When we, Ukrainians, stood up to oligarchiat/mafia russian-puppet governing party in 2013-2014, what do you call this?

Protests that actually turned into a coup ? That doesn't seem to have happened in Brazil. (Yet.)

Discussion about would-be coups seems to be fraught... probably best to avoid the term ?? I'm remembering those funny (for an outsider) images of the January 6th USA Capitol invaders seemingly being lost at what they were supposed to be doing once in the building... (though this took a darker turn when we learned, much later, that Trump did not show up because his own security service prevented him to !)

I don't think so. It's just a political position. Those people would rather the military ruled over them.
