The Higgs boson is the long sought missing piece of the Standard Model of Particle Physics. After reviewing the theory and history of Higgs Boson and its previous search, I will report the latest important results from the CMS and ATLAS experiments at the LHC, i.e. a 125GeV boson has been discovered at 5 sigma confidence level. The new historical stage of Particle Physics has arrived to measure the properties of this Higgs like particle!
