"May Day", aside from being the ancient European religious festival of Beltane and other names, has been marked as "International Workers Day" for well over a century. If anything it's a populist theme, dating from a worker uprising of 1882:
The
Haymarket affair (also known as the
Haymarket massacre or
Haymarket riot) was the aftermath of a bombing that took place at a labor demonstration on Tuesday May 4, 1886, at Haymarket Square
[2] in
Chicago. It began as a peaceful rally in support of workers
striking for an eight-hour day and
in reaction to the killing of several workers the previous day by the police. An unknown person threw a dynamite bomb at
police as they acted to disperse the public meeting. The bomb blast and ensuing gunfire resulted in the deaths of seven police officers and at least four civilians; scores of others were wounded.
In the internationally publicized legal proceedings that followed, eight
anarchists were convicted of
conspiracy. The evidence was that one of the defendants may have built the bomb, but none of those on trial had thrown it.
[3][4][5][6] Seven were sentenced to death and one to a term of 15 years in prison. The death sentences of two of the defendants were
commuted by Illinois governor
Richard J. Oglesby to terms of life in prison, and another committed suicide in jail rather than face the gallows. The other four were hanged on November 11, 1887. In 1893, Illinois' new governor
John Peter Altgeld pardoned the remaining defendants and criticized the trial.
The Haymarket affair is generally considered significant as the origin of international
May Day observances for workers.
[7][8] The site of the incident was designated a
Chicago Landmark in 1992,
[9] and a public sculpture was dedicated there in 2004. In addition, the
Haymarket Martyrs' Monument at the defendants' burial site in nearby Forest Park was designated a
National Historic Landmark in 1997.

"No single event has influenced the history of labor in Illinois, the United States, and even the world, more than the Chicago Haymarket Affair. It began with a rally on May 4, 1886, but the consequences are still being felt today. Although the rally is included in American history textbooks, very few present the event accurately or point out its significance," according to labor studies professor William J. Adelman.

In the 19th century with unbridled and unrestrained robber-baron capitalism exploiting workers with extreme working hours, child labor and little regard to working conditions or safety, with hired thugs waging small-scale slaughter on workers who dared stand up for their own rights, strikes, demonstrations and eventually riots became commonplace. This is the messy side of democratic discourse, and is the entire reason we ever came up with things we now take for granted a 40-hour work week, child labor laws and any attention at all to safety in the workplace. That's where May Day comes from. It wasn't going to happen without a struggle.
Not that all that applies to the present goings-on in Seattle, but some may think it does, and like Haymarket, there are always destructive elements in any demonstration that will seek to convert orderly demonstration to chaos.
