It is believed that he was the son of a German nobleman Gotfrid, founder of the family he belonged to Kelad went to strengthen the Hungarian hold in Bosnia in 1162 or 1163.
This German nobleman co-signed the edicts for Bosnia in the Split Church in 1163 with the Hungarian King Stephen IV.
Apparently, the Hungarian King Stephen III invited him to place him as a regional ruler in Hungary's name because of his ancestor's successes.
The marriage was political and arranged by Ban Prijezda II who had attempted to forge an alliance with Stefan Dragutin.
The latter party had much more support, so Pope Nicholas IV had crowned Charles Martel as King of Hungary.
To increase his influence in Kotroman's realm, Charles Martel issued numerous edicts to split the land among the lesser gentry to gain support for his reign.

The war turned into religious conflict, as Mladen I Šubić had started a campaign to exterminate the adherents of the Bosnian Church – the kristjani.
