Around 500 CE, banana cultivation was introduced to East Africa, likely by Indonesian seafarers who settled in Madagascar and the East African coast. Asian banana varieties, particularly plantains (AAB genome) and East African Highland Bananas (AAA-EA genome), adapted to local climates and became staple crops. Bananas provided a year-round carbohydrate source that could be harvested continuously without seasonal replanting. The high-yield and disease-resistant nature of these crops contributed to population growth and the development of complex societies throughout the Great Lakes region.
