He also describes each tribe separately to show their differences, as well as to tell readers which tribes are loyal to Rome, and which are a threat to Roman society. Tacitus stresses their overwhelming sense of family, their abilities to fight, and their passion for freedom several times, showing his belief that these forces make the people of Germany particularly dangerous. Described as being of Celtic, Gaul, and indigenous decent, the people of Germany are described first in terms of their dress, traditions, and overall culture.

In the second part of the book, Tacitus tells of what he believes to be the greatest threat to Rome, that of the people of Germany. Tacitus' use of style and description within the story show Agricola not just as a military force, but as a kind and tempered military genius. Finally, he tells of Agricola's fall from grace with the ruling Emperor of Rome, and his eventual death. Tacitus tells of Agricola's early years in training for the military, his rise in the ranks, and his unparalleled victory over the British rebel forces at the time. Although Tacitus is limited in his knowledge of geography and military history, his knowledge of the life of Agricola is unmatched in any other tribute. Due to his status as Agricola's son-in-law, Tacitus tells the story of Agricola's rise to power over Britain using both his own personal experiences with the man as well as stories from Agricola himself. First, the book serves to pay tribute to one of the greatest commanders over Britain in Roman history, that of Commander Agricola. The Agricola and the Germania, by Cornelius Tacitus, serves two purposes as a historical document.
