How development took place within the Northern International movement of the 15th century?

The Northern International movement of the 15th century, primarily characterized by the artistic and intellectual advancements in regions like the Low Countries and Germany, was marked by a convergence of burgeoning Humanism and detailed realism in art. Artists such as Jan van Eyck and Albrecht Dürer emphasized meticulous attention to naturalism, perspective, and emotion, reflecting both a deepening of observational techniques and the influence of Italian Renaissance ideals. This period also saw the proliferation of printmaking, which facilitated the spread of ideas and styles across Europe. Ultimately, the movement laid the groundwork for the Northern Renaissance, intertwining art, culture, and early modern thought.
