The Ottawa Convention banning anti-personnel landmines resulted from unprecedented close cooperation between civil society organizations and like minded governments concerned about the issue. Started by non-governmental organizations - that had seen first hand the devastating effects of anti-personnel mines - the call to ban them totally was later supported by like-minded governments that worked to enshrine this ban in international law.
Working together on the landmines issue, this coalition of NGOs and governments made a dramatic breakthrough - the convention banning anti-personnel landmines was negotiated, signed and ratified in just over 23 months.
