History of India:

The Hindu Shahis under Jayapala, is known for his struggles in defending his kingdom against the Ghaznavids in the modern-day eastern Afghanistan and Pakistan region. Jayapala saw a danger in the consolidation of the Ghaznavids and invaded their capital city of Ghazni both in the reign of Sebuktigin and in that of his son Mahmud, which initiated the Muslim Ghaznavid and Hindu Shahi struggles. Sebuk Tigin, however, defeated him, and he was forced to pay an indemnity. Jayapala defaulted on the payment and took to the battlefield once more. Jayapala however, lost control of the entire region between the Kabul Valley and Indus River.
