Beastman Commonwealth

Beastman Commonwealth (ビーストマンの連邦) is a demi-human nation in the New World, which is made up of several beastmen tribes. It is located in the central continent.

Background
The Beastman Country was founded by an unknown beastman at an unspecified time. Sometime before the Massacre at Katze Plains, the Commonwealth invaded the Great Minotaur Nation.

Overlord Second Half Arc
The Beastman Commonwealth was mentioned by Rangobart Eck Waria Roberbad during his inner dialogue as he admired the Death Knight under the command of the Archduke Ainz Ooal Gown. He compared them to the golems used by the Commonwealth.

Culture
So far its cultural aspect has yet to be touched upon.

Foreign Relations
Since the Commonwealth is located in the central continent, a region where demi-humans regard humans as slaves or food, it possible that this nation holds these views. On the other hand, there are reports that the Commonwealth has taken aggressive stances on its neighbors.

Great Minotaur Nation
In the Web Novel, the Beastman Country once used their golems to launch an attack on the Great Minotaur Nation. The battle with the minotaurs caused the Beastman Country to lose four of its eight centaur bodied golem cavalry.

Military Strength
It's mentioned that the Commonwealth is famous for possessing 8-meter centaur-type golems. Golems are seen as decisive weapons for their country. If it was not for the weapons left by the so-called Minotaur Sage in the Great Minotaur Nation, the Beastman Commonwealth may have been able to destroy that nation with a few of their golems. They were Golems of that strength which possesses overwhelming power.

Trivia

 * According to one of Maruyama's tweets, more than just one "Beastman Country" alone exists in the New World. Because of that, there are several countries of beastman just like there are several human countries. The Beastman Country originated outside of the mainland continent. Moreover, the country of beastman attacking the Dragon Kingdom is different from the country of beastman in the center of the continent.
 * Maruyama had pointed out in an interview that one of the main reasons he created Gargantua for the series was to have it fight the Golem Calvary that the commonwealth nation had in its possession should the story have ever reached that point.
