Jaisalmer, nicknamed "The Golden City", is a town in the Rajasthan state of western side of India. The town stands on a ridge of yellowish sandstone, crowned by a fort, which contains the palace and several ornate Jain temples. Many of the houses and temples are finely sculptured. It lies in the heart of the Thar Desert and has a population of about 78,000. It is the administrative headquarters of Jaisalmer District. Originally, the place was known as Jaysalmar named after its founder Rao Jaysal. "Jaisalmer" means "the Hill Fort of Jaisal".
Past to present:
The majority of the inhabitants of Jaisalmer are Bhatti Rajputs, who take their name from an ancestor named Bhatti, renowned as a warrior when the tribe were located in the Punjab. Shortly after this the clan was driven southwards, and found a refuge in the Indian desert, which was henceforth their home. This area was part of Gurjar - Pratihara empire and until the 11th century was ruled by a powerful Bargujar King. Deoraj, a famous prince of the Bhati family, is esteemed the real founder of the Jaisalmer dynasty, and with him the title of rawal commenced. In 1156 Rawal Jaisal, the sixth in succession from Deoraj, founded the fort and city of Jaisalmer, and made it his capital as he moved from his former capital at Lodhruva (which is situated about 15 km to the north-west of Jaisalmer). In 1293, the Bhattis so enraged the emperor Ala-ud-din Khilji that his army captured and sacked the fort and city of Jaisalmer, so that for some time it was quite deserted. Some Bhatti's migrated to Talwandi, now Nankana Sahib in Distt. Nankana Sahib (Punjab, Pakistan) and others settled in Larkana (in Sind, Pakistan) under the name of Bhutto. In Nankana Sahib, the Bhatti Clan can be traced from the lineage of Rai Bhoe and Rai Bular Bhatti. There is nothing to record until the time of Rawal Sahal Singh, whose reign marks an epoch in Bhatti history in that he acknowledged the supremacy of the Mughal emperor Shah Jahan. The Jaisalmer princes had now arrived at the height of their power, but from this time till the accession of Rawal Mulraj in 1762 the fortunes of the state rapidly declined, and most of its outlying provinces were lost. In 1818 Mulraj entered into political relations with the British. Maharawal Salivahan, born in 1887, succeeded to the chiefship in 1891.
The Maharajas of Jaisalmer trace their lineage back to Jaitsimha, a ruler of the Bhatti Rajput clan. The major opponents of the Bhati Rajputs were the powerful Rathor clans of Jodhpur and Bikaner. They used to fight battles for the possession of forts,  waterholes or cattle. Jaisalmer was positioned strategically and was a halting point along a traditional trade route traversed by the camel caravans of Indian and Asian merchants. The route linked India to Central Asia, Egypt, Arabia, Persia, Africa and the West.
During the Islamic invasion of India, Jaisalmer escaped direct Muslim conquest due to its geographical situation in the desert region. The Rawals of Jaisalmer agreed to pay an annual tribute to the Delhi Sultans. The first siege of Jaisalmer occurred during the reign of Alauddin Khilji. It was provoked by Bhatis' raid on a caravan filled with treasure. According to local ballads, the Bhatis defended the fort for seven years until the enemy army forced beached the ramparts. Bhatis, facing certain defeat, proclaimed the rite of jauhar. Later, Sultan Ferozshah also sieged Jaisalmer after the rulers of Jaisalmer raided his camp at Anasagar lake near Ajmer. The siege led to another jauhar. Jaitsimha's son Duda died in the attack. Duda's descendants ruled over Jaisalmer for about two centuries. Duda's descendant Lunakarna had a fight with Humayun when the latter passed through Jaisalmer en-route to Ajmer. Mughal emperor Akbar was married to one of the Jaisalmer princesses.
Later, Jaisalmer was ruled by a noble called Sabala Simha, who won the patronage of the Mughal emperor Shah Jahan for services rendered in his Peshawar campaign.
Jaisalmer was one of the last states to sign a treaty with the British. During the British Raj, Jaisalmer was the seat of a princely state of the same name, ruled by the Bhati clan of rajputs. The present descendant is Brijraj Singh. Though the city is under the governance of the Government of India, a lot of welfare work is carried out by him and his family. The Royal Family still commands a lot of respect from the people.
Traditionally, the main source of income was the levies on the caravans. However, the glory of Jaisalmer faded when Bombay emerged as a port and the sea trade replaced the traditional land routes. The partition of India in 1947 lead to closing of all the trade routes on the Indo-Pak border and rendered Jaisalmer a drought-prone desert backwater on the international border. Ironically, skirmishes between India and Pakistan gave Jaisalmer a strategic importance and made it serviceable as an army supply depot. Later, the Rajasthan Canal served to revive the surrounding desert areas. Roads and railroads were then built, knitting the hitherto remote town with the rest of Rajasthan. Later, the Government of Rajasthan decided to promote Jaisalmer as a tourist destination.
Geography:
Jaisalmer has an average elevation of 229 metres (751 ft). It is situated near the border of India and Pakistan in West Rajasthan, and covers an area of 5.1 km². Geographically, it belongs to the Thar desert area. Jaisalmer is almost entirely a sandy waste, forming a part of the great Indian desert. The general aspect of the area is that of an interminable sea of sand hills, of all shapes and sizes, some rising to a height of 150 feet (46 m). Those in the west are covered with log bushes, those in the east with tufts of long grass. Water is scarce, and generally brackish; the average depth of the wells is said to be about 250 feet (76 m). There are no perennial streams, and only one small river, the Kakni, which, after flowing a distance of 28 metres (92 ft), spreads over a large surface of flat ground, and forms Lake Orjhil ("The Bhuj-Jhil"). The climate is dry and healthy. Throughout Jaisalmer only raincrops, such as bajra, jawar, motif, til, etc., are grown; spring crops of wheat, barley, etc., are very rare. Owing to the scant rainfall, irrigation is almost unknown.

Distances: Jaipur (558 km), Ahmedabad (626 km), Agra (802 km), NewDelhi (864 km), Mumbai (1177 km).
Tourism
While Jaisalmer may always have been remote, it is filled with many artistic structures and monuments of local historical importance. Jaisalmer's medieval mud fortress and walled township make it a popular tourist destination. The surrounding desolate landscape evidences a stark, austere beauty. Camel safaris through the nearby desert dunes are popular with tourists; competition for business is fierce. A few quiet days spent wandering around the town and the surrounding desert can be a wonderful way of unwinding from the chaos of larger Indian cities.

Jaisalmer Fort

Built in 1156 by the Bhati Rajput ruler Jaisal, Jaisalmer Fort is situated on Trikuta Hill and had been the scene of many battles. Its massive sandstone walls are a tawny lion colour during the day, turning to a magical honey-gold as the sun sets. The famous Indian film director Satyajit Ray wrote a detective novel and later turned it into a film – Sonar Kella (The Golden Fortress) which was based on this fort. This is a living fort and about a quarter of city's population still live inside the fort. The main attractions inside the fort are: Raj Mahal (Royal palace), Jain temples and the Laxminath temple.
Havelies are worth seeing in Jaisalmer:
Patwon-ki-Haveli: Guman Chand Patwa (and later by his five sons), a wealthy merchant belonging to powerful Oswal Jain community and banker who had over three hundred trading centres from Afghanistan to China. This ornate five-storey complex took fifty years to complete. This is the largest, the most magnificent, and the most elaborate of Jaisalmer havelis.[7]
Salam Singh-ki-Haveli: It was built by the scheming Prime Minister Salam Singh in 1815. It has a beautifully arched roof capped with blue cupolas and carved brackets in the form of peacocks.
