ABSTRACT
The spread of Christianity led to the division of the Slav world. The Croats (in 700 AD) and the Poles (in 999 AD) were converted to Roman Catholicism. The Serbs (in 700 AD), Bulgars (865 AD) and Russians (988 AD) were converted to Eastern (Orthodox) Catholicism. This led in particular to strong antipathy between Russians and Poles, and also between Serbs and Croats
