• Narrow-Line Seyfert 1 galaxies are an important class of Seyfert 1 galaxies. X-ray observations with ROSAT, XMM-Newton and Chandra have revealed many interesting and unexpected properties, e. g. steep soft (0.1-2.4) keV and hard (2-10) keV X-ray continua, a strong soft X-ray excess in many of these objects and unusually rapid and extreme X-ray variability. These X-ray properties are related to many optical and UV properties, such as the strength of the Fe II multiplet emission or the strength of the [OIII] emission. The unique combination of extreme observational properties in Narrow-Line Seyfert 1 galaxies allows for a more general understanding of the Seyfert phenomenon. This paper reviews the observational and theoretical progress made until October 2003.
