Raden Mas Tirto Adhi Soerjo founded Medan Prijaji in Bandung, widely regarded as a pioneering indigenous-owned Malay-language newspaper that helped shape early nationalist public discourse in the Dutch East Indies.
The newspaper Djawi-Hisworo began printing in Surakarta in Malay and Javanese, and became associated with the early Boedi Oetomo milieu—illustrating the growth of indigenous-language journalism within late-colonial political and cultural networks.
Pewarta Deli began publication in Medan as a Malay-language newspaper. It later gained prominence for criticism of colonial society and plantation abuses, and for giving space to nationalist and reformist currents—making it part of the expanding indigenous press sphere outside Java.
Soewardi Soerjaningrat (later Ki Hadjar Dewantara) circulated the polemical text “Als ik eens Nederlander was” (“If I were a Dutchman”) in the context of protests against the Dutch centennial celebrations, exemplifying how print and pamphleteering became flashpoints for colonial repression.
E. F. E. Douwes Dekker, Tjipto Mangunkusumo, and Soewardi Soerjaningrat were exiled from the colony (rather than prosecuted under a specific press law), using the Governor-General’s broad “exorbitant rights” authority—an emblematic use of administrative power against nationalist propaganda and press activity.
Journalist Mas Marco Kartodikromo came under investigation and was convicted after publishing anti-colonial editorials; his sentencing reflected the late-colonial pattern of using persdelict (press offenses) to criminalize political journalism and intimidate editors.
The Malay-language newspaper Neratja began publication in Weltevreden (Batavia). Though initially aligned with Ethical Policy-era ideas, it became tied to Sarekat Islam figures and later faced pressure under colonial press controls—showing the contested space between “loyal” and oppositional indigenous journalism.
Editorial control of Sinar Djawa (later Sinar Hindia) shifted toward the Sarekat Islam left, with figures such as Semaun and Mas Marco playing major roles. The paper’s evolution highlights how newspapers became central instruments for mass politics and targets for colonial surveillance.
Ki Hadjar Dewantara founded the Taman Siswa school system in Java. While primarily educational, it also built a nationalist public sphere around indigenous culture and self-determination, provoking official suspicion in a period when print, schools, and associations were closely policed.
PKI figure Aliarcham was arrested in late 1925 and later confined at Boven-Digoel, where he died. His case illustrates how strikes, political organizing, and associated print networks were treated as security threats in the late colonial order.
Mas Marco Kartodikromo was exiled to Boven-Digoel following his involvement in the 1926 revolt and his broader political-journalistic activity, underscoring how press activism and “subversion” charges could culminate in administrative exile.
The Dutch colonial government opened the Boven-Digoel internment camp in remote New Guinea as a site to confine political detainees (notably communists and other perceived subversives), institutionalizing exile and detention as tools alongside censorship and prosecution.
Dutch authorities arrested Sukarno and other Indonesian National Party (PNI) leaders, leading to a major political trial in Bandung. The case became a focal point for press coverage and state control over nationalist messaging.
During the Bandung Landraad proceedings, Sukarno delivered his defense speech Indonesia Menggugat (“Indonesia Accuses”), turning the courtroom into a platform for anti-colonial argumentation and intensifying the colonial state’s concern with press amplification of nationalist ideas.
The Governor-General issued the Press Curbing Ordinance (Staatsblad 1931 No. 394), empowering authorities to prohibit printing/publishing/distribution of “undesirable” periodicals—marking a significant escalation from prosecuting individuals to administratively suppressing publications.
The newspaper Pemandangan began publication in Batavia in 1933. Its later experiences with censorship demonstrate the tightening constraints on Indonesian-language public debate in the 1930s, especially under the post-1931 regulatory environment.
Dutch authorities arrested leaders connected to the New PNI movement, including Mohammad Hatta and Sutan Sjahrir, reflecting intensified repression of nationalist leadership (and their networks of writing and public communication) in the mid-1930s.
Colonial officials decided to exile Hatta and Sjahrir in early 1935, initially to Boven-Digoel (with later relocation noted in some accounts). Exile functioned as an administrative complement to censorship and political trials, removing prominent communicators from the public sphere.
