What is Mardi Gras and Carnival?
Mardi Gras and Carnival are among the world’s most spectacular celebrations, featuring parades, dazzling costumes, music, and a festive atmosphere before the Christian fasting season of Lent. Rooted in European traditions, these lively events have spread globally, each culture adding its own unique touch.

The History of Mardi Gras and Carnival
The origins of Mardi Gras and Carnival date back to ancient Roman festivals such as Saturnalia and Lupercalia, which celebrated fertility, excess, and the coming of spring. When Christianity spread, these traditions were absorbed into a period of indulgence before Lent, the 40-day fast leading up to Easter.
The word Carnival comes from the Latin carne vale, meaning "farewell to meat," signifying the last feast before the Lenten fast. Mardi Gras, meaning "Fat Tuesday" in French, refers to the final day of feasting before Ash Wednesday.
French explorers introduced Mardi Gras to Louisiana in the 17th century, where it developed into the extravagant celebrations seen today in New Orleans. Meanwhile, Portuguese and Spanish colonisers brought Carnival to Latin America and the Caribbean, where it remains a key cultural event.
