Here are some organizations that promote nonviolence. Hope this helps!
from UNESCO website...
UNESCO Culture of Peace:
framework and rationale
"Because the year 2000 is the International Year for the Culture of Peace (UN Doc A/RES/52/15) and the period 2001-2010 is the International Decade for a Culture of Peace and Non-Violence for the Children of the World (UN Doc A/RES/53/25), there is no better time to join the global movement to educate for a sustainable culture of peace."
various mentions of nonviolence from the UN website...
United Nations Charter: origins
"In 1945, the United Nations was established to "save succeeding generations from the scourge of war", "to reaffirm faith in the …dignity and worth of the human person [and] in the equal rights of men and women", "to establish conditions under which justice and respect for the obligations arising from treaties and other sources of international law can be maintained", and "to promote social progress and better standards of life in larger freedom…". Peace education has developed as a means to achieve these goals. (Preamble to the UN Charter)"
Universal Declaration of Human Rights: origins
"Peace education is "directed to the full development of the human personality and to the strengthening of respect for human rights and fundamental freedoms". It promotes "understanding, tolerance and friendship among all nations, racial or religious groups" and furthers "the activities of the United Nations for the maintenance of peace." (Article 26, Universal Declaration of Human Rights)"
Ringing of the Peace Bell Ceremony
20 September 2002 at 10.00 AM
Check against delivery!
Mr. Secretary-General, distinguished colleagues, ladies and gentlemen,
It gives me great pleasure to join you this year, as we gather here to ring the peace bell and to celebrate the International Day of Peace and Global Ceasefire.
This special occasion allows us to remind ourselves of the primary mission of our organization - maintenance of world-wide peace and security. The people of the many nations who collected the coins to construct this bell show us that life in peace is a desire shared by people around the globe. Many of these people look to the United Nations for support in the peaceful settlement of disputes, in conflict resolution, post-conflict reconstruction and economic and social development. And indeed, throughout the years of its existence, the United Nations has helped to better the lives of many of these people.
I therefore wholeheartedly welcome the designation of 21 September as the international day of peace, nonviolence, and global cease-fire. The celebrations give us an opportunity to reflect on past accomplishments and draw inspiration for the work ahead as the United Nations General Assembly launches its deliberations. I also sincerely hope that this symbolic act can be accompanied by a commitment to a cease-fire by as many warring parties as possible.
In this way let the peace bell's ring resonate throughout the world by spreading tolerance, dignity, justice, understanding, solidarity, prosperity - in one word, by spreading peace.
