Since the publication of the first issue in 1883, De Nederlandsche Leeuw is the leading Dutch magazine in the field of sex and heraldry. The genealogical, heraldic and cultural-historical articles are based on thorough and thorough research. They offer no dry enumeration of dates and family names, facts and personal data are placed in a broader perspective. There is a lot of attention for socio-economic, demographic and geographical aspects and for the portrait iconography. The journal also contains a question and answer section in which data can be exchanged. De Nederlandsche Leeuw is an indispensable tool for anyone who deals with family history in a scientifically responsible way and contains a wealth of data for (art) historians and archivists.
