Kanauj is of high antiquity and renown. Founded long before the dawn of the
Christian era, it first rose to importance in the sixth century a.d. when
it became the capital of the Maukharis and when it grew rapidly in
authority and influence till its conflict with later Guptas. This followed
Harsa of Thaneswar assuming control of affairs in Kanauj. Harsa's death
plunged Kanauj into anarchy and darkness that lasted for about half a
century. However, as a result of the protracted campaigns of the next
rulers, Pratiharas, Kanauj grew to enormous dimensions camprising
territories as widely apart as Saurastra and North Bengal, Magadha and
Rajputana till it fell from its high position because of armed adventures
of Mahmud and then Sihabuddin Ghori. History of Kanauj presents, in short
the story of this ancient realm which is full of political vicissitudes and
ephemeral grandeur.
