Blue Hill Avenue will be fluttering with the familiar red and blue flag of Haiti this Sunday (May 21) as the 21st annual Haitian American United (HAU) Unity Parade, featuring floats from the Haitian Consulate, Haitian businesses, churches, and other organizations, marches from Mattapan Square to Talbot Avenue and Harambee Park to celebrate Haitian Heritage Month and Haitian Flag Day.

Wilner Auguste of HAU said they will start the Unity Parade at 1 p.m. sharp. The grand marshal will be Ruthzee Louijeune – the first Haitian American to sit on the City Council in Boston. The march will conclude at Harambee Park in Franklin Field, where there will be a food, performances, and the presentation of the L’Ouverture Scholarship.

“It’s a tremendous honor to be the grand marshal because this was a parade I attended every year as a kid and to be at the head of that parade now is so cool and such an honor,” said Louijeune.

“It’s an incredible weight to be responsive to all the needs of our community, but it’s also so meaningful to celebrate by marching up Blue Hill Avenue in my community where the Haitian community is firmly planted. Even with such crisis and chaos in Haiti now, there is still room to celebrate Haiti, its flag, and what it means to Black liberation worldwide…We are grounded in hope as the only option.”
