The Historical Attractor Theory (HAT) describes physical reality in terms of complete histories governed by a universal historical functional. Within this framework, physically realized configurations correspond to stable historical attractors, while effective dynamics emerge through projection. In this work, we apply HAT to the electroweak sector and show that electroweak mixing arises as a consequence of historical closure. Interpreting the Higgs field as a closure mode, we demonstrate that integrating out this stabilized degree of freedom induces an effective mixing between gauge channels at the level of the historical functional. The electroweak mixing angle is then fixed by a global variational principle, rather than introduced as a fundamental parameter. We further show that the resulting value is controlled by a single dimensionless quantity determined by the structure of the historical attractor and is stabilized by a historical renormalization-group flow. These results indicate that the electroweak mixing angle and the electric charge emerge as consequences of global historical stability within a universal framework.
