Ruler of the county of Portugal and its first king—son and successor of Henry o
Burgundy count of Portugal, who died in 1112. He overcame the hostile force of his
mother Teresa. He won victories over the Muslims, notably at Ourique in 1139. In 1140
he declared himself King of Portugal, recognised by Castile in 1143. By 1147 he
extended his authority south to the Tagus. He took Lisbon in 1147 with aid from the
Second Crusade. He was captured by the Muslims at Badajoz 1169 but was later released.
He captured Santarem in 1171. In 1184 Yūsuf invaded Portugal but his death in that year
ended the attempt. Afonso died on 6 December and was succeeded by his son Sancho I.
AISTULF, KING OF THE LOMBARDS (d.756)
King from 749, he contributed to making the Lombard Laws, including that men
should possess arms appropriate to their wealth. In 751 he seized the Exarchate o
Ravenna from the Byzantines. Aistulf posed a threat to the papacy, invading the duchy o
Rome in 752. He was forced to accept peace but broke the agreed terms. In 754 Pope
Stephen II travelled to Francia seeking aid against him. Pepin the Short, by the Donation
of Pepin, promised to restore what the Lombards had taken. In return the pope made
Pepin and his sons patricians and recognised the dynastic change in Francia from
Merovingians to Carolingians. Carloman, brother of Pepin the Short, represented the
Lombards in negotiations but was imprisoned for his trouble. Aistulf refused to yield to
Pepin’s demands and the latter invaded Lombardy to fulfil his promise to the pope. The
Lombards were defeated in the Valley of Susa in 755 and the Franks besieged Pavia
where Aistulf took refuge. He agreed terms while Pavia was still holding out but broke
his promises within the year. Pepin with Tassilo of Bavaria invaded again in 756. Pavia
was besieged and Aistulf surrendered, dying shortly afterwards when thrown from his
horse against a tree while hunting. He left no heir. Pepin the Short initiated the process
that would lead to Frankish rule of Lombardy.
ALARIC I, KING OF THE VISIGOTHS (c.370–410)
King from 395 who sacked Rome. He established authority over the Visigoths in the
Balkans, acting as commander for the Eastern Emperor Theodosius I, fighting in the
victory at Frigidius in 394. He defeated the usurper Eugenius but rebelled against
Theodosius and moved west with his people, invading Italy in 401. He was defeated by
the Roman commander Stilicho at Pollentia in 402, making peace in 407. Alaric was
disappointed not to receive greater recognition within the Roman Empire. When Stilicho
was executed by the Western Emperor Honorius in 408, Alaric rebelled again. His people
caused devastation in Italy and attacked Rome, which he besieged three times, taking it in
410—seen as a vital moment in the collapse of the Western Empire. It was the first time
that outsiders had taken the city since the Gauls in 390 BC. Alaric planned to invade
Sicily and Africa but storms destroyed his fleet. He died at Cosenza and was buried in the
bed of the River Busentus.
AL-ASHRAF, SULTAN OF EGYPT (d.1293)
Al-Malik al-Ashraf Khalil was the son of Qalawun, whom he succeeded in 1290 as
Mamluke Sultan. Qalawun on his deathbed made him promise to continue attacking the
Christians. Al-Ashraf overcame a

state, besieging Acre in 1291. He brought a large army and a hundred siege engines,
camping opposite the Tower of the Legate. Acre fell in less than a month and was razed
