The exact date of creation of the Kiev Metropolis is uncertain, as well as who was the first leader of the church. Predominantly it is considered that the first head was Michael I of Kiev, however some sources also claim Leontiy who is often placed after Michael or Anastas Chersonesos, became the first bishop of the Church of the Tithes. The first metropolitan to be confirmed by historical sources is Theopemp, who was appointed by Patriarch Alexius of Constantinople in 1038. Before 1015 there were five dioceses: Kiev, Chernihiv, Bilhorod, Volodymyr, Novgorod, and soon thereafter Yuriy-upon-Ros. The Kiev Metropolitan sent his own delegation to the Council of Bari in 1098.
