After independence, city became the capital of Punjab and was later named the capital of Himachal Pradesh. Shimla came into existence from 1st Sept,1972 on the reorganisation of the districts of the state. After the reorganisation, the erstwhile Mahasu district and its major portion was merged with Shimla. Its name has been derived from the goddess Shyamala Devi, an incarnation of the Hindu goddess Kali. As of 2011 Shimla comprises 19 erstwhile hill states mainly Balson, Bushahr, Bhaji and Koti, Darkoti, Tharoch & Dhadi, Kumharsain, Khaneti & Delath, Dhami, Jubbal, Keothal, Madhan, Rawingarh, Ratesh, and Sangri.
As a large and growing city, Shimla is home to many well-recognized colleges and research institutions in India. The city has a large number of temples and palaces. Shimla is also well noted for its buildings styled in Tudorbethan and neo-Gothic architecture dating from the colonial era. History The bridge connecting Shimla with Minor Shimla, erected in 1829 by Lord Combermere, Shimla, 1850s Shimla, along with Almora, Kumaon, Garhwal, Sirmaur, Dehradun and Kangra, was invaded and captured by Prithvi Narayan Shah of Nepal.
Shortly later, the British East India Company with local kings went to war with Nepal from 1814 to 1816. At the conclusion of the war, as a result of the Sugauli Treaty, all these captured parts of North India were ceded to the British East India company. At that time, Shimla was known for the temple of Hindu Goddess Shyamala Devi, and not as a city as it is today. Not long after gaining possession of Shimla, the British began to develop the area. The Scottish civil servant Charles Pratt Kennedy built the first British summer home in the town in 1822.
Lord Amherst, the Governor-General of Bengal from 1823 to 1828, set up a summer camp here in 1827, when there was only one cottage in the town, and only ‘half a dozen’ when he left that year. There were more than a hundred cottages within ten years. Shimla soon caught the eye of Lord William Bentinck, the next Governor-General of Bengal from 1828 (later of India, when the title was created in 1833) to 1835. In a letter to Colonel Churchill in 1832, he wrote “ Simla is only four days march from Loodianah (Ludhiana), is easy of access, and proves a very agreeable refuge from the burning plains of Hindoostaun (Hindustan). Rashtrapati Niwas, Observatory Hill, Shimla, the former Viceregal Lodge, completed in 1888 now the Indian Institute of Advanced Study One of his successors, Sir John Lawrence (Viceroy of India 1864–1869), decided to take the trouble of moving the administration twice a year between Calcutta and this separate centre over 1,000 miles away, despite the fact that it was difficult to reach. Lord Lytton (Viceroy of India 1876–1880) made efforts to plan the town from 1876, when he first stayed in a rented house, but began plans for a Viceregal Lodge, later built on Observatory Hill.
A fire cleared much of the area where the native Indian population lived (the “Upper Bazaar”), and the planning of the eastern end to become the centre of the European town forced these to live in the Middle and Lower Bazaars on the lower terraces descending the steep slopes from the Ridge. The Upper Bazaar was cleared for a Town Hall, with many facilities such as library and theatre, as well as offices—for police and military volunteers as well as municipal administration.
During the “Hot Weather”, Simla was also the Headquarters of the Commander-in-Chief, India, the head of the Indian Army, and many Departments of the Government. The summer capital of the regional Government of the Punjab moved from Murree, in modern-day Pakistan, to Shimla in 1876. They were joined by many of the British wives and daughters of the men who remained on the plains. Together these formed Simla Society, which, according to Charles Allen, “was as close as British India ever came to having an upper crust. This may have been helped by the fact that it was very expensive, having an ideal climate and thus being desirable, as well as having limited accommodation. British soldiers, merchants, and civil servants moved here each year to escape from the heat during summer in the Indo-Gangetic plain. The presence of many bachelors and unattached men, as well as the many women passing the hot weather there, gave Simla a reputation for adultery, and at least gossip about adultery: as Rudyard Kipling said in a letter cited by Allen, it had a reputation for “frivolity, gossip and intrigue”.

The railway route from Kalka to Shimla, with more than 806 bridges and 103 tunnels, was touted as an engineering feat and came to be known as the “British Jewel of the Orient”.  In 2008, it became part of the UNESCO World Heritage Site, Mountain railways of India.  Not only that, there was a significant Muslim population in the region before the partition of British India.
In addition, Shimla was the capital of the undivided state of Punjab in 1871, and remained so until the construction of the new city of Chandigarh (the present-day capital of Punjab)[dubious – discuss] Upon the formation of the state of Himachal Pradesh in 1971, Shimla was named its capital. Pre-independence structures still dot Shimla; buildings such as the former Viceregal Lodge, Auckland House, Christ Church, Gorton Castle, Shimla Town Hall and The Gaiety Theatre are reminders of British rule in India.  The original Peterhoff, another Viceregal residence, burned down in 1981.
British Simla extended about a mile and a half along the ridge between Jakhoo Hill and Prospect Hill. The central spine was The Mall, which ran along the length of the ridge, with a Mall Extension southwards, closed to all carriages except those of the Viceroy and his wife. Geography Skating at Simla, c. 1905 Shimla lies in the north-western ranges of the Himalayas. It is located at 31. 61°N 77. 10°E with an average altitude of 2397. 59 meters (7866. 10 ft) above mean sea level, the city is spread on a ridge and its seven spurs. The city stretches nearly 9. km from east to west.  The highest point in Shimla, at 2454 meters (8051 ft), is the Jakhoo hill. Shimla is a Zone IV (High Damage Risk Zone) per the Earthquake hazard zoning of India. Weak construction techniques and increasing population pose a serious threat to the already earthquake prone region.  There are no bodies of water near the main city and the closest river, Sutlej, is about 21 km (13 mi) away.  Other rivers that flow through the Shimla district, although further from the city, are Giri, and Pabbar (both are tributaries of Yamuna).
The green belt in Shimla planning area is spread over 414 hectares (1023 acres).  The main forests in and around the city are that of pine, deodar, oak and rhododendron.  Environmental degradation due to the increasing number of tourists every year without the infrastructure to support them has resulted in Shimla losing its popular appeal as an ecotourism spot.  Another rising concern in the region are the frequent number of landslides that often take place after heavy rains.  Climate
Shimla features a subtropical highland climate under the Koppen climate classification. The climate in Shimla is predominantly cool during winters, and moderately warm during summer. Temperatures typically range from ? 4 °C (25 °F) to 31 °C (88 °F) over the course of a year.  The average temperature during summer is between 19 °C (66 °F) and 28 °C (82 °F), and between ? 1 °C (30 °F) and 10 °C (50 °F) in winter. Monthly precipitation varies between 15 millimetres (0. 59 in) in November to 434 millimetres (17. in) in August. It is typically around 45 millimetres (1. 8 in) per month during winter and spring and around 175 millimetres (6. 9 in) in June as the monsoon approaches. The average total annual precipitation is 1,575 millimetres (62 in), which is much less than most other hill stations but still greatly heavier than on the plains. Snowfall in the region, which historically has taken place in the month of December, has lately (over the last fifteen years) been happening in January or early February every year.  Economy
