Saint Patrick is NOT the patron saint of Evacuation Day. The actual reason why people marched in Boston on March 17th.
And Saint Patrick isn't just the patron saint of Ireland, but also of engineers and Nigerians.
Did anyone invite them to the parade?
Back on March 17, 1776 the word "Saint Patrick" was a passcode during a military conflict on Dorchester Heights and it's the same day that British sympathizers had to "evacuate" Boston.
Sorry, no luck of the Irish. Just a coincidence that a long planned military strategy that happened to be executed on March 17th.
In fact the first parade in 1901 was referenced as an Evacuation Day Procession.
To fill in the void that the parade has nothing to do with Saint Patrick, the parade has plenty of politicians and corporate sponsors though.
The country of Ireland didn't have a parade until 1995, and that was to " began a large-scale campaign to market St. Patrick’s Day as a way of driving tourism and showcasing Ireland’s many charms to the rest of the world." I guess American tourists were dissapointed that there no parades!
