Dozens of protests are happening across Illinois today.

It's the same day a massive military parade is set to take to the streets of Washington in an elaborate showcase of troops, tanks, weapons and aircraft .

The parade, estimated to cost $40 million , coincides with both the U.S. Army's 250th anniversary and President Donald Trump's 79th birthday.

In response to the extravagantly costly display, a mobilization of "No Kings" protests have been organized nationwide.

Here's what you should know.

What are 'No Kings' protests?

The protests are being organized by a nonprofit coalition of progressive political action groups called Indivisible . The organizer's website describes "No Kings" as a "nationwide day of defiance" in response to Trump and the military parade, saying, "we’re taking action to reject authoritarianism."

With an emphasis on nonviolent activism, the website outlines the movement's broad appeal, "from city blocks to small towns," and makes a promise to battle Trump's "ego" in a fight for democracy.

"On June 14th, we’re showing up everywhere he isn’t – to say no thrones, no crowns, no kings," the website reads.
