From the website:
The Foundation’s mission is to carry on the vision of its founder, Samuel Rubin, whose life was dedicated to the pursuit of peace and justice and the search for an equitable reallocation of the world’s resources. The Foundation believes that these objectives can be achieved only through the fullest implementation of social, economic, political, civil and cultural rights for all the world’s people.
The foundation has an open application process because we are interested in learning about organizations we are not familiar with that are working for peace, social justice, and human rights.
There are no geographic limitations, however organizations based outside the United States must be sponsored by a U.S.-based organization with tax-exempt status. The majority of grants are $5,000.
