The march was part of the "National Day of Action for Immigrant Justice." It started from St. Mary's Church in the Central District of Seattle and ended at the Federal Building downtown. Marchers at the federal building were greeted by Mayor Greg Nickels and an assortment of entertainment and inspirational speeches.
The march's organization and its success relied on masses of informal networks including churches, community leaders, students, etc. from across the state, as well as formal organizations such as Comite Pro-Amnistia Y Justicia Social, Washington State Jobs With Justice, and the Northwest Immigrants Rights Project, among others.
