History of Nepal

In the mid-18th century, Prithvi Narayan Shah, a Gorkha king, set out to put together what would become present-day Nepal. He embarked on his mission after seeking arms and aid from India and buying the neutrality of bordering Indian kingdoms. After several bloody battles and sieges, notably the Battle of Kirtipur, he managed to conquer the Kathmandu Valley in 1769. A detailed account of Prithvi Narayan Shah's victory was written by Father Giuseppe who was an eyewitness to the war.
In 1788 the Nepalese overran Sikkim and sent a punitive raid into Tibet. Kangra in northern India was also occupied by the Nepalese. In 1809, Ranjit Singh the ruler of the Sikh state in the Punjab, had intervened and drove the Nepalese army east of the Satluj river.
At its maximum extent, Greater Nepal extended from the Tista River in the east, to Kangara, across the Sutlej River in the west as well as further south into the Terai plains and north of the Himalayas than at present. A dispute with Tibet over the control of mountain passes and inner Tingri valleys of Tibet forced the Qing Emperor in Peking to start the Sino-Nepalese War compelling the Nepalese to retreat and pay heavy reparations to Peking.
Rivalry between Nepal and the British East India Company over the annexation of minor states bordering Nepal eventually led to the Anglo-Nepalese War (1815–16). At first the British underestimated the Nepalese and were soundly defeated until committing more military resources than they had anticipated needing. They were greatly impressed by the valour and competence of their adversaries. Thus began the reputation of "Gurkhas" as fierce and ruthless soldiers. The war ended in the Treaty of Sugauli, under which Nepal ceded recently captured portions of Sikkim and lands in Terai as well as the right to recruit soldiers. Madheshis, though having supported the British East India Company during the war, had their lands gifted to Nepalese.
Factionalism inside the royal family had led to a period of instability. In 1846 a plot was discovered revealing that the reigning queen had planned to overthrow Jung Bahadur Kunwar, a fast-rising military leader. This led to the Kot Massacre; armed clashes between military personnel and administrators loyal to the queen led to the execution of several hundred princes and chieftains around the country. Jung Bahadur Kunwar emerged victorious and founded the Rana Lineage and was later known as Jung Bahadur Rana.
The king was made a titular figure, and the post of Prime Minister was made powerful and hereditary. The Ranas were staunchly pro-British and assisted them during the Indian Sepoy Rebellion in 1857 (and later in both World Wars). Some parts of the Terai Region populated with non-Nepalese peoples were gifted to Nepal by the British as a friendly gesture, because of her military help to sustain British control in India during the Sepoy Rebellion. In 1923, the United Kingdom and Nepal formally signed an agreement of friendship, which superseded the Sugauli Treaty signed in 1816.
In the late 1940s, newly emerging pro-democracy movements and political parties in Nepal were critical of the Rana autocracy. Meanwhile, with the invasion of Tibet by China in the 1950s, India sought to counterbalance the perceived military threat from its northern neighbour by taking pre-emptive steps to assert more influence in Nepal. India sponsored both King Tribhuvan (ruled 1911–55) as Nepal's new ruler in 1951 and a new government, mostly comprising the Nepali Congress Party, thus terminating Rana hegemony in the kingdom.
After years of power wrangling between the king and the government, King Mahendra (ruled 1955–72) scrapped the democratic experiment in 1959, and a "partyless" Panchayat system was made to govern Nepal until 1989, when the "Jan Andolan" (People's Movement) forced King Birendra (ruled 1972–2001) to accept constitutional reforms and to establish a multiparty parliament that took seat in May 1991. In 1991–92, Bhutan expelled roughly 100,000 Bhutanese citizens of Nepali descent, most of whom have been living in seven refugee camps in eastern Nepal ever since^.
In 1996, the Communist Party of Nepal (Maoist) started a bid to replace the royal parliamentary system with a people's socialist republic by violent means. This led to the long Nepal Civil War and more than 12,000 deaths. On 1 June 2001, there was a massacre in the royal palace. King Birendra, Queen Aiswarya, and seven other members of the royal family were killed. The perpetrator was Crown Prince Dipendra, who committed suicide (he died three days later) shortly thereafter. This outburst was alleged to have been Dipendra's response to his parents' refusal to accept his choice of wife. Nevertheless there are speculation and doubts among Nepalese citizens about who was responsible.
Following the carnage, Birendra's brother Gyanendra inherited the throne. On 1 February 2005, Gyanendra dismissed the entire government and assumed full executive powers to quash the violent Maoist movement, but this initiative was unsuccessful because a stalemate had developed where the Maoists were firmly entrenched in large expanses of countryside yet could not dislodge the military from numerous towns and the largest cities. In September 2005, the Maoists declared a three-month unilateral ceasefire to negotiate.
In response to the 2006 democracy movement King Gyanendra agreed to relinquish sovereign power to the people. On 24 April 2006 the dissolved House of Representatives was reinstated. Using its newly acquired sovereign authority, on 18 May 2006 the House of Representatives unanimously voted to curtail the power of the king and declared Nepal a secular state, ending its time-honoured official status as a Hindu Kingdom. On 28 December 2007, a bill was passed in parliament to amend Article 159 of the constitution – replacing "Provisions regarding the King" by "Provisions of the Head of the State" – declaring Nepal a federal republic, and thereby abolishing the monarchy. The bill came into force on 28 May 2008.
