Imagine all the people living life in peace. You may say I’m a dreamer, but I’m not the only one. I hope someday you’ll join us, and the world will be as one.
- John Lennon
John Lennon was known for his political activism and his anti-war views. He and Yoko Ono famously staged a week-long “bed-in for peace” in 1969, during which they invited members of the media to their hotel room to promote their message of peace.
