In 1719 A. D. BahadurKhan was appointed Foujdar ( Governor ) of the neighboring places of AHMEDABAD City. He discharged his duties creditably. BAHADURKHAN performed a long series of important deeds in Gujrat, in discharge of his duties to the Empire. In consequence of this he was exalted to the title of SHERKHAN by the Imperial Government in 1721 A.D. In 1728 A. D. he was appointed Nayab Foujdar of JUNAGADH in his father’s place. In 1732 A.D. he was promoted to the post of Foujdar of BARODA.

In appreciation of his excellent services he was created NAWAB by the Emperor Muhammad Shah, Subsequently in 1734 A. D. he was appointed the Foujdar of VIRAMGAM. At this time the affairs at JUNAGADH being in a state of confusion, the Government dues were not paid regularly and the Marathas devastated the country. Thereupon in 1738 A.D. Sherkhan was sent there as Nayab under Imperial Orders. The Nawab spent five years in settling the Kathiawar territory and having subdued rebels brought peace in the country. Afterwards he went to AHMEDABAD and other places for the purpose of helping the Subas. When Sherkhan saw that Gujarat was going from bad to worse and was on the verge of falling into the hands of the Marathas, he did not think it advisable to tarry there longer. Therefore handing over WADASINOR to his son SARDAR Muhammad KHAN, he went to JUNAGADH in the year 1748 A. D.

During his absence from Junagadh the administration was conducted by his wives LADLI BEGAM and AMINA BEGAM. Sherkhan died in 1758 and was buried in the Mausoleum opposite the CHITAKHAN Mosque in Junagadh. Sherkhan served for 30 years at various places in Gujarat. That time was very critical, because many battles were then fought between the Muslims and Marathas, and every officer was aiming at the highest authority. In the beginning Sherkhan obtained the FOUJDARI and JAGIR of JUNAGADH because of his having rendered valuable services to the Emperor. At Junagadh he established order, the country was prosperous and the subjects happy. Through his own efforts he subjugated all the states in Kathiawar and exacted a tribute from them since called “ZORTALABI” which continued till 1947. He was religious, just and magnanimous. He gave Jagirs to Syeds, learned men and others deserving them. He was so impartial that he also bestowed Jagirs upon Hindus. He accorded permission to a Kathi named WALA WIRA to construct a fort and assigned him the Paragna of Jetpur as Jagir on condition of remaining faithful. It still continuous in his family.

He gave KOYLI as Jagir to the Mahant of Koyli. Upon his brothers SHERZAMANKHAN and DILERKHAN he bestowed the Taluka of BANTWA as Jagir. It is now divided into three smaller Talukas. Of these two BANTWA and SARDARGADH (or Ghidar) are in the possession of the descendants of SHERZAMANKHAN. Each consists of twelve villages. But BANTWA is now subdivided into many small parts. The third, MANAVADAR, is in the hands of the descendants of DILERKHAN. It consists of 24 villages. Nawab Sherkhan had two Begams ( wives ). One of them was AMINA BEGAM, daughter of Muhammad Khan, Jagirdar of Kaira and the other LADLI BEGAM, daughter of Sardar Muhammad Khan Ghori, Foujdar of Baroda. The Nawab Sahib had four sons. The eldest of these MAHABATKHAN, became the Nawab Sahib of JUNAGADH and the second, SARDAR Muhammad KHAN, Nawab of WADASINOR.
