Emperor Harshavardhana, also known as Harsha, was a significant ruler in North India during the 7th century CE. He initially established his political center in Thanesar, which is located in the present-day state of Haryana.
Later in his reign, Harsha made a strategic decision to transfer his capital from Thanesar. The new capital city chosen for his expanding empire was Kannauj.
Kannauj, situated in the present-day state of Uttar Pradesh, offered several advantages. Its central location made it easier for Harsha to administer his vast territories effectively. The city was also a major political and cultural hub during that period, enhancing the prestige and reach of his empire.
The transfer of the capital from Thanesar to Kannauj was a key event in the political geography of early medieval India, consolidating Harsha's power and influence across a large part of the subcontinent.
