About Birendra of Nepal
Shri Panch Birendra Bir Bikram Shah Dev (Nepali: वीरेन्द्र वीर विक्रम शाह देव; 29 December 1945 – 1 June 2001) was King of Nepal from 1972 until his assassination in the 2001 Nepalese royal massacre. Birendra was the first son of King Mahendra and crown princess Indra. He inherited the panchayat system from his father when he acceded the throne in 1972, ruling as Nepal's absolute monarch. Following the 1990 revolution, he disbanded the system, lifted the concurrent ban on political parties and promulgated a new constitution in which he served as head of state of a democratic constitutional monarchy. The Nepalese Civil War began in the latter part of his reign when the Communist Party of Nepal launched an insurgency in 1996. == Early life and education == Birendra was born at the Narayanhiti Royal Palace in Kathmandu as the second son of the then Crown Prince Mahendra Bir Bikram Shah Dev and his first wife, Crown Princess Indra Rajya Lakshmi Devi. Despite Birendra not being the eldest son of Mahendra, he was made crown prince and heir apparent due to Mahendra's first son, Rabindra Shah, being born when he was unmarried, and was born to a Gurung woman which made him an "illegitimate child." Birendra spent eight years studying at St Joseph's School, a Jesuit school in Darjeeling, with his brother Gyanendra. On 13 March 1955, their grandfather King Tribhuvan died and their father succeeded the Nepalese throne. With his father's ascension, Birendra became the crown prince of Nepal. In 1959, Birendra was enrolled at Eton College in the United Kingdom.
