What is "bolokhoveni"

' Bolokhoveni', also Bolokhov, Bolokhovens, or Bolokhovians , were a 13th-century ethnic group that resided in the vicinity of the Rus' principalities of Halych, Volhynia and Kiev. Their ethnic identity is uncertain; although their ethnonym identifies them as Romanians (who were called Vlachs in the Middle Ages), archeological evidence and the Hypatian Chronicle (which is the only primary source that documents their history) suggest that they were a Slavic people. Their princes, or knyazi, were in constant conflict with Daniil Romanovich, Prince of Halych and Volhynia, between 1231 and 1257. After the Mongols sacked Kiev in 1240, the Bolokhoveni supplied them with troops, but the Bolokhoveni princes fled to Poland. The Bolokhoveni disappeared after Romanovich defeated them in 1257.
