From the 12th century to the Reformation in 1536 its name was simply the Chancellery (Danish: Kancelli). The chancellor was appointed by the king from among bishops. It had the responsibility of the expedition of letters and orders from the king. Later it also gained the responsibility of copying and archiving the king's regulations.
After the Reformation the Chancellery was renamed Danish Chancellery (Danish: Danske Kancelli) to distinguish it from the German Chancellery (Danish: Tyske Kancelli). The Danish Chancellery was responsible for all correspondence in Danish and the civil administration of Denmark, Norway and Sweden. The German Chancellery had similar responsibility for the German and Latin correspondence and the civil administration of duchies of Schleswig and Holstein. Before, 1770, when it was separated into its own ministry, the German Chancellery was also responsible for foreign policy towards all but the Nordic countries.
The chancellor was now a noble and not a clergyman.
Over the years the chancellery gained a strong governmental power in additional to its administrative responsibilities.
First mentioned in 1550s Rentekammeret (lit. Rent Chamber) was a part of the Danish Chancellery. It had the responsibility of the state financial administration. Under and after Christian IV the central administration grew rapidly. Bureaus such as a postal service and customs where created.
