PORTSMOUTH, N.H.>> Juneteenth celebrations unfolded across the U.S. on Thursday, marking the day in 1865 when Union soldiers brought the news of freedom to enslaved Black people in Texas and attracting participants who said current events strengthened their resolve to be heard.

The holiday has been celebrated by Black Americans for generations, but became more widely observed after being designated a federal holiday in 2021 by former President Joe Biden, who attended an event in Galveston, the holiday’s birthplace.

The celebrations come as President Donald Trump’s administration has worked to ban diversity, equity and inclusion initiatives, or DEI, in the federal government and remove content about Black American history from federal websites. Trump’s travel ban on visitors from select countries has also led to bitter national debate.

In Portsmouth, N.H., Robert Reid waved a large Juneteeth flag at the city’s African Burying Ground Memorial Park, where African drummers and dancers led the crowd in song and dance. Reid, 60, said he attended in part to stand against what he called Trump’s “divide and conquer” approach.

“It’s time for people to get pulled together instead of separated,” he said.

Jordyn Sorapuru, 18, visiting New Hampshire from California, called the large turnout a “beautiful thing.”

“It’s nice to be celebrated every once in a while, especially in the political climate right now,” she said.

The holiday to mark the end of slavery in the U.S. goes back to an order issued on June 19, 1865, as Union troops arrived in Galveston at the end of the Civil War. General Order No. 3 declared that all enslaved people in the state were free and had “absolute equality.”

Juneteenth is recognized at least as an observance in every state, and nearly 30 states and Washington, D.C., have designated it as a permanent paid or legal holiday through legislation or executive action.

In Fort Worth, Texas, about 2,500 people participated in Opal Lee’s annual Juneteenth walk. The 98-year-old Lee, known as the “grandmother of Juneteenth” for the years she spent advocating to make the day a federal holiday, was recently hospitalized and didn’t participate in public this year. But her granddaughter, Dione Sims, said Lee was “in good spirits.”

During a Juneteenth speech in Maryland, Gov. Wes Moore announced pardons for 6,938 cases of simple marijuana possession, which can hinder employment and educational opportunities and have disproportionally affected the Black community.

Moore, a Democrat who is Maryland’s first Black governor and the only Black governor currently serving, last year ordered tens of thousands of pardons for marijuana possession. The newly announced pardons weren’t included in that initial announcement because they’d been incorrectly coded.

In New Hampshire, Thursday’s gathering capped nearly two weeks of events organized by the Black History Trail of New Hampshire aimed at both celebrating Juneteenth and highlighting contradictions in the familiar narratives about the nation’s founding fathers ahead of next year’s 250th anniversary of the signing of the Declaration of Independence.

“In a time when efforts to suppress Black history are on the rise, and by extension, to suppress American history, we stand firm in the truth,” said JerriAnne Boggis, the Heritage Trail’s executive director. “This is not just Black history, it is all of our history.”

Later Thursday Trump complained on his social media site about “too many non-working holidays” and said it is “costing our Country $BILLIONS OF DOLLARS to keep all of these businesses closed.” Most retailers are open on Juneteenth, while federal workers generally get a day off because the government is closed.
