The Arian Germanic tribes were generally tolerant towards Nicene Christians and other religious minorities, including the Jews. However, the Vandals tried for several decades to force their Arian beliefs on their North African Nicene subjects, exiling Nicene clergy, dissolving monasteries, and exercising heavy pressure on non-conforming Nicene Christians. The apparent resurgence of Arianism after Nicaea was more an anti-Nicene reaction exploited by Arian sympathizers than a pro-Arian development. By the end of the 4th century it had surrendered its remaining ground to Trinitarianism. In Western Europe, Arianism, which had been taught by Ulfilas, the Arian missionary to the Germanic tribes, was dominant among the Goths, Langobards and Vandals. By the 8th century, it had ceased to be the tribes' mainstream belief as the tribal rulers gradually came to adopt Nicene orthodoxy. This trend began in 496 with Clovis I of the Franks, then Reccared I of the Visigoths in 587 and Aripert I of the Lombards in 653. The Franks and the Anglo-Saxons were unlike the other Germanic peoples in that they entered the Western Roman Empire as Pagans and were converted to Chalcedonian Christianity, led by their kings, Clovis I of the Franks, and Æthelberht of Kent and others in Britain (see also Christianity in Gaul and Christianisation of Anglo-Saxon England). The remaining tribes – the Vandals and the Ostrogoths – did not convert as a people nor did they maintain territorial cohesion. Having been militarily defeated by the armies of Emperor Justinian I, the remnants were dispersed to the fringes of the empire and became lost to history. The Vandalic War of 533–534 dispersed the defeated Vandals. Following their final defeat at the Battle of Mons Lactarius in 553, the Ostrogoths went back north and (re)settled in south Austria. From the 5th to the 7th century Much of south-eastern Europe and central Europe, including many of the Goths and Vandals respectively, had embraced Arianism (the Visigoths converted to Arian Christianity in 376 through their bishop Wulfila), which led to Arianism being a religious factor in various wars in the Roman Empire. In the west, organized Arianism survived in North Africa, in Hispania, and parts of Italy until it was finally suppressed in the 6th and 7th centuries. Visigothic Spain converted to Nicene Christianity through their king Reccared I at the Third Council of Toledo in 589. Grimoald, King of the Lombards (662–671), and his young son and successor
