Feudalism began to emerge in Circassians by the 4th century. As a result of Armenian, Greek and Byzantine influence, Christianity spread throughout the Caucasus between the 3rd and 5th centuries AD. During that period the Circassians (referred to at the time as "Kassogs") began to accept Christianity as a national religion, but did not abandon all elements of their indigenous religious beliefs. Circassians established many states, but could not achieve political unity. From around 400 AD wave after wave of invaders began to invade the lands of the Adyghe people, who were also known as the "Kasogi" (or Kassogs) at the time. They were conquered first by the Bulgars (who originated on the Central Asian steppes). Outsiders sometimes confused the Adyghe people with the similarly named Utigurs (a branch of the Bulgars), and both peoples were sometimes conflated under misnomers such as "Utige". Following the dissolution of the Khazar state, the Adyghe people were integrated around the end of the 1st millennium AD into the Kingdom of Alania. Between the 10th and 13th centuries Georgia had influence on the Adyghe Circassian peoples.
