45th annual Peace Day celebration in Daley Plaza

CHICAGO (CBS) -- Hundreds gathered at Daley Plaza on Monday for an afternoon of music and dancing as part of the 45th annual Peace Day Chicago celebration.

Peace Day was started in 1978 by The Peace School, a nonprofit that helps people of all ages practice peace through classes such as meditation, yoga, taekwondo, and more.

The annual event encourages people to become peacemakers in their own communities, and to celebrate unity and diversity.

"As we continue to witness war and strife in places like Ukraine, and so many other nations, we need to be reminded that we play a part in our global communities," Mayor Brandon Johnson said at Monday's celebration.

The free event included live music and performances along with a call-and-response for peace in every country of the world.
