ONAD is acronym for Organization for Nonviolence and Development

(formerly known as SONAD Sudanese Organization for Nonviolence and Development).

SONAD was founded in 1994 in Khartoum at the peak of civil war. It started as an initiative of South Sudanese students among internally displaced persons. It was legally registered in 2004 with the Federal Ministry of Humanitarian Affairs as a voluntary non-profitable organization.

When the Comprehensive Peace Agreement was signed in 2005, the organization extended its work to South Sudan and re-registered with Ministry of Legal Affairs and Constitutional Development  in Juba. On 9. November 2011, the organization changed its name from SONAD to ONAD by dropping "Sudanese", as reference to Sudan is no longer appropriate for a national organization operating in our new country - South Sudan.
