After the Visigoths, the group that invaded the Iberian Peninsula was the Muslims, led by the Umayyad Caliphate. Their invasion took place in the year 711 CE.

To find out how long their reign lasted, we can follow these steps:

1. Identify the end of their reign: The Umayyad Caliphate ruled over various parts of the Iberian Peninsula until the establishment of the independent Emirate of Cordoba in 756 CE.

2. Calculate the duration: To find the duration, subtract the start date from the end date. In this case, the start date is 711 CE, and the end date is 756 CE.

Calculating the duration, we have:
756 CE - 711 CE = 45 years

Therefore, the reign of the Umayyad Caliphate in the Iberian Peninsula lasted for approximately 45 years.
