Ernest François Eugène Douwes Dekker also known as Setyabudi or Setiabudi (8 October 1879 – 28 August 1950) was an Indonesian-Dutch nationalist and politician of Indo descent. He was related to the famous Dutch anti-colonialism writer Multatuli, whose real name was Eduard Douwes Dekker ("Douwes Dekker" being their surname). In his youth, he fought in the Second Boer War in South Africa on the Boer side. His thoughts were highly influential in the early years of the Indonesian freedom movement.

After Indonesian independence, he adopted the Sundanese name Danoedirdja Setiaboedi.

Early years

Douwes Dekker was born in Pasuruan, in the north east of Java, 80 km south of Surabaya. His father was Auguste Henri Edouard Douwes Dekker, a broker and bank agent, of a Dutch family living in the then-Dutch East Indies. His Indo (Eurasian) mother was Louisa Margaretha Neumann, of half-German and half-Javanese descent. Douwes Dekker's great-uncle was the famous writer Eduard Douwes Dekker, author of Max Havelaar.

After studying in Lower School in Pasuruan, he moved to Surabaya, and later to Batavia. In 1897, he gained his diploma and worked on a coffee plantation in Malang, East Java. Later he moved to a sugar plantation in Kraksaan, East Java. During his years in these plantations, he came in contact with ordinary Javanese and saw the realities of their hard work.

Second Boer War

In 1900, along with his brothers Julius and Guido, he decided to volunteer for service in the Second Boer War. They arrived in Transvaal, and became citizens of that state. He based his actions on the belief that the Boers were victims of British expansionism, and as a fellow descendant of the Dutch, he was obliged to help. In the course of the war, he was captured by the British and placed in an internment camp on Ceylon.

Dekker was later released and returned to the Dutch East Indies via Paris in 1903.

Indonesian struggle

In the Dutch East Indies, Dekker, then still in his twenties, started a career as a journalist, first in Semarang and later in Batavia. There he worked with Indo activist Karel Zaalberg, the chief editor of the newspaper Bataviaasch Nieuwsblad, whom he befriended. On 5 May 1903, he married Clara Charlotte Deije, who would bear him three children. Unlike other people of European descent, he did not favour colonialism, strongly advocating self-management, and finally the independence, of the Dutch East Indies. This was prompted partly by his experience in watching the lives of plantation workers and partly by the discrimination he had suffered, through being only considered half-Dutch and a second-class citizen.

During these times, he published many articles advocating independence, and "Indies nationalism." In 1913, close associates of Douwes Dekker, including physicians Tjipto Mangunkusumo and Suwardi Surjaningrat, established the Native Committee in Bandung, which later became the Indische Partij. This was considered a breakthrough because most organisations had never so openly advocated independence. In March 1913, the party claimed approximately 7000 members, approximately 5500 of whom were Indos (people of mixed Dutch-Indonesian ancestry) along with 1500 native Indonesians. The Colonial government quickly became worried, and the party was forbidden. This led to the exile to the Netherlands of Douwes Dekker and his two Javanese associates.

In exile, they worked with liberal Dutchmen and compatriot students. It is believed that the term Indonesia was first used in the name of an organization, the Indonesian Alliance of Students, with which they were associated during the early 1920s. After his party was forbidden it directly inspired the foundation of the Insulinde and an Indo-European party named 'Indo Europeesch Verbond' chaired by his friend Karel Zaalberg and also advocated independence. Many of the former 'Indische Partij' members joined the new party that grew to 10.000 members.

In 1918 he was allowed to return to the East Indies and was responsible for reforming the 'Insulinde' into the new 'National Indische Party' (NIP). Together with his new associate P.F. Dahler and old companion Tjipto Mangoenkoesoemo, he became a prominent leader of the NIP. After the NIP was involved in the Surakarta farmers' strike, he was imprisoned again by the colonial authorities in 1921.

After his release from prison in 1922, he taught in Bandung in a lower school. Two years later, as head of the school, he renamed it the "Ksatrian Institute." The government officially recognised this institute in 1926. In the same year, he married Johanna Mussel, one of its teachers, six years after divorcing his first wife. Sukarno was a teacher at one of his schools.
