(CNN)Rallies, peaceful marches and celebrations commemorating Juneteenth occurred across the United States on Friday, bringing together countless Americans in remembrance as the nation confronts a history saturated with systemic racism and injustice.

Juneteenth, known as the oldest celebration of the end of slavery in the United States, is not yet a US national holiday. While it has been celebrated by Black Americans for over 150 years, states, cities and universities around the country have begun to acknowledge the often-overlooked date as one that deserves greater recognition.

People participate in a march in Brooklyn for both Black Lives Matter and to commemorate the 155th anniversary of Juneteenth on June 19, 2020 in New York City.

"The movements led by African American people changed this country to the core and will continue to. So, this is just a beginning to acknowledge this holiday, but we have a lot more to do," de Blasio said.
In Washington, DC, Mayor Muriel Bowser issued a proclamation recognizing June 19 as "Juneteenth Day" in the nation's capital, calling this year's celebrations "particularly significant as Black Lives Matter demonstrations happen across all 50 American states and around the world to protest centuries of police brutality and systemic racism against African Americans."
