Intermediate mass black holes (IMBHs) are an (as yet) elusive class of black holes that are expected to lie in the $10^2-10^5\,M_{\odot}$ range, between the firmly established stellar mass black holes and ${\gtrsim}10^6\,M_{\odot}$ super-massive black holes. Predicted by a variety of theoretical models IMBHs are the potential seeds of super-massive black holes and are expected to power some of the brightest extra-nuclear X-ray sources. This brief review is the result of a presentation and subsequent discussion of IMBHs that took place during the 12th International Frascati workshop on “Multifrequency Behaviour of High Energy Cosmic Sources”. The manuscript aims to provide a concise and up-to-date review of the different evolutionary scenarios for the creation of IMBHs. Throughout the text I emphasize the importance of the identification and classification of IMBSs in our effort to understand the formation of supermassive black holes and their co-evolution with their host galaxies.
