In prison, Luxemburg deepened her analysis with the Junius Pamphlet of 1915. In this document she specifically rejects the notion of oppressor and oppressed states: "Imperialism is not the creation of one or any group of states. It is the product of a particular stage of ripeness in the world development of capital, an innately international condition, an indivisible whole, that is recognisable only in all its relations, and from which no nation can hold aloof at will."
