The Royal Library

The collections of the Royal Library date back to the 17th century when the founder of the Library, King Frederik III, acquired a number of private Danish libraries in the 1650's and 1660's. Up until c. 1800 the growth of the Library was primarily due to incorporation of private collections, either partly or in their entirety.

Amongst the most significant of these collections were the ducal library of Gottorp Castle which was conquered by Danish troops in 1713 and a few decades later was brought to Copenhagen, Count Otto Thott's large collections of incunabula and manuscripts which was given to the Royal Library as a bequest upon Thott's death in 1785, and Henrik Hielmstierne's collection of printed Danish books which was donated to the Library in 1807.
