JUNETEENTH-EXPLAINER: Many Americans are celebrating Juneteenth, marking the day in 1865 when the last enslaved people in the U.S. learned they were free. For generations, Black Americans have recognized the end of one of history’s darkest chapters with joy, in the form of parades, street festivals, musical performances or cookouts. Four years after it became a federal holiday, there’s a push today for people to see beyond the revelry and learn about Juneteenth’s history. By TERRY TANG. With AP photos.

JUNETEENTH-SPONSORSHIPS: Juneteenth celebrations have scaled back due to funding gaps as companies and cities across the country retreat their support for diversity initiatives. By NADIA LATHAN. With AP photos, video.

JUNETEENTH-NATIVE TRIBES-FREEDMEN: While many across the country recognized Juneteenth as the end to the institution of slavery in America, some tribal nations in Oklahoma continued to own slaves until the following year, 1866. Today, many of the descendants of those formerly enslaved people are still fighting for full citizenship within those tribal nations.. By GRAHAM LEE BREWER. With AP photos and video.

Events include a celebration organized by the Black Heritage Trail of New Hampshire, a group formed in Portsmouth, where an enslaved woman successfully escaped George Washington’s pursuit.

There will also be a community performance of “Boots on the Ground,” a increasingly popular line dance among Black Americans. 11am ET. By HOLLY RAMER. With AP photos and video.
