This is truly unprecedented. For perspective, the largest march on DC during the Vietnam War was 500,000. Adjusted for population, that would be 784,411 people.<p>Estimated crowd in DC on Saturday was 1.2 million. Nationwide, it was 3 million. Just one of the six Los Angeles area protests had 750,000 people.<p>Even Witchita, Kansas had thousands.<p>I've never seen anything like this, and it's just the beginning.
Earth Day 1970 was the largest protest across the whole world, at 20 million. (<a href="http://www.earthday.org/about/the-history-of-earth-day/" rel="nofollow">http://www.earthday.org/about/the-history-of-earth-day/</a>)
I can't find how many protested in Earth Day 1970 just in the US.<p>This one will definitely be in the history books, though.
I was curious and checked <a href="https://en.wikipedia.org/wiki/List_of_largest_peaceful_gatherings_in_history" rel="nofollow">https://en.wikipedia.org/wiki/List_of_largest_peaceful_gathe...</a>. It includes all gatherings of people, not just marches or demonstrations.<p>I was impressed by the numbers of some of the top gatherings. The shared record is for two religious events at ~30 million people in India and Iraq.
