(CNN) It is one of American history's deadliest flashes of racial violence.
And yet, for 100 years it went virtually ignored.
Tulsa Oklahoma was the site of a race massacre. Beginning on May 31, 1921, White lynch mobs rioted and destroyed the city's Black Greenwood District, a vibrant commercial area also known as "Black Wall Street."
Accelerating the death and terror, rampaging White pilots dropped firebombs from planes. When the smoke cleared, the once-thriving 35-block district that boasted more than 300 Black businesses was smoldering ruins.
Official records list 36 deaths. But historians say the toll may be up to 300 people -- mostly Black people.
"In early Greenwood, you could find movie theaters and dance halls, pool halls, barber shops, beauty salons, hotels, rooming houses, confectionaries, jitney services, a haberdashery, laundries, restaurants, grocery stores -- all manner of small business, coupled with service providers. Doctors, lawyers, dentists ...," says Hannibal B. Johnson, author of "Black Wall Street 100: An American City Grapples With Its Historical Racial Trauma."
"It was much more of a 'Black Main Street' than a 'Black Wall Street.' It was not a financial and investment center. Rather, it was a small business and entrepreneurial sector created out of necessity, because of the segregation that dominated the state of Oklahoma and indeed, the United States of America during this period," Johnson added.
But after that 16-hour riot, it was all gone. Those that survived the massacre were left traumatized in a nation unwilling to acknowledge their stories and suffering. Financially, Greenwood suffered as well with more than one thousand homes and businesses destroyed, according to the Oklahoma Historical Society.
"It interrupted intergenerational transfer of wealth that might otherwise have occurred in Tulsa, Oklahoma -- which might otherwise have affected the trajectory of the community. Tulsa might have been something like what Atlanta is today, perceived as a Black mecca for economics and entrepreneurship," Johnson added.
Johnson, who is featured in CNN's "Dreamland: The Burning of Black Wall Street" documentary, says Black Wall Street peaked in the early to mid-1940s after the massacre.
"Even after this utter devastation, most people in the Greenwood community, most African Americans in Tulsa said to themselves and to their larger community, 'we shall not be moved.' And they rebounded and rebuilt and created an incarnation of Black Wall Street that would surpass its initial version."
There are several ways you can help uphold Greenwood's legacy and support Black entrepreneurship nationwide.
Founded in 2015, The 1921 Race Massacre Centennial Commission provides educational resources to raise awareness about Tulsa's historic Greenwood District.
"The idea by the Commission is to leverage the history of Tulsa's Greenwood district, to improve the district physically and make it rife with opportunities for economics in the community," says Johnson, who oversees the commission's educational initiatives.
The Commission's website offers downloadable lesson plans and curricula for educators. The commission also hosts an Educator Institute that trains instructors on how to teach Tulsa's racial history.
"We teach not just the substantive history, but pedagogy, how to teach the history in age-appropriate ways," added Johnson.
"We work with teachers to develop curricular supplementary material in the educators' institute which is very popular."
On June 2, 2021, the Commission will open the doors of Greenwood Rising. Positioned at the entrance of the Greenwood District, the historical site will serve as a landmark to honor the legacy of Black Wall Street before and after the Tulsa Race Massacre. The facility will also help patrons connect the dots between Tulsa's history and current race-based injustices in the US. On June 3, 2021, the Commission will host a national day of learning.

Built in 1905, the Historic Vernon African Methodist Episcopal Church stands as a testament to Black resilience.
On the bloody night of June 1, 1921, Black families found refuge in the church basement. White mobs destroyed the building -- but the basement survived.
According to the church's pastor, Reverend Dr. Robert Turner, his congregants now call this sacred space, "The Refuge Room."
In 1928, the church rebuilt, even bigger than before. Today, the church continues to thrive and serve Greenwood. During the coronavirus pandemic, the church served 340,000 meals and counting.
Reverend Dr. Turner also says his congregation has an active role in Oklahoma's current conversation on reparations.
Vernon African Methodist Episcopal Church created a Bless the Basement campaign to help preserve the church as a landmark memorizing the Black Wall Street era.
"My dream and hope for Vernon is to restore this historic church to her former glory, to respect the legacy of the survivors, who built this church out of the ashes -- and to make it a place of prayer to all nations as we seek to grow toward racial healing," says Turner, who is also featured in DREAMLAND.
