Mas Marco Kartodikromo (Cepu, Java, 1890 – Boven Digul, Indonesia, 1932) was a prominent writer and activist in the early days of the nationalist movement in the Dutch East Indies. Born and raised in a colonial environment, he presented himself as the mouthpiece of the common Javanese, loudly and emphatically inviting readers of every nation and race, including Dutch administrators, to engage in discussions about inequalities and injustices on the island of Java, caught in the process of colonial modernisation. He was the editor of various short-lived newspapers in central Java; working with the slogan sama rata sama rasa (‘equal standards, equal emotions’), his writings and speeches challenged the competence of the colonial authorities as well as the sagacity of the Javanese aristocracy.
