Askold and Dir
The original information about the tribe is scarce. Tivertsi and Ulichs are briefly mentioned in early Ruthenian manuscripts, 863 being the earliest reference, 944 being the latest. The "Primary Chronicle" from the "Laurentian Codex" (the oldest copy) mentions that they lived by the Dniester and Danube down to the sea (evidently, the Black Sea). The "Hypatian Codex" (later re-copy) replaces the Dniester with the Dnieper. The "Tver Chronicle" mentions them in the year 883, mentioning their fight against Askold and Dir. A number of manuscripts mention in the year 885 that they fought with Oleg of Novgorod. They are mentioned as taking part in Oleg's expeditions in 907 and in Igor's expeditions in 944, the latter year being the last reference to Tivertsi in early East Slavic manuscripts.
