Can someone list down the events that occurred eventually leading to the formation of Uttarakhand?

Im researching the formation of Uttarakhand and would appreciate any piece of information on the protests, movement, aftermath, UKD, or related topics. I don't wanna miss on anything important. Please share relevant details, personal anecdotes, or credible online sources. I may not respond to each comment, but I'll value every contribution. Thank you!
