We will review the relevance of historical observations for current astrophysical problems, in particular for the  reconstruction of solar activity in the 17th century Maunder Minimium and the pre-telescopic time - as well as the study of historical supernovae in our Galaxy. Among other observations, we will discuss the strong 14-C variation around AD 775 detected in trees around the world and discuss possible causes like a nearby supernova,  a Galactic gamma-ray burst, a solar super-flare, etc.
