A quick look at Mardi Gras and its history. Traditionally, Fat Tuesday is the last day for Catholics to indulge since it is the last day before Ash Wednesday, which kicks off the season of Lent. Mardi Gras is filled with traditions, two of which came about in 1872, when the Russian Duke Romanoff visited New Orleans for Mardi Gras, they thought they would give him a royal reception and named him king for a day. A king and queen have been named every year since then. A second tradition is the colors of Mardi Gras which are also the colors of Romanoff House, which are purple, green, and gold. Good, quick review of Mardi Gras.
