The Aztecs primarily shared their history from generation to generation through storytelling and oral traditions. They told stories of their past, which included myths, legends, and historical events. This oral tradition was vital for preserving their culture and identity.
Additionally, they employed pictorial writing, including hieroglyphs, to document historical events, rituals, and other important information. Although quipu was used by the Inca civilization, the Aztecs did not use it for record-keeping. They also carved images in stone, which could serve as memorials or record significant events and achievements.
In summary, the main methods the Aztecs used to share their history were oral storytelling, hieroglyphs, and stone carvings.
