Conquest and Treaty According to the later chronicler
Ibn Abd al-Hakam, the
Tangier governor
Tariq ibn Ziyad led a force of approximately 7,000 men from North Africa to southern Spain in 711. Ibn Abd al-Hakam reports, one and a half centuries later, that "the people of Andalus did not observe them, thinking that the vessels crossing and recrossing were similar to the trading vessels which for their benefit plied backwards and forwards". They defeated the Visigothic army, led by King Roderic, in a decisive
battle at Guadalete in July that year. In 712, Tariq's forces were then reinforced by those of his superior, the
wali Musa ibn Nusayr, who planned a second invasion, and within a few years both took control of more than two-thirds of the
Iberian Peninsula. The second invasion comprised 18,000 mostly Arab troops, who rapidly captured
Seville and then defeated Roderick's supporters at
Mérida and met up with Tariq's troops at
Talavera. The following year the combined forces continued into
Galicia and the northeast, capturing
Léon,
Astorga and
Zaragoza. According to the
Muslim historian Al-Tabari, Iberia was first invaded some sixty years earlier during the caliphate of
Uthman (
Rashidun era). Another prominent Muslim historian of the 13th century,
Ibn Kathir, quoted the same narration, pointing to a campaign led by Abd Allah bin Nafi al Husayn and Abd Allah bin Nafi al Abd al Qays in 32
AH (654 CE), but there is no solid evidence about this campaign.The Chronicle of 754 stated that "the entire army of the Goths, which had come with him [Roderic] fraudulently and in rivalry out of hopes of the Kingship, fled". This is the only contemporary account of the battle and the paucity of detail led many later historians to invent their own. The location of the battle, though not clear, was probably the
Guadalete River. Roderic was believed to have been killed, and a crushing defeat would have left the Visigoths largely leaderless and disorganized, partly because the ruling Visigoth population is estimated to have been a mere 1 to 2% of the total population. While this isolation is said to have been "a reasonably strong and effective instrument of government"; it was highly "centralised to the extent that the defeat of the royal army left the entire land open to the invaders". The resulting
power vacuum, which may have indeed caught Tariq completely by surprise, would have aided the Muslim conquest. It may have been equally welcome to the Hispano-Roman peasants who were probably – as D.W. Lomax claims – disillusioned by the prominent legal, linguistic and social divide between them and the "barbaric" and "decadent" Visigoth royal family. " in an Umayyad fresco in
Qasr Amra, modern-day Jordan (710–750) In 714, Musa ibn Nusayr headed north-west up the
Ebro river to overrun the western Basque regions and the Cantabrian mountains all the way to
Gallaecia, with no relevant or attested opposition. During the period of the second (or first, depending on the sources) Arab governor
Abd al-Aziz ibn Musa (714–716), the principal urban centres of Catalonia surrendered. In 714, his father, Musa ibn Nusayr, advanced and overran
Soria, the western Basque regions,
Palencia, and as far west as
Gijón or
León, where a Berber governor was appointed with no recorded opposition. The northern areas of Iberia drew little attention from the conquerors and were hard to defend when taken. The high western and central
sub-Pyrenean valleys remained unconquered. At this time, Umayyad troops reached
Pamplona, and the
Basque town submitted after a compromise was brokered with Arab commanders to respect the town and its inhabitants, a practice that was common in many towns of the
Iberian Peninsula. The Umayyad troops met little resistance. Considering that era's communication capabilities, three years was a reasonable time spent almost reaching the Pyrenees, after making the necessary arrangements for the towns' submissions and their future governance. Scholars have emphasized that animosity against the Visigothic rule in some regions of the Visigothic Kingdom, including to a greater extent the deep disagreements and resentment involving the local Jewish communities and the ruling authorities, weakened the kingdom and played a pivotal role in the ultimate success of the Umayyad Conquest of Iberia. ==New territorial and civil administration==
