Khatan Gujjar

Khatana Gotra belong to Gujjar Kusha Era and Gujjar Khatana rulers used the same title as Gujjar Kushans.

Rajatiraya ( Rajaon ka Raja) and Saha-nu Shahi ( Shahon ka Shah) were the title used by the Gujjars during the days of Gujjar Kushan Empire. Later the same title was used by Gujjar Pratihar as PMP ( Param Bhattaraka Maharajadhiraja Parmeshwar). The Mughals copied the title of Gujjar Kushans as Shah-nu-Sahi or Shahanshah, since they were ruled by the Gujjars during the Gujjar Kushan Empire.
Samarkand was the winter capital of Gujjar Kushan which is located in Uzbekistan, the birth place of Babar.
Here is the historical evidence of Gujjar Emperor Vijai Singh Khatana.
The first concrete evidence of an Iranian presence in the country is found in a document probably of the 3rd century, discovered by M. A. Stein at the site of Endere (facsimile in Stein, 1921, pl. xxxviii; transcription in Boyer and Senart, p. 249; tr. 1940, p. 137; cf. Emmerick, 1979, p. 168 and n. 7). It was written in a local Middle Indian dialect in Kharoṣṭhî script by Khotana maharaya rayatiraya hinajha Vij’ida Siṃha “General Vijida Simha, great king, king of kings of Khotan” in his tenth chuna (< Khot. kṣuṇa) “regnal year.” The Khotanese title hînâysa (pronounced hînâza, lit. “army leader”) is also attested in much later indigenous texts.
This imformation is taken from one of the Iranian records.
That confirm that Iran was also under Gujjar control during the Gujjar Kushan Empire.
I would like to mention that the Gujjar Gotras of Kasana and Khatana are mentioned in the original Kushan inscriptions as "Kasano" and "Khatano" as spoken among Gujjars in Gojari language even today.
