The All Flags Navy was a multinational navy headed by a Colovian, the King of Anvil Bendu Olo.
The All Flags Navy was formed in response to the devastating Thrassian Plague. The force, formed circa 1E 2200, is the largest naval force ever assembled in Tamrielic history.[1]
The All Flags Navy sailed to the Coral Kingdom of Thras where any Sload that could be found were put to death. This was brutally effective; the Sload were not seen in force again, limited to harassing the Redguards of Stros M'kai.[1][2] This victory would bring the Cyrodiilic people, particularly members of the Colovian Estates, to be known around Tamriel. This would lead to increased power over the Nibenay Valley, eventually leading to the War of Righteousness.[3]
