At some point in 1530s, Gaju Khan went to Hindustan and served under the banners of Sher Shah Sur. When Malik Ahmad died, the jirgah of Khashi tribes chose Gaju Khan as his successor. The latter surpassed his predecessor and Yousufzais gained more power and prosperity in his time. Around 1550 AD, Gaju Khan formed a great confederation of Khashi tribes and defeated the Ghoria Khels at Shaikh Tapur. In 1553 Gaju Khan besieged Sikander Khan Uzbek, the Mughal Qiladar of the fort of Peshawar. Gaju Khan had neither artillery nor firearms. His lashkar consequently, could achieve nothing against the Peshawar fort, and he lifted the siege. Next, he crossed the river Indus and raided Pindi-gheb. In another campaign he again crossed the river Indus and fully conquered Chahch Hazara and Karlugh Hazara. Sultan Ghiyas-ud-din (the ruler of Pakhli) and Sultan Adam Gakkhar sent tributes to him as token of submission.
Brig. (r) Haroon Rashid writes: "The times were favourable to him (Gaju Khan), for it was not many years after his succession to the chieftainship that Akbar was able to pay attention to the state of affairs in this territory and by that time Khan Khaju had passed away and the confederated tribes and territory, which his talent had wielded into one, again fell under the independent rule of their respective chiefs, or under the sovereignty of Emperor Akbar".
