"Fat Tuesday” marks the final day of Mardi Gras festivities in New Orleans, though Carnival revelry has been in full swing in the Big Easy for weeks.

Merrymakers from near and far have poured into the city’s historic streets since January 6 for this year’s celebrations, many dressing in costumes, wearing masks or donning the iconic strands of purple, green and gold beads. An estimated 1.4 million people fill the coastal city each year for Mardi Gras to party and celebrate before Ash Wednesday arrives — and with it, 40 days of Lent.

Amid the wild outfits, “go” cups and flying trinkets, two krewes – or social clubs – have made bold statements on the parade route this year: One social club has defended their historic use of black makeup as blackface controversies continue to rock headlines, while another group of loyal New Orleans Saints has made waves for mocking the NFL over the now-infamous “no-call” during the Jan. 20 NFC Championship game.

Reps for the Zulu Social Aid & Pleasure Club have publically spoken out in defense of their tradition of wearing black makeup during Mardi Gras parades, even as blackface scandals involving Virginia Gov. Ralph Northam and attorney general Mark Herring have sparked heated debate.

The krewe argued that their attire bears no resemblance to those worn by “blackface” minstrel performers at the turn of the century, and that their costumes are designed to honor garments worn by South African Zulu warriors.

“Those who incorrectly compare our use of black makeup to ‘blackface’ minstrelsy can first look to our name to dispel that notion,” Zulu spokesman Clarence Becknell told WGNO before Mardi Gras. “Unlike minstrelsy, which was designed to ridicule and mock black people, the founders of our Social Aid & Pleasure Club chose the name ‘Zulu’ to honor their African ancestry and the continent’s most fierce warriors.”

The Zulu krewe continued to parade in their traditional costumes and black makeup this year, as evidenced in videos shared to social media.

Meanwhile, Krewe d'Etat made the most of their Mardi Gras spotlight to troll the NFL and commissioner Roger Goodell, dressed as “Robbin’ Refs” on their float named “Willful Blindness.” Their stunt referenced the divisive “no-call” in the NFC Championship game between the Saints and the Los Angeles Ram that some fans argue unfairly locked NOLA's team out of Super Bowl LIII.

Footage of their fun has since gone viral on Twitter, racking up hundreds of thousands of views.

The Mardi Gras party is expected to continue through midnight, when police on horseback ride down Bourbon Street to ceremonially “clear” the street — a symbol meant to mark the end of the Carnival season. Wednesday will then mark the beginning of Lent, which for many Christians is observed as a period of fasting and reflection ahead of Easter.
