About Us

The ISO has branches across the country. Our members are involved in helping to build a number of struggles: the movement to stop the war on Iraq and Afghanistan; fights against racism, police brutality, and anti-immigrant scapegoating; the struggle for women's rights, like the right to choose abortion; opposing anti-gay bigotry; and standing up for workers' rights. We are committed to building a left alternative to a world of war, racism, and poverty. Read more on where we stand (brief version / longer version).

Read reports from struggles taking place around the country — and socialist analysis of world events — in our daily online newspaper, Socialist Worker.

Get in-depth Marxist analysis, history and coverage of discussion and debates on the left from the bimonthly magazine, the International Socialist Review.

We believe that activists need to take ideas, history, and politics into the many struggles for social justice today. Learning the lessons of past victories as well as defeats can arm a new generation of fighters for a better world. Take a look at some of the books available through Haymarket Books.

Each summer, the ISO helps sponsor Socialism, a national conference where socialists and activists from around the country — and around the world — come to debate and discuss politics and strategize about the important struggles of the day. Check out some of the talks from the last Socialism Conference.

There are many more resources on our national ISO website as well. If you’d like to get involved or check us out, come to a meeting or contact us at
