Froila Arias (flourished 1056–72) was a Galician count who governed the fortress of Traba and the region of Trastámara during a tumultuous period.
[6] In early 1071, King García II defeated the rebellious count of Portugal, Nuno Mendes and was then defeated in turn and expelled from Galicia by Sancho II of Castile and Alfonso VI of León.
[7] In early 1072, Sancho forced Alfonso into exile and annexed his kingdom, but he was assassinated shortly after.
Froila was in the city of León during Alfonso's great court of 17–19 November 1072, where the king abolished a toll and reformed judicial procedures.
He may have received a competing summons from García, also returning from exile, but he apparently moved rapidly to reassert his loyalty to Alfonso.
