Armenia's recent successful uprising is being celebrated as unprecedented for a former Soviet state. The so-called “velvet revolution” began on the last day in March with a protest walk. It ended two weeks and 100km later with the government overthrown.

Yet revolutions rarely triumph.

In this Inquiry we look at the factors that need to come together for such a revolution to succeed. Do they always need to be bloody and brutal or can non-violence resistance be as effective? How important are state institutions like the military to determining success? And what role do international relationships have to play?
