Height is usually selected in favor of protein, strength, climate, … and war.

Genetic Factors:
Founder Effects: Northern European populations could have experienced founder effects that emphasized genes for greater height and a more robust physique.
Positive Selection: These genetic traits may have offered survival advantages in the environments where these populations evolved, thereby becoming more common over generations.
Climate: The cold climate may have led to a selection pressure favoring a body type that conserves heat more efficiently. Larger, sturdier bodies have a lower surface area-to-volume ratio, which aids in heat conservation.
Diet: A diet rich in protein and dairy, facilitated by agriculture and animal husbandry, can lead to greater height and robustness.
Sexual Selection: Cultural preferences could favor taller, sturdier builds. Over time, this would result in a population that is taller on average.
Social Stratification: In some societies, height and build could be associated with social standing, potentially leading to better opportunity for nutrition and mating for taller individuals, which could be passed on to offspring.
