Race riots in Philadelphia during the 1919 Red Summer

There were a number of race riots in Philadelphia during the 1919 Red Summer.

Background
As more and more African-Americans moved from the south to the industrial north, they started to move into predominantly white neighborhoods. In 1918, for four days starting July 25, there was a race riot in Chester and Philadelphia. When things finally settled down, 3 black and 2 white people had died from their injuries.

May 1919
In Philadelphia, the black migration created very high tensions in the area surrounding Twenty-fifth and Pine streets. Making things worse, a local gang had been terrorizing the new black tenants. On May 9, a large mob of white people clashed with a large black group. The mob then broke open the door at 2535 Pine street and tried to eject George Grahm and his black family who had moved there a week earlier. A number of people were later arrested.

July 1919
The New York Times wrote an article that described two riots during the Red Summer, one on July 7 and 31. Authors Rucker & Upton talk about during a carnival, a large group of whites fought a group of blacks. The violence was quickly suppressed when over 100 police showed up and made arrests.

Aftermath
This uprising was one of several incidents of civil unrest that took place during the so-called Red Summer of 1919. The Summer consisted of terrorist attacks on black communities, and white oppression, in over three dozen cities and counties. In most cases, white mobs attacked African-American neighborhoods. In some cases, black community groups resisted the attacks, especially in Chicago and Washington, D.C. Most deaths occurred in rural areas during events like the Elaine Massacre in Arkansas, where an estimated 100 to 240 black people and 5 white people were killed. Also occurring in 1919 were the Chicago Race Riot and Washington D.C. race riot which killed 38 and 39 people respectively, with both events having many more non-fatal injuries and extensive property damage reaching millions of dollars.
