The Einstein Observatory's and the IUE's contributions to knowledge of coronal formation in late-type stars are discussed. The HR diagram of stars seen as X-ray sources by these observatories is presented, and the influence of rotation on X-ray emission is reviewed. Emission from the Alpha Cen system and from active stars with quiescent coronae is examined, and the extent of the contribution of emission from normal stars to the soft X-ray background is addressed. The quiescent and flare emission from Alpha Cen, the temporal variability of X-ray emission from a sample of active chromosphere stars, and the predicted contribution of chromospheric emission to the diffuse soft X-ray background are depicted. Chromospheric indicators of activity are discussed, the connection between surface magnetic fields and X-ray emission in the chromosphere is briefly reviewed, and the quantitative links between X-ray data and magnetic fields is summarily presented.
