Agra (Hindi: आगरा, Urdu: آ گرہ), the erstwhile capital of Hindustan, is a city on the banks of the river Yamuna in the northern state of Uttar Pradesh, India, 363 kilometres (226 mi) west of state capital, Lucknow and 200 kilometres (124 mi) south of the national capital New Delhi. With a population of 1,686,976 (2010 est.), it is one of the most populous cities in Uttar Pradesh and the 19th most populous in India.Because 80 percent of the city's sewage flows into Yamuna River, it is 20th most polluted city in India. Agra can also refer to the administrative district that has its headquarters in Agra city.
The city finds mention in the epic Mahābhārata where it was called Agrevaṇa, or 'the border of the forest'.Legend ascribes the founding of the city to Rājā Badal Singh, a Sikarwar Rajput king (circa 1475), whose fort, Badalgarh, stood on or near the site of the present Fort. However, the 11th century Persian poet Mas'ūd Sa'd Salmān writes of a desperate assault on the fortress of Agra, then held by the Shāhī King Jayapala, by Sultan Mahmud of Ghazni.Sultan Sikandar Lodī was the first to move his capital from Delhi to Agra in the year 1506; he died in 1517 and his son Ibrāhīm Lodī remained in power there for nine more years, finally being defeated at the Battle of Panipat in 1526.[5] It achieved fame as the capital of the Mughal emperors from 1526 to 1658 and remains a major tourist destination because of its many splendid Mughal-era buildings, most notably the Tāj Mahal, Agra Fort and Fatehpūr Sikrī, all three of which are UNESCO World Heritage Sites.

History
Though Agra's history is largely recognised with Mughal Empire, the place was established much before it and has linkages since Mahabharat period and Mahirshi Angira in 1000 BC. It is generally accepted that Sultan Sikandar Lodī, the Ruler of the Delhi Sultanate founded Agra in the year 1504. After the Sultan's death the city passed on to his son Sultan Ibrāhīm Lodī. He ruled his Sultanate from Agra until he fell fighting to Bābar in the First battle of Panipat fought in 1526.
In the year 1556, the great Hindu warrior Hemu Vikramaditya, also known as Samrat Hem Chander Vikramaditya, won Agra as the Prime Minister cum Chief of Army of Adil Shah of the Afghan Sūrī Dynasty. The commander of Humāyūn / Akbar's forces in Agra, Tardi Beg Khan, was so scared of Hemu that he retreated from the city without a fight. This was Hemu's 21st continuous win since 1554, and he later went on to conquer Delhi, having his coronation at Purānā Qil'a in Delhi on 7 October 1556 and re-established the Hindu Kingdom and the Vikramaditya Dynasty in North India.
The golden age of the city began with the Mughals. It was known then as Akbarabād and remained the capital of the Mughal Empire under the Emperors Akbar, Jahāngīr and Shāh Jahān. Shāh Jahān later shifted his capital to Shāhjahānabād in the year 1649.
Since Akbarabād was one of the most important cities in India under the Mughals, it witnessed a lot of building activity. Babar, the founder of the Mughal dynasty, laid out the first formal Persian garden on the banks of river Yamuna. The garden is called the Arām Bāgh or the Garden of Relaxation. His grandson Akbar raised the towering ramparts of the Great Red Fort, besides making Agra a center for learning, arts, commerce and religion. Akbar also built a new city on the outskirts of Akbarabād called Fatehpūr Sikrī. This city was built in the form of a Mughal military camp in stone.
His son Jahāngīr had a love of gardens and flora and fauna and laid many gardens inside the Red Fort or Lāl Qil'a. Shāh Jahān, known for his keen interest in architecture, gave Akbarabād its most prized monument, the Tāj Mahal. Built in loving memory of his wife Mumtāz Mahal, the mausoleum was completed in 1653.
Shāh Jahān later shifted the capital to Delhi during his reign, but his son Aurangzeb moved the capital back to Akbarabād, usurping his father and imprisoning him in the Fort there. Akbarabād remained the capital of India during the rule of Aurangzeb until he shifted it to Aurangabad in the Deccan in 1653. After the decline of the Mughal Empire, the city came under the influence of Marathas and Jats and was called Agra, before falling into the hands of the British Raj in 1803.


In 1835 when the Presidency of Agra was established by the British, the city became the seat of government, and just two years later it was witness to the Agra famine of 1837–38. During the Indian rebellion of 1857 British rule across India was threatened, news of the rebellion had reached Agra on 11 May and on 30 May two companies of native infantry, the 44th and 67th regiments, rebelled and marched to Delhi. The next morning native Indian troops in Agra were forced to disarm, on 15 June Gwalior (which lies south of Agra) rebelled. By 3 July the British were forced to withdraw into the fort. Two days later a small British force at Sucheta were defeated and forced to withdraw, this led to a mob sacking the city. However, the rebels moved onto Delhi which allowed the British to restore order by 8 July. Delhi fell to the British in September, the following month rebels who had fled Delhi along with rebels from Central India marched on Agra but were defeated. After this British rule was again secured over the city until the independence of India in 1947.
Agra is the birthplace of the religion known as Dīn-i Ilāhī, which flourished during the reign of Akbar and also of the Radhaswami Faith, which has around two million followers worldwide. Agra has historic linkages with Shauripur of Jainism and Runukta of Hinduism, of 1000 BC.


Taj Mahal

The Taj Mahal (Hindi: ताज महल, from Persian/Urdu: تاج محل "crown of palaces", pronounced [ˈt̪aːdʒ mɛˈɦɛl]; also "the Taj"[2]) is a white marble mausoleum located in Agra, India. It was built by Mughal emperor Shah Jahan in memory of his third wife, Mumtaz Mahal. The Taj Mahal is widely recognized as "the jewel of Muslim art in India and one of the universally admired masterpieces of the world's heritage.It coveres area about 221 hectare (552 Acres) which include 38 hectare taj mahal and 183 hectare taj protected forest are."
Taj Mahal is the finest example of Mughal architecture, a style that combines elements from Persian, Turkish and Indian architectural styles.[4][5]
In 1983, the Taj Mahal became a UNESCO World Heritage Site. While the white domed marble mausoleum is the most familiar component of the Taj Mahal, it is actually an integrated complex of structures. The construction began around 1632 and was completed around 1653, employing thousands of artisans and craftsmen.The construction of the Taj Mahal was entrusted to a board of architects under imperial supervision, including Abd ul-Karim Ma'mur Khan, Makramat Khan, and Ustad Ahmad Lahauri.Lahauri is generally considered to be the principal designer.

Origin and inspiration
Main article: Origins and architecture of the Taj Mahal
In 1631, Shah Jahan, emperor during the Mughal empire's period of greatest prosperity, was grief-stricken when his third wife, Mumtaz Mahal, died during the birth of their 14th child, Gauhara Begum. Construction of the Taj Mahal began in 1632. The court chronicles of Shah Jahan's grief illustrate the love story traditionally held as an inspiration for Taj Mahal.The principal mausoleum was completed in 1648 and the surrounding buildings and garden were finished five years later. Emperor Shah Jahan himself described the Taj in these words:

1. The Moonlight Garden to the north of the Yamuna.
2. Terrace area: Tomb, Mosque and Jawab.
3. Charbagh (gardens).
4. Gateway, attendant accommodations, and other tombs.
5. Taj Ganji (bazaar)
Should guilty seek asylum here,
Like one pardoned, he becomes free from sin.
Should a sinner make his way to this mansion,
All his past sins are to be washed away.
The sight of this mansion creates sorrowing sighs;
And the sun and the moon shed tears from their eyes.
In this world this edifice has been made;
To display thereby the creator's glory.
The Taj Mahal incorporates and expands on design traditions of Persian architecture and earlier Mughal architecture. Specific inspiration came from successful Timurid and Mughal buildings including; the Gur-e Amir (the tomb of Timur, progenitor of the Mughal dynasty, in Samarkand), Humayun's Tomb, Itmad-Ud-Daulah's Tomb (sometimes called the Baby Taj), and Shah Jahan's own Jama Masjid in Delhi. While earlier Mughal buildings were primarily constructed of red sandstone, Shah Jahan promoted the use of white marble inlaid with semi-precious stones, and buildings under his patronage reached new levels of refinement.
