Gnaeus Julius Agricola

Agricola was appointed governor of Aquitania, a Roman province in Gaul. He administered the province for three years, focusing on legal and financial reforms. This post prepared him for higher command and demonstrated his administrative skills.

As governor of Britain, Agricola launched a campaign against the Ordovices tribe in northern Wales. He defeated them and then conquered the island of Anglesey, a stronghold of Druids and resistance, completing the Roman subjugation of Wales.

Agricola's army defeated a large Caledonian force led by Calgacus at Mons Graupius in northern Scotland. The Roman victory was decisive, but Agricola did not pursue the defeated tribes into the Highlands, leaving the conquest of Scotland incomplete.

Agricola ordered a Roman fleet to circumnavigate Britain, proving it was an island. The fleet sailed around the northern coast, encountering the Orkney Islands. This exploration provided valuable geographical knowledge and demonstrated Roman naval power.
