Yes, President Grover Cleveland did send federal troops to Seattle in 1886 in response to the anti-Chinese riot and the ensuing unrest. This intervention was part of the federal government's effort to restore order and protect the rights of Chinese immigrants, despite the widespread anti-Chinese sentiment at the time.

Background:

• In February 1886, a mob of white laborers and anti-Chinese agitators in Seattle attempted to forcibly expel the city's Chinese population. This was part of a broader wave of anti-Chinese violence in the western United States, fueled by economic competition and racial prejudice.

• The mob targeted Chinese residents, forcing them onto ships bound for San Francisco. Violence and intimidation were widespread, and the situation quickly escalated into a crisis.

Federal Intervention:

• Washington Territory's governor, Watson C. Squire, requested federal assistance to quell the violence and prevent further chaos.

• President Grover Cleveland, who was in his first term as president, authorized the deployment of federal troops to Seattle to restore order and protect the Chinese population.

• The troops arrived in Seattle and helped to stabilize the situation, ensuring that the remaining Chinese residents were not forcibly expelled and that the mob violence was brought under control.

Significance:

• The deployment of federal troops highlighted the federal government's role in enforcing laws and protecting minority groups, even in the face of local opposition.

• However, the broader anti-Chinese sentiment persisted, and many Chinese immigrants left Seattle voluntarily or were driven out in the aftermath of the riot.

This event is an important chapter in the history of Chinese immigration in the United States and reflects the tensions and challenges faced by Chinese communities during the late 19th century. If you'd like more details or sources on this topic, let me know!
