Step-by-step explanation:
The gods and goddesses took sides for the Greeks or Trojans in Greek mythology due to the merging of two different peoples that became the Greeks. The indigenous peoples of the land now called Greece had matriarchal beliefs and pacific tendencies, while the Aryan invaders had patriarchal beliefs and were belligerent. The tales of the deities in Greek mythology were an amalgamation of the tales and divinities of these two peoples to accommodate their different belief systems. For example, Zeus, the king of gods, had a wife Hera who represented the highest female deity of the indigenous peoples.
