Question

The key element in the expansion of the Indo-Europeans from their homeland was: iron weapons, monotheism, horses, or trade. I said it was iron weapons am I correct?

Answer 1

The key element in the expansion of the Indo-Europeans from their homeland was actually **horses**. While iron weapons contributed to military prowess in later periods, the ability to domesticate and use horses for both transportation and warfare significantly facilitated the migration and expansion of Indo-European groups. Horses allowed for greater mobility, enabling these groups to cover larger distances and establish control over vast territories.
