After the death of his father, Tihomir is appointed supreme ruler as the Grand Prince of Serbia (1166) by Byzantine Emperor Manuel I Comnenus, however, he rules jointly with his brothers.
He was the first-born child of Zavida. The lands were divided. Stracimir ruled West Morava, Miroslav ruled Zahumlje and Travunia, Stefan Nemanja was given Toplica, Ibar, Rasina and Reke.
Nemanja was also a vassal to Manuel I, through his appanage of Dubočica.
Nemanja aided the Imperial army against the Hungarians in Srem in 1164. The tie between Nemanja and Manuel I was most likely seen as a threat to Tihomir.
Stefan Nemanja built the Monastery of Saint Nicholas in Kuršumlija and the Monastery of the Holy Mother of Christ near Kosanica-Toplica, without the approval of Tihomir. Nemanja had felt that he had the free will of doing so, Tihomir disagreed, Nemanja was, or Tihomir thought that he was trying to assert independence through his relation to Manuel I. Tihomir had Nemanja chained and thrown into jail, his lands were annexed.
Nemanja"s supporters conspired to the church that Tihomir had done all this because of his disapproval of church building, thus the Church turned against Tihomir.
Nemanja managed to escape the jail, and returned to his province. Stefan Nemanja mobilizes an army, possibly with Byzantine help, and heads for the crownland. Manuel I might have been displeased with Tihomir"s acting.
Nemanja is triumphant, Tihomir and Miroslav and Stracimir are expelled to Byzantium in 1167.
The Byzantine Empire wanted to see Serbia divided by several princes as to keep it weak. Manuel I provides Tihomir with an army, coming in from Skopje.
In 1171 Nemanja manages to gather a large army and defeats them at Pantino near Zvečan, Tihomir is drowned in the River of Sitnica. The Nemanjić dynasty was named after Stefan Nemanja who ruled Serbia until 1371.
