Krewe of Cosmos is the oldest Mardis Krewe in Calcasieu Parish. It was founded in 1951 and was sponsored by the 50’s Club of Sulphur. This club was made up of members of the Knights of Columbus Council. In 1954 the group began calling itself the Krewe of Cosmos.
    The first King and Queen of the Ball were Dr. W.A.K. and Ilene Seale . They were crowned at the first pageant held at the Sulphur High gymnasium 1951. The krewe has grown to 225 due paying members and several lifetime members. The krewe members contribute their time and talents each year to produce the annual pageant and ball. 
        The pageant is a presentation of that year’s King and Queen and their Court.  But it is much more than that. Each year the members vote a theme for the following season. The members who will be serving on the court will design and make a unique costume that represents the theme of the pageant. The members spend countless hours building decorations and backdrops for the theme. They transform the auditorium into a fantasy world.

    Also included in the festivities are the merry makers of the ball, the Krewe of Cosmos “Jesters”. They work for months learning a dance routine that is presented at that year’s pageant. It is always a hilarious sight to watch. They visit local Nursing homes the Sunday after the ball handing out beads, dancing with residence and presenting there routine. The pageant is held the Saturday before Mardis Gras at the Sulphur High Auditorium and it is free to the public.    
    Directly after the pageant members and their invited guest attend the Krewe ball held at the Lake Charles Civic Center. It is also decorated in the theme of the year by dedicated members. The King, Queen and their court are again presented to the krewe members after which a good time is had by all.
  The Krewe participates in Lake Charles’ annual Mardis Gras children's parade and the Krewe of Krewe’s parade held on Mardis Gras day.  They throw beads, trinkets and candy to local parade goers.
    In 1991, Bob Landry started a new Cosmos tradition by walking in the parade by himself with a cane of flowers that he handed out to lady’s along the route. This group became known as the Krewe of Cosmos “Walkers”. They walk along the parade route handing out beads and the coveted Mardi Gras Flowers. Their cane of flowers are made of the Mardis Gras colors of purple, green and gold and are handed out to lady’s of all ages for a kiss on the cheek. 
     Other krewe activities during the year include the parade barbeque held the morning of the parade. A membership party in the fall, a farewell to the King, Queen and its Court held at the beginning of Mardis Gras season and the annual Krewe Crawfish Boil held in the Spring.
