[1] Bebejan was head of his clan, a Ngurungaeta, at the time Europeans invaded Kulin territory.
[1] He was at the meeting which purportedly gained signatures to Batman's Treaty in 1835[2] and signed it along with seven other tribal leaders.
The contract itself is historically significant as it was the first and only documented time when Europeans negotiated their presence and occupation of Aboriginal lands directly with the traditional owners.
The fact that he was elevated over Billibelleri, his wife's uncle, is testament to the Aboriginal leadership system being merit-based, not lineal descent.
[1] Billibelleri readily became number two man (Songman) to his younger nephew and succeeded Bebejan as leader in 1836.
