Who was the king prithivi Narayan shah
​

Explanation:

Maharajadhiraj Prithivi Narayan Shah was the last ruler of the Gorkha Kingdom and first monarch of Kingdom of Nepal.

                          Prithvi Narayan Shah started the unification of Nepal. Shah proclaimed the newly unified Kingdom of Nepal as Asal Hindustan due to North India being ruled by the Islamic Mughal rulers.In 1742 Prithvi Nārāyaṇ became king of Gurkha. An ambitious ruler, he was able to quickly enlarge his territory by conquering the quarrelsome and disunited principalities around Gurkha. Prithvi Nārāyaṇ’s initial attempts to establish hegemony over the three Malla kingdoms were abortive, however; the raja of Kāthmāndu enlisted the aid of the East India Company in 1767 and was able to repulse Prithvi Nārāyaṇ’s encroachments. Two years later, however, after the company’s forces had been recalled, Kāthmāndu was taken. This allowed Prithvi Nārāyaṇ to consolidate his territories into a new “Kingdom of Nepal,” which he made into a unified, strong, and independent state. He then annexed Tarai.

   Prithvi Nārāyaṇ sealed his border and maintained peaceful but distant relations with the British, refusing to trade with them. He died before he could effectively organize the administration of his new country. Upon his death, Prithvi Nārāyaṇ was succeeded by his son, Pratāp Singh Shah.
