The Standard Model of particle physics was developed throughout the mid-20th century, with significant contributions occurring from the 1950s to the 1970s. Key milestones include the establishment of quantum electrodynamics (QED) in the 1940s and the unification of the weak and electromagnetic forces in the 1970s, which led to the complete framework of the Standard Model. It was effectively finalized with the discovery of the Higgs boson in 2012, solidifying its predictions about particle interactions.
