race riots in which whites attacked Black communities, sometimes with the assistance of local authorities. As a booming oil city, Tulsa also supported a large number of affluent, educated, and professional African-American residents. Greenwood was a district in Tulsa that was organized in 1906 following Booker T. Washington's 1905 tour of Arkansas, Indian Territory, and Oklahoma. It was a namesake of the Greenwood District which Washington had established as his own district in Tuskegee, Alabama, five years earlier.

The two likely knew each other at least by sight because Rowland would have regularly ridden in Page's elevator on his way to and from the restroom. A clerk at Renberg's, a clothing store on the first floor of the Drexel, heard what sounded like a woman's scream and saw a young Black man rushing from the building. The clerk went to the elevator and found Page in a distraught state. Thinking that she had been sexually assaulted, he summoned the authorities. Apart from the clerk's interpretation that Rowland had attempted to rape Page, many explanations have been given for the incident, with the most common explanation being that Rowland tripped as he got
