The Madison Arcatao Sister City Project as part of the U.S.- El Salvador Sister Cities (USESSC) network works forsocial change by building and defending sustainable communities andeconomies based on solidarity, dignity, self-determination. Our work isdriven by mutual community accompaniment, organizing, education,
advocacy and fundraising.


MASCP is a not-for-profit volunteer organization established in 1986 when Madison’s Common Council named Arcatao it’s first official sister city. MASCP has a core group of 10-15 members who provide basic leadership for the organization. There is a community of 150+ Friends of MASCP who participate financially and on an as-needed basis as the group’s activities require. Through the work of MASCP the people in Madison and Arcatao nurture friendships that energize them to work for social and economic justice at home and beyond the boundaries of their own countries.


MASCP also contributes to the organizing work of US El Salvador Sister Cities (USESSC)–a nation-wide organization that joins all 17 US El Salvador sister cities in efforts for friendship, understanding and positive change both north and south.


The U.S.-El Salvador Sister Cities Network is a grass-roots network of U.S. citizens and residents who have formed ongoing partnerships with rural communities in El Salvador through The Association of Rural Communities for Development in El Salvador (CRIPDES). Our sistering began in 1986 in response to US intervention in El Salvador’s Civil War (1980-1992) and continues today to form grass-root coalitions to work for structural change in the US and in El Salvador.


Our network is formed by these U.S. Committees working in solidarity with their organized Sister Communities in El Salvador as well as by Three National Working Groups: Migration, Environment and Climate Change, Historical Memory and U.S. Intervention.


We use the following strategies in our work for social change:

1. Strengthen community relationships

2. Education, awareness raising and outreach

3. Advocacy

4. Work in coalition as part of larger social movements

5. Share economic and human resources
