Modern-day Gujarat is derived from Sanskrit (Gurjar-Rashtra), the Gurjar nation. Parts of Rajasthan and Gujarat have been known as Gurjaratra (country ruled or protected by the Gurjars) or Gurjarabhumi (land of the Gurjars) for centuries prior to the Mughal period. Historically, the Gurjars were Sun-worshipers and are described as devoted to the feet of the Sun-god (God Surya). Their copper-plate grants bear an emblem of the Sun and on their seals too, this symbol is depicted. Many Gurjars claim descent from Suryavanshi Kshatriyas (Sun Dynasty) and connect themselves with the Hindu deity Rama. The Gujjar clan appeared during the 7th to 8th century in Northern India about the time of the Huna invasions. The origins of the Gujjars are uncertain. The name of the tribe was Sanskritised to - Gurjara.
