The Krewe of Karencro began as a Masquerade Dance to benefit the Carencro Boy Scout Troop 143 in 1973. The parents of the scouts did all of the work – decorating, clean up, making capes and crowns for the King and Queen, flags, etc. The bartenders and waiters were older scouts and fathers.

In those days, the King wore a tuxedo with a royal blue cape and a homemade crown and scepter. The Queen wore any kind of formal gown she chose. The Krewe members and guests were in costume or regular clothes.

There was stiff competition between parents and groups for the best costume. Much planning and work was done in secret so that no one else would know what their costume would be.

In 1980, the Krewe of Karencro was incorporated with six memberships. The first King and Queen Mardi Gras Ball was held in 1981 at St. Peter's Church Hall in Carencro. The Masquerade party was still held a week before the Ball.

During the first years the King and Queen were kept secret until they were crowned at the Brunch. In 1987, the Ball was moved from Carencro to the Holidome in Lafayette.
