The Zen Peacemakers is a diverse network of socially engaged Buddhists, currently including the formal structures of the Zen Peacemakers International, the Zen Peacemaker Order and the Zen Peacemaker Circles, many affiliated individuals and groups, and communities formed by Dharma Successors of Roshi Bernie Glassman. It was founded by Bernie Glassman and his second wife Sandra Jishu Holmes in 1996, as a means of continuing the work begun with the Greyston Foundation in 1980 of expanding Zen practice into larger spheres of influence such as social services, business and ecology but with a greater emphasis on peace work. Eve Marko, Bernie Glassman's third wife, is a founding teacher of the Zen Peacemaker Order. Zen Peacemakers have developed from the White Plum Asanga lineage of Taizan Maezumi.
