hassidic Jewish sect that began in Poland in the early 1800s. More than 25,000 guests attended the hours-long ceremony, which was filled with traditional significance and lasted until dawn the next day. Though the bride was surrounded by thousands of well-wishers, she wore a heavy veil throughout the ceremony, keeping her face hidden from her guests. -- By Lylah M. Alphonse, Senior Editor, Yahoo!
