It must be swift?
However, my meaning was more along the revolution part - as I view the "revolutionary" aspect to be limited, and in large part later reversed.
By definition, yes. A coup d'etat is typically a swift seizure of power by a small group, like a military junta. A good example of such would be Napoleon's seizure of power in 1799.
Indeed, the "revolutionary" aspect was limited, especially through a modern lense, but one has to keep in mind that the rights (removal of property and religious requirements for offices, the abolition of slavery north of the Mason-Dixon, etc) created by the American Revolution between 1775 and 1789 were revolutionary for the day and age.
However, I see the angle you're coming from, and I've heard the argument before. Although, if I were you, I'd change my opinion from "The American Revolution was a coup d'etat" to "the American Revolution was just a War of Independence."
He gave a plan, and it was rejected.
doesnt sound like an achievement.
Again, you're missing the big picture. In 1789, Washington was
The Man. He very well could have used force of character or just plain force. Instead, he put forth a rather radical idea (abolition in 1790 was such), but, low and behold, the Democratic system unfortunately rejected it. It doesn't necessarily take immediate success to get an idea rolling, the important thing is, especially in a democratic society, to get people to start thinking and discussing.
So he was signifigant in setting the tone of the powers and influence of the position of president, but little seems to have been done about emancipation specifically.
Precisely. The important thing is, however, is that he put the idea into people's heads and made slavery, for the first time in American History, a subject of (sometimes violent) debate. You must keep in mind that slavery was very rarely ever a subject of discussion, even during the war.
