According to one early history of Labor Day, the event originated in connection with a General Assembly of the Knights of Labor convened in New York City in September 1882.[5] In connection with this clandestine Knights assembly, a public parade of various labor organizations was held on September 5 under the auspices of the Central Labor Union (CLU) of New York.[5] Secretary of the CLU Matthew Maguire is credited for first proposing that a national Labor Day holiday subsequently be held on the first Monday of each September in the aftermath of this successful public demonstration.[6]
