What subjects did Karl Marx write about for the New York Tribune?

Between 1851 and 1862, Karl Marx served as a European correspondent for the New York Tribune, contributing nearly 500 articles and editorials to the newspaper.1

In his role as a correspondent, Marx analyzed a wide range of social movements and political agitations across the globe, covering events and developments in regions spanning from India and China to Britain and Spain.1

It is important to note that while these articles were published under Marx's name, his collaborator Friedrich Engels authored approximately one-fourth of them. Engels specifically focused on topics such as nationality questions, military matters, and international affairs. Additionally, a series of articles written by Engels during 1851–1852 under Marx's name were later published as Revolution and Counter-Revolution in Germany in 1848.12
