Uttarakhand's history dates back to prehistoric times, with archaeological evidence showcasing human habitation. It was part of the ancient Kuru and the Panchal kingdoms during the Vedic age, and later saw the rise of dynasties like the Kunindas and influence of Buddhism as evidenced by Ashokan edicts. Though primarily driven by agriculture and hydropower, the state's economy is now dominated by the service industry. The service sector comprises primarily travel, tourism, and hotel industry. The Gross State Domestic Product (GSDP) of Uttarakhand is ₹2.87 lakh crore (US$33 billion). The state contributes five seats to the lower house Lok Sabha and three seats to the upper house Rajya Sabha.
Inhabitants of the state are called either Garhwali or Kumaoni depending on their region of origin. Hinduism is practiced by more than three-fourths of the population, with Islam being the next-largest religious group. Hindi is the most widely spoken language and is also the official language of the state, along with native regional languages include Garhwali, Jaunsari, Gurjari and Kumaoni. The state is often referred to as the "Devbhumi" (lit. 'Land of the Gods'), due to its religious significance and numerous Hindu temples and pilgrimage centres found throughout the state. Along with several historical, natural and religious tourist destinations, including Char Dham, Haridwar, Rishikesh, Panch Kedar, Himalayas, and Sapta Badri. Uttarakhand is also home to two World Heritage sites.
Archaeological evidence supports the existence of humans in the region since prehistoric times.[24] Though initially, it was believed that due to harsh climate and mountainous terrain, this was a barren and uninhabited land. But after various excavations and the study of ancient literature, it is now established that the history of Uttarakhand goes back to Stone Age.[25] Evidences of Stone Age settlements have been found in various parts of Kumaon and Garhwal, particularly notable are the rock shelters at Lakhudyar, Almora.[26
The region formed a part of the Uttarakuru Kingdom during the Vedic age of Ancient India. Among the first major dynasties of Kumaon were the Kunindas in the second century BCE who practised an early form of Shaivism. Ashokan edicts at Kalsi show the early presence of Buddhism in this region.
Ancient rock paintings, rock shelters, paleolithic age stone tools (hundreds of thousands of years old), and megaliths provide evidence that the mountains of the region have been inhabited since prehistoric times. There are also archaeological remains that show the existence of early Vedic (c. 1500 BCE) practices in the area.[27] The Pauravas, Khasas, Kiratas, Nandas, Mauryas, Kushanas, Kunindas, Guptas, Karkotas, Palas, Gurjara-Pratiharas, Katyuris, Raikas, Chands, Parmars or Panwars, Mallas, Shahs and the British have ruled Uttarakhand in turns.[23]
Among the first major dynasties of Garhwal and Kumaon were the Kunindas in the second century BCE who practised an early form of Shaivism and traded salt with Western Tibet. It is evident from the Ashokan edict at Kalsi in Western Garhwal that Buddhism made inroads in this region. Shamanic Hindu practices deviating from Hindu orthodoxy also persisted here. However, Garhwal and Kumaon were restored to nominal Vedic Hindu rule due to the travels of Shankaracharya and the arrival of migrants from the plains.[citation needed]
