For some reason, the current time-line points towards this having happened during 2014CE, but, I was fairly certain that I learned about it some time closer to maybe around 2009CE, because, I KNOW for a FACT that I had learned about it BEFORE I had moved to Hot Springs (South Dakota) from Bellevue (Washington) which happened during the year 2012CE for this time-line...

...leaving me to conclude that it is yet another one of those «Mandela-Effects» (which CANNOT be due to «mis-remembering» for a variety of reasons). Alas, who-ever seems to be involved in what I can only really describe as and translate into human-conceptual frame-works with maybe what could be called «time-manipulation.over-write» seems to really be working hard, over-time even, just to try to maintain materialist-oriented «narrative-control» over what constitutes «reality» and apparently wants to «dismiss» the suppressed truths as «mis-remembering» or «that's just your imagination» or «impossible» or making the bold claim that «there's no evidence» and all sorts of myriads of logical-fallacies that any sufficiently «evolved» consciousness would recognise as astro-turfing...

Possibility 1: Some being is manipulating an existing timeline, which would mean that that being owns the timeline and therefore every other being on that timeline. In that regard, it would be an omnipotent being, because if something happens that this being doesn't like, it could just change the timeline to its liking.

Possibility 2: Nature works differently. There are many timelines, connected in a tree structure. Remote viewing proves that consciousness can traverse this tree. The Mandela Effect is the slowly returning ability to "remember" (remote view) different timelines that all exist side by side.

Possibility 3: There are no timelines and someone is messing with your externally stored memories.

I personally don't remember the Maidan Revolution happening before 2014.
