Mardi Gras, the Mullen Gala Story
Understanding the history of Mullen High School and how that shaped who we are as a community is essential. Mullen High School has celebrated Mardi Gras for 65 years. “The history of Mardi Gras dates back thousands of years. As Christianity spread, it acted as a time for indulging in rich foods before Lent began on Ash Wednesday, marking the start of fasting” (History.com Editors, 2025). As Christianity expanded, larger Roman Catholic populations around the world embraced the celebration. Some of the most famous places for Mardi Gras include Brazil, Venice, and New Orleans, which draw in thousands of tourists for the festivities (History.com Editors, 2025).Read More -
