For five hundred years, Latinx peoples across political borders have struggled for independence, peace, justice, democracy, and for Mother Earth. Revolutionary change in the U.S. and beyond will require a strong Latinx left, organizing for racial, language, national, and cultural justice within the U.S., and in support of and in conjunction with a renewed left in Latin American countries. Latinx people will comprise one third of the U.S. population within a generation; winning the next generation to socialism is an imperative. In order to contribute to the building of a strong, united, continental Latinx left, we offer perspectives and analysis from a range of U.S. and Latin American leftists.
