Hendrikus "Hendrik" Colijn (22 June 1869 – 18 September 1944) was a Dutch politician of the Anti-Revolutionary Party (ARP; now defunct and merged into the Christian Democratic Appeal or CDA). He served as Prime Minister of the Netherlands from 4 August 1925 until 8 March 1926, and from 26 May 1933 until 10 August 1939. Early life He was born on 22 June 1869 in the Haarlemmermeer to Antonie Colijn and Anna Verkuijl, who had migrated to the newly-created Haarlemmermeer polder from the Land of Heusden and Altena for religious reasons. He was the first of six children, all of whom were born in Haarlemmermeer. Colijn grew up in the Land of Altena. Military service At the age of 16, he went to a military academy in Kampen for officer training, where he graduated as a second lieutenant in 1892. On 18 September 1893, he married Helena Groenenberg (23 September 1867 – 14 February 1947) and was sent to the Dutch East Indies. During his 16 years in the Dutch East Indies, he spent ten years in the colonial army. He served in the Aceh War as the lieutenant of J. B. van Heutsz and six further years in the colonial administration as a lieutenant when van Heutsz became Governor General in 1904. Colijn's letters to his wife from his period on Lombok reveal that his participation in acts of brutality which by modern standards would be considered severe war crimes: I have seen a mother carrying a child of about 6 months old on her left arm, with a long lance in her right hand, who was running in our direction. One of our bullets killed the mother as well as the child. From now on we couldn't give any mercy, it was over. I did give orders to gather a group of 9 women and 3 children who asked for mercy and they were shot all together. It was not a pleasant job, but something else was impossible. Our soldiers tacked them with pleasure with their bayonets. It was horrible. I will stop reporting now. Early political career After his return to the Netherlands in 1909, he was elected as an Anti-Revolutionary Party Member of Parliament for the district of Sneek (before 1918, the Dutch voting system was the same as the British). In 1911, he was appointed Minister of War and revised the Dutch Selective Service System.
