Question: What was the population of Seville the year that Hermeric ratified peace with Gallaeci? Passage:The Visigoths were sent in 416 by the Emperor Honorius to fight the Germanic invaders in Hispania, but they were re-settled in 417 by the Romans as foederati in Aquitania after completely defeating the Alans and the Silingi Vandals. The absence of competition permitted first, the Asdingi Vandals, and later, the Suebi, to expand south and east. After the departure of the Vandals for Africa in 429 Roman authority in the peninsula was reasserted for 10 years except in northwest where the Suevi were confined. In its heyday Suebic Gallaecia extended as far south as Merida and Seville, capitals of the Roman provinces of Lusitania and Betica, while their expeditions reached Zaragoza and Lleida after taking the Roman capital, Merida in 439. The previous year 438 Hermeric ratified the peace with the Gallaeci, the local and partially romanized rural population, and, weary of fighting, abdicated in favour of his son Rechila, who proved to be a notable general, defeating first Andevotus, Romanae militiae dux, and later Vitus magister utriusque militiae. In 448, Rechila died, leaving the crown to his son Rechiar who had converted to Roman Catholicism circa 447. Soon, he married a daughter of the Gothic king Theodoric I, and began a wave of attacks on the Tarraconense, still a Roman province. By 456 the campaigns of Rechiar clashed with the interests of the Visigoths, and a large army of Roman federates (Visigoths under the command of Theodoric II, Burgundians directed by kings Gundioc and Chilperic) crossed the Pyrenees into Hispania, and defeated the Suebi near modern-day Astorga. Rechiar was executed after being captured by his brother-in-law, the Visigothic king Theodoric II. In 459, the Roman Emperor Majorian defeated the Suebi, briefly restoring Roman rule in northern Hispania. Nevertheless, the Suebi became free of Roman control forever after Majorian was assassinated two years later. The Suebic kingdom was confined in the northwest in Gallaecia and northern Lusitania where political division and civil war arose among several pretenders to the royal throne. After years of turmoil, Remismund was recognized as the sole king of the Suebi, bringing forth a politic of friendship with the Visigoths, and favoring the conversion of his people to Arianism.

Output:
