The idea of Ohio Violence Week was developed by the Mahoning Valley Sojourn to the Past, an organization that advocates for peace, tolerance and understanding in the community. In 2009, Sojourn students designed a non-violence week for Youngstown schools hosting a non-violence workshop and public service announcements based on the principles of non-violence. Students also designed and sold over 1700 non-violence t-shirts, leading the Youngstown Mayor and City Council to pass a resolution declaring the week of October 2-8, 2009 Non-violence Week in the city. Today, Nonviolence Week in Youngstown is a large community event marked with a rally and a parade. In 2012, over 500 people participated.
The first full week of October is designated "Nonviolence Week." (Ohio Revised Code 5.2289 Nonviolence Week. Added by 130th General Assembly File No. 28, SB 38, §1, eff. 10/11/2013.)
In 2021 Nonviolence Week in Ohio in USA falls on October 4.
