Labor Day was first celebrated in NYC in 1882 based on the celebrations of Canadian labor's Nine-hour movement.
Democratic president Grover Cleveland ordered 12,000 US Army troops commanded by General Nelson Miles (Soon to be the Commanding General US Army in 1895) against the strikers. 13 strikers were killed and 57 wounded before the strike was successfully broken.
Cleveland was now despised by labor, wanting reconciliation and fearful of further troubles, legislation designating Labor Day a national holiday were rushed through congress a mere 6 days after the end of the strike.
Now this story can be found on wikipedia, the History Channel website, the AFL-CIO website, and many others... but strangely enough not a word of it appears on the Department of Labor web page about Labor Day...
Go figger.
