Ghiyasuddin Balban (1266-1287) claimed himself to be the ruler of vast empire. It stretched from Bengal (Gauda) in the east to Ghazni (Gajjana) in Afghanistan in the west. It included all of south India.
People from different regions- Gauda, Andhra, Kerala, Karnataka, Maharashtra and Gujarat fled before his armies came. Historians regard this as exaggerated claims. It is a question of debate why rulers kept claiming about their conquests.
