Background Muslim and Christian sources quote that while Musa bin Nusayr was eager to cross the
Straits of Gibraltar to Hispania, he determined to do so only when a Visigoth nobleman,
Julian, Count of Ceuta, had encouraged him to invade Iberia, telling him of the people's sufferings and the injustice of their king,
Roderic, while giving him cause for conquest by telling him of the riches that would be found, and of the many palaces, gardens and beauties of Hispania. Legend tells that Julian wished for the fall of the Visigothic kingdom because his daughter,
Florinda la Cava, had been raped by Roderic.
Invasion named after Musa bin Nusayr After ordering a successful reconnaissance raid with 400 soldiers on the Spanish coast at
Tarifa where the raiding force returned with a booty captured without any reported resistance, Musa decided to launch a larger invasion force, ordering his lieutenant
Tariq bin Ziyad to cross the strait with approximately 7,000 Berbers and Arabs, and landed at
Gibraltar (from Jebel Tariq, meaning Tariq's mountain in Arabic). The expedition's purpose must have been to conduct further raids and explore the territory. Tariq's army contained some guides supplied by Julian. Three weeks after his landing, the Muslims were faced with a superior Visigoth royal army of 100,000 troops under Roderic. The Muslims won the
Battle of Guadalete, and the entire Visigoth nobility was all but exterminated at the battle. The Muslims then marched towards Córdoba, bypassing several strong fortifications. The well-defended city fell, and Tariq established a garrison there consisting mainly of the city's Jews who welcomed the invaders, having been subjected to conversion from the Visigoths for centuries. Tariq then continued on his way to
Toledo. Musa, learning of Tariq's successes, landed in Iberia with an army of 18,000 Arabs and Berbers. He planned to rendezvous with Tariq at Toledo, but first proceeded to take
Seville, which Tariq had bypassed, and where Musa met stiff resistance, and succeeded after three months of siege. He then campaigned in the province of
Lusitania, eliminating the remaining Gothic resistance there. His last destination before meeting Tariq was to subdue
Mérida, capital of Lusitania. After five months of siege and inconclusive fighting, a group of
Ceutans pretended to be Christian reinforcements and managed to convince the guards into opening the gates. Once inside, the "reinforcements", nearly 700, overwhelmed the guards and managed to keep the gates open for the Muslims to enter the city and capture it. After Mérida, Musa divided his forces, taking the majority with him to meet Tariq at Toledo where he would remain for winter. The remainder of his forces were led by his son '
Abd al-Aziz, who would return to Seville to deal with an uprising. 'Abd al-Aziz made short work of the rebellion. He then conducted several campaigns on the return journey in the territories of Lusitania.
Coimbra and
Santarém were captured in the spring of 714. 'Abd al-Aziz then campaigned in
Murcia. The Duke of Murcia,
Theodemir, or Tudmir as he was called by the Muslims, surrendered to 'Abd al-Aziz after several hard-fought engagements in April 713. The terms imposed on Theodemir declared that the duke would keep the citadel of
Orihuela and several other settlements, including
Alicante and
Lorca on the Mediterranean, that his followers will not be killed, taken prisoner, forced into Islam, and that their churches will not be burned. It also demanded that Theodemir not encourage or support others to resist the Muslims, and that he and every citizen of his dominion pay an annual tax in money and other goods. Musa finally met up with Tariq where there was an argument over the latter's booty, which reportedly included a gold table covered with gems and other precious stones that had reputedly once belonged to
Solomon. Meanwhile, Musa's messenger,
Mughith al-Rumi (the Roman) who had been sent to Caliph
al-Walid I to inform him of the situation in Hispania, had returned. The Caliph requested Musa to withdraw and to report in person to
Damascus. Musa chose to ignore this order temporarily, knowing that if he did not continue his advance, Visigoth resistance may increase and turn the tables against the Muslims. Having done so, he continued with Tariq to the north; Musa heading for
Zaragoza, to which he lay siege, while Tariq continued to the provinces of
León and Castile, capturing the towns of
León and
Astorga. Musa continued after taking Zaragoza to the north, taking
Oviedo and reaching as far as the
Bay of Biscay. The Islamic conquest of Iberia now complete, Musa proceeded to place governors and prefects throughout the newly conquered
Al-Andalus, before returning to Damascus with most of the booty captured from the Jihad. ==Return to Damascus==
