We trace the evolution of research on extreme solar and solar-terrestrial events from the 1859 Carrington event to the rapid development of the last twenty years. Our focus is on the largest observed/inferred/theoretical cases of sunspot groups, flares on the Sun and Sun-like stars, coronal mass ejections, solar proton events, and geomagnetic storms. The reviewed studies are based on modern observations, historical or long-term data including the auroral and cosmogenic radionuclide record, and Kepler observations of Sun-like stars. We compile a table of 100- and 1000-year events based on occurrence frequency distributions for the space weather phenomena listed above. Questions considered include the Sun-like nature of superflare stars and the existence of impactful but unpredictable solar ”black swans” and extreme ”dragon king” solar phenomena that can involve different physics from that operating in events which are merely large.

E.W.C. and I.U. benefited from participation in the Institute for Space-Earth Environmental Research (ISEE) workshop on Extreme Solar Events organized by Fusa Miyake and Ilya Usoskin held at Nagoya University from 02–06 October 2018, and from membership on the International Space Science Institute (ISSI) International Teams led by Athanasios Papaioannou on high-energy solar particle events. E.W.C. thanks Nat Gopalswamy, Hisashi Hayakawa, Hugh Hudson, Eduard Kontar, Jeffrey Love, Florian Mekhaldi, Raimund Muscheler, Kosuke Namekata, Yuta Notsu, Dean Pesnell, Art Richmond, and Astrid Veronig for helpful discussions, and Lyndsay Fletcher for sponsoring his stay in Glasgow. C.J.S. is grateful for the support of the National Solar Observatory for the completion of this project. K.S. was supported by JSPS KAKENHI Grant Number 21H01131 and thanks Y. Notsu, K. Namekata, H. Maehara, D. Nogami, S. Okamoto, H. Hayakawa for helpful discussions. I.U. benefited from membership on the ISSI International Team led by Fusa Miyake and himself on extreme solar events and acknowledges support from the academy of Finland (project No. 321882 ESPERA). We thank Owen Giersch and Gelu Nita for kindly sharing data, Astrid Veronig for assistance with Fig. 16, and Peter Gallagher and Brian Dennis for providing Fig. 32. We acknowledge constructive comments from the assigned editor and two reviewers which significantly improved the paper.
