The National Reserve Corps (Dutch: Korps Nationale Reserve, abbreviated Natres) is a part of the Royal Netherlands Army.^[1] NATRES is a corps in the sense that it has a specialized task. The reservist is part of the military, just like all Dutch military personnel, but mostly working parttime or sometimes full time as a replacement for regulars.

Since the 13th century, the Dutch government has relied on voluntary armed citizens to defend their homes and to maintain public order. At first this task was carried out by so-called 'shooter guilds'. In the 16th century the voluntary armed citizens, under the influence of William I, Prince of Orange, were organised into militias. These militias were dissolved in 1908.

The outbreak of the First World War and the growing foreign threat lead to the formation of a new unit called the 'Voluntary Landstorm' on the 4 August 1914. At the end of World War I this unit consisted of 6,000 men. In the turbulent times of the Interbellum the Dutch Prime Minister Hendrikus Colijn made the decision to extend the service of this force. At the beginning of World War II this unit consisted of around 98,000 men.

In the years after World War II again the need was felt for a rapidly deployable unit for the defense and security of Dutch territory. While the majority of the Dutch forces then were deployed in Indonesia, the threat of the Soviet Union increased. Therefore, the National Reserve was established on the 14 April 1948. During the Cold War the National Reserve developed into a versatile part of the Royal Dutch Army and received the status of Corps. In the 80s the first women entered the National Reserve Corps. After the Cold War, the Royal Dutch Army changed dramatically in character. Conscription for military service was suspended. The Dutch Army shrank and became more frequently involved in peacekeeping or peace-enforcing missions abroad which resulted in a renewed relevance of the corps.
