The Gupta Empire ruled northern India between 320-600 CE. It was a time of political stability and economic prosperity, considered a golden age of Hindu culture. The empire expanded under rulers like Samudragupta and Chandragupta II to control most of the subcontinent. Architecture flourished with the construction of ornate Hindu temples in brick and stone. Sculpture and paintings at sites like Ajanta depicted scenes from Hindu epics and myths. Scholars like Aryabhata and Kalidasa also thrived during this period of learning and cultural achievements.
