Marx and Engels wrote - The German Ideology. (A response to Feuerbach's materialism, laying out the ground work for the materialistic conception of history.
Broke from Left Hegelian idealism with a critique against Bruno Bauer and Max Stirner, leading to one of Marx's most famous quotes:

"The philosophers have only interpreted the world in various ways; the point is to change it."

Following the downfall of the Paris Commune (1871) – of which Marx gave a clear-cut materialistic analysis of these events in The Civil War In France, 1871 – and the Bakunin cleavage in the International), the organization was moved to U.S.

Marx's health became undermined, it was never very good in his later years.
He continued work to complete Capital, collected a mass of new material and studied a number of languages (Russian, for instance; Marx was fully fluent in German, French, and English)
