The National Day of Solidarity with Muslim, Arab and South Asian Immigrants is observed in the United States every February 20. Established in the wake of the September 11 attacks, this day aims to support immigrant groups that have faced unjust treatment and discrimination, particularly those affected by anti-Muslim bias and racial profiling. The observance began in 2002, with endorsers encouraging participants to wear blue triangles, a symbol referencing the badges used in Nazi concentration camps. Organizations such as the American-Arab Anti-Discrimination Committee and South Asians Against Police Brutality and Racism were involved in promoting the day and forming the Blue Triangle Network for organizing events. While the network has since become defunct, the day serves as a reminder of the ongoing challenges faced by these communities and encourages individuals to advocate for equal treatment and justice. Activities may include organizing community events, supporting immigrant families, and participating in campaigns for fair treatment.
