Hendrikus (Hendrik) Colijn (22 June 1869 – 18 September 1944) was a successful Dutch soldier, businessman and politician. In 1922 he accepted the political leadership of the Anti Revolutionary Party (Calvinist) from Dr. Abraham Kuyper. Between 1925-1926 and 1933-1939 he served five times as Prime Minister. During the 1930s his government faced the effects of the Great Depression, which took a heavy toll on the Netherlands. Colijn's government responded to the economic crisis with a very strict fiscal policy, which may have further weakened the Dutch economy. Colijn's decision to adhere to the Gold Standard until 1937, long after most of the trading partners of the Netherlands had dropped it, also played a role in lengthening the economic crisis. In 1939, his latest cabinet, with Protestant and liberal ministers but without catholic ministers, served only three days before a government crisis. From 1927-1929 he also was head of the Dutch delegation to the League of Nations in Geneva.

The Germans tried to have him confess that he had conspired with the British to invade the Netherlands to serve as an excuse for the Germans invasion. Late in the war after the tide had turned against the Germans, Himmler wanted to keep Colijn available as a possible intermediary with the British as he had done earlier for the Kaiser. In March 1943 he was put under house arrest in a remote mountain hotel in Ilmenau (Thuringen), Germany, where he died on September 18, 1944. On 06 October 2006, in a solemn act, before the hotel building a Monument was revealed in honours of the H.Colijn.
