The Higgs boson was discovered in 2012 by the ATLAS and CMS experiments at the world’s most powerful particle collider, the Large Hadron Collider (LHC) in Geneva, Switzerland. This particle plays a unique role in fundamental physics. It gives all of the known elementary particles, including itself, their masses. While we now have a strong evidence that the Higgs field is indeed the unique source of mass for the known elementary particles, the next step is to search for new interactions that could also explain why the Higgs field has the properties required by the Standard Model of particle physics. The LHC has been central to this effort, turning the Higgs boson from a discovery into a precision tool through increasingly accurate measurements of its couplings, production, and decay modes. In this talk we present recent Higgs results from the LHC and discuss what they reveal about the Standard Model and possible new physics. Looking ahead, a next-generation e+e- collider would extend this program with per-cent-level precision measurements of Higgs properties not accessible at the LHC. The complementarity between the LHC and future colliders will be key to understanding the Higgs boson at a fundamental level.
