Aparajita Varman vs Sancho II of Castile

Aparajita Varman formed an alliance with the Western Ganga dynasty to counter the growing power of the Cholas. This alliance provided temporary military support but ultimately failed to prevent the Chola conquest of Pallava lands.

Aparajita Varman lost the Pallava capital Kanchipuram to the Chola king Aditya I after a series of military campaigns. This loss marked the final decline of Pallava power and the transfer of hegemony in the Tamil region to the Cholas.

Aparajita Varman was defeated and killed by the Chola king Aditya I at the Battle of Tirupati. This defeat ended the Pallava dynasty's rule, as Aditya I annexed the Pallava territories into the expanding Chola kingdom.

Sancho II conquered the Kingdom of Leon from his brother Alfonso VI, following the division of their father Ferdinand I's realm. He defeated Alfonso at the Battle of Llantada and forced him into exile in Toledo. This conquest united Leon and Castile under Sancho's rule.

Sancho II conquered the Kingdom of Galicia from his brother Garcia II, who was captured and imprisoned. This conquest completed Sancho's unification of the realms of his father, making him the most powerful Christian ruler in Iberia.

Sancho II besieged the city of Zamora, held by his sister Urraca, who had rebelled against him. During the siege, Sancho was assassinated by a Zamoran noble named Vellido Dolfos. His death ended his unification efforts and allowed his brother Alfonso VI to reclaim the throne.
