again attacked Lubb's lands, laying siege to Grañón, but was forced to lift the siege when Lubb moved with an army toward Alava. This threat neutralized, Lubb turned toward Pallars, ravaging the lands, killing hundreds and taking a thousand captives, including Isarn, Count Raymond's son, who was kept in Tudela for a decade before being freed. In 905, a coalition of the King of Asturias, the counts of Aragon and Pallars, and, it is sometimes claimed, Lubb ibn Muhammad, engineered a coup in Navarre that brought Sancho Garcés to the throne in place of Fortún Garcés. Two years later, Lubb launched an attack on Pamplona and fought at "Liédena" on 30 September 907, resulting in a total rout of the Banu Qasi forces, while Lubb was killed. The transcendent battle marked a permanent change in the regional balance, Sancho's Pamplona becoming a major regional power, while it initiated the final decline of the Banu Qasi. Decline (905-929) With the fall of Lubb, his local rivals immediately fell upon the Banu Qasi lands. Sancho descended toward Calahorra. The Tujibids finally broke the siege of Zaragoza and captured Ejea. Al-Tawil retook the lands he had lost, and proceeded to overrun the family's eastern enclave, taking Barbastro and Lleida. Monzon was briefly controlled by Lubb's brother Yunus ibn Muhammad, but he could not hold it, and Monzon too fell to the al-Tawil. In the reduced western lands, Lubb was succeeded by brother Abd Allah ibn Muhammad al-Qasawi. In 911, Abd Allah and al-Tawil jointly, along with al-Tawil's brother-in-law Galindo Aznárez II of Aragon, attacked Pamplona. After destroying several castles, they developed cold feet and withdrew, but were caught by Sancho. Al-Tawil defected and escaped, while Galindo was crushed and forced to recognize Sancho as feudal sovereign, ending the autonomy of the Aragon. Arab sources describe Abd Allah's rear-guard action at Luesia as a victory, but if so it was only a tactical victory and he immediately retreated south. In 914, Sancho turned the tables, marching into the heart of the Banu Qasi homeland, taking Arnedo and attacking Calahorra. In the next year, 915, Sancho turned toward Tudela, and there captured Abd Allah, killing a thousand of his best men. Mutarrif ibn Muhammad al-Qasawi, Abd Allah's brother, rushed to relieve the city, and Abd Allah was ransomed, his daughter Urraca and probably son Furtun ibn Abd Allah being given as hostages.
