Agra (; ) is a city on the banks of the Yamuna river in the Indian state of Uttar Pradesh, about south-east of the national capital Delhi and 330 km west of the state capital Lucknow. It is also the part of Braj region. With a population of roughly 1.6 million, Agra is the fourth-most populous city in Uttar Pradesh and twenty-third most populous city in India.

Agra's notable historical period began during Sikandar Khan Lodi's reign, but the golden age of the city began with the Mughals in the early 16th century. Agra was the foremost city of the Indian subcontinent and the capital of the Mughal Empire under Mughal emperors Babur, Humayun, Akbar, Jahangir and Shah Jahan. Under Mughal rule, Agra became a centre for learning, arts, commerce, and religion, and saw the construction of the Agra Fort, Sikandra and Agra's most prized monument, the Taj Mahal, constructed between 1632 and 1648 by Shah Jahan in remembrance of his wife Mumtaz Mahal. With the decline of the Mughal empire in the late 18th century, the city fell first to Marathas and later to the East India Company. After Independence, Agra has developed into an industrial town, with a booming tourism industry, along with footwear, leather and other manufacturing. The Taj Mahal and the Agra Fort are UNESCO World Heritage Sites. The city features mild winters, hot and dry summers and a monsoon season, and is famous for its Mughlai cuisine. Agra is part of the Golden Triangle tourist circuit, along with Delhi and Jaipur; and the Uttar Pradesh Heritage Arc, a tourist circuit of Uttar Pradesh, along with Lucknow and Varanasi.

== Name ==<!--This entire subsection is fully referenced and relatively high quality. Other sections should follow suit.-->

There are several proposed derivations for the name Agra, none of which is very satisfactory. The most accepted etymon is the Hindi word agar (salt pan), a name given to it due to the region's brackish soil; salt was once made in the area by evaporation. Others derive it from Hindu mythology, claiming that the Sanskrit word agra () (literally 'front') means in this case the first of the many small forests where Krishna frolicked with the gopis of Vrindavan. The term Agravana hence means grove forest.

Pre-Mughal era

Agra has two histories: one of the ancient city on the east, or left, bank of the river Yamuna, going back so far as to be lost in the legends of Krishna and Mahabharata and reestablished by Sikandar Khan Lodi in 1504–1505; the other of the modern city, founded by Akbar in 1558, on the right bank of the river which is associated with the Mughals, and known throughout the world as the city of the Taj. Of ancient Agra little now remains except few traces of the foundations. It was a place of importance under various Hindu dynasties previous to the Muslim invasions of India, but its history is unclear, and possess little historical interest. The 17th century chronicler named Abdullah said it was a village before the reign of Sikandar Lodi. The king of Mathura had used the Agra fort as a jail. The degradation in the status of the site was a result of the destruction brought upon it by Mahmud of Ghazni. Masud Sa'd Salman claims to have been there when Mahmud assaulted Agra, claiming the Raja Japal surrendered after seeing a nightmare. Mahmud however proceeds to pillage the city.

Agra's period of historical importance began during Sikandar Lodi's reign. In 1504–1505, Sultan Sikandar Lodi (reigned 1489–1517), the Afghan ruler of the Delhi Sultanate, rebuilt Agra and made it the seat of government. Sikandar Lodi appointed a commission which inspected and surveyed both sides of the Yamuna from Delhi to Etawah and finally chose a place on the left bank, or the east side of the Yamuna, as the site for the city. Agra on the left bank of the Yamuna grew into a large flourishing town with royal presence, officials, merchants, scholars, theologians and artists. The city became one of the most important centres of Islamic learning in India. The sultan founded the village of Sikandra in the northern suburbs of the city and built there a Baradari of red sandstone in 1495, which was converted into a tomb by Jahangir, and now stands as the Tomb of Mariam-uz-Zamani, Akbar's empress.

After the Sultan's death in 1517, the city passed on to his son, Sultan Ibrahim Lodi (reigned 1517–26

Mughal era

The golden age of the city began with the Mughals. Agra was the foremost city of the subcontinent and the capital of the Mughal Empire until 1658, when Aurangzeb shifted the entire court to Delhi.), the founder of the Mughal dynasty, acquired Agra after defeating the Lodis and the Tomaras of Gwalior in the First Battle of Panipat in 1526. Babur went on to lay out the first formal Mughal garden in India, the Aram Bagh (or Garden of Relaxation) on the banks of the river Yamuna. Babur was determined to establish the seat of his government at Agra, but was almost dissuaded by the desolate appearance of the region, as clear from this quote from his memoir Baburnama: Babur was followed by his son Humayun (reigned 1530–40 and 1555–56 Before his death, Agra had become probably one of the biggest cities in the east, with huge amounts of trade and commerce happening through its bazaars. The English traveller Ralph Fitch who visited Agra in September 1585 in the life-time of Akbar, writes about the town: Akbar's mausoleum at Sikandra was completed during Jahangir's reign. The Jahangiri Mahal in Agra fort and the tomb of Itmad-ud-daulah were also constructed during the reign of Jahangir. Jahangir loved Lahore and Kashmir more than Agra, but the latter continued to be the first city of the realm.

Shah Jahan later shifted the capital to Shahjahanabad (now known as Delhi) in the year 1648, followed by his son Aurangzeb (reigned 1658–1707 The Jats under Maharaja Suraj Mal conquered Agra on 12 June 1761, after a month-long siege culminating in the Mughals surrendering to the Jat army. After this victory, the Jats melted the silver doors of the Taj Mahal. Agra remained under Jat control until 1774, when the Mughal Commander Mirza Najaf Khan recaptured it. 11 years after the Mughals reclaimed Agra, the city was conquered in 1785 by another post-Mughal Empire power, the Marathas, before falling into the hands of the British East India Company in 1803 after the Second Anglo-Maratha War. In the years 1834–1836, Agra was the capital of the short-lived Presidency of Agra, administered by a Governor. It was then the capital of the North-Western Province from 1836 to 1858, governed by a Lieutenant-Governor. Agra was one of the centres of the Indian rebellion of 1857.

During the Indian rebellion of 1857, when East India Company rule across many parts of India was threatened, the news of the mutiny at Meerut reached Agra on 14 May. On 30 May some companies of the 44th and 67th Native Infantry sent to Mathura to bring in the treasury mutinied and carried off the treasury to the rebels in Delhi. With the fear of the rebellion spreading to Agra as well, the rest of these native infantry battalions, which were part of the garrison at Agra, were successfully disarmed by the British on 31 May. However, when the Gwalior contingent mutinied on 15 June, all other native units followed. On 2 July the rebel force of the Nimach and Nasirabad contingents reached Fatehpur Sikri. Fearing advance of the mutineers to Agra, some 6000 Europeans and associated people moved into the Agra Fort for safety on 3 July. On 5 July, the British force stationed there attempted to attack an approaching force of Mutineers, but was defeated, and the British retreated back into the fort. The capital of the North Western Provinces was shifted from Agra to Allahabad in 1858. Gradually, Agra declined to the position of a mere provincial town, and its prosperity declined: However, in the years between the mutiny and independence Agra was a major centre of Hindi and Urdu journalism. Paliwal park(formerly Hewitt park) in Agra is named after S.K.D Paliwal, who brought out the Hindi daily Sainik.

Post Independence and Mughal legacy

Post India's independence, Agra has been a part of Uttar Pradesh and has gradually developed into an industrial city, with a significant contribution to Uttar Pradesh's economy. The city is now a popular tourist destination and hosts tourists from across the world. The Taj Mahal and Agra Fort received UNESCO World Heritage Sites status in 1983. The Taj Mahal witnesses tourists, photographers, historians and archaeologists in massive numbers all around the year. The Taj Mahal has become a symbol of India. Post Independence, Taj Mahal has been visited by world leaders like US Presidents Dwight D. Eisenhower (1959), Bill Clinton (2000), and Donald Trump (2020). Queen Elizabeth II of the United Kingdom had visited Taj Mahal in 1961 on her India visit. Taj Mahal has also been visited by Russian President Vladimir Putin (1999), Chinese President Hu Jintao (2006), Israeli Prime Minister Benjamin Netanyahu (2018) and Canadian Prime Minister Justin Trudeau (2018). Agra is the birthplace of the now extinct religion known as Din-i-Ilahi, which was founded by Akbar and also of the Radhaswami Faith, which has around two million followers worldwide. Agra is included on both the Golden Triangle tourist circuit, along with Delhi and Jaipur, as well as the Uttar Pradesh Heritage Arc, a tourist circuit of Uttar Pradesh, along with Lucknow and Varanasi.

Geography and climate

Geography<!--This entire subsection is fully referenced and relatively high quality. Other sections should follow suit.-->

The region around Agra consists almost entirely of a level plain, with hills in the extreme southwest. The rivers in the region include Yamuna and Chambal. The region is also watered by the Agra Canal. Millet, barley, wheat, and cotton are among the crops grown in the surrounding countryside. Both Rabi and Kharif crops are cultivated. The deserted city of Fatehpur Sikri is about 40&nbsp;km southwest of Agra. The sandstone hills near Fatehpur Sikri and on the south-eastern borders of the district are offshoots from the Vindhya range of Central India. Agra is about 210&nbsp;km away from the National capital of New Delhi (via Yamuna Expressway), about 336&nbsp;km from state capital Lucknow (via Agra-Lucknow Expressway), and about 227&nbsp;km from Kanpur (via Agra-Lucknow Expressway). The city has an average elevation of 170 metres above sea level. This is the tropical and subtropical steppe climate, a major climate type of the Köppen classification that occurs primarily on the periphery of the true deserts in low-latitude regions, forming a transition between the desert climate (BW), and the more humid subtropical and tropical climates.

The city features warm winters, sweltering and dry summers and a monsoon season. The Agra district, from its proximity to the sandy Thar Desert to the west, is relatively dry, and has greater extremes of temperature than districts further east. The hot west wind, Loo blows mainly during April, May, and June with great force and can cause fatal heatstrokes. The highest temperature ever registered in Agra was 48.6&nbsp;°C, on 28 May 2024. The monsoon rains usually begin in the first week in July; and generally end in mid-September. However, the monsoons, though substantial in Agra, are not quite as heavy as the monsoon in other parts of India. The weather moderates by the middle of October. The region around Agra, the northwest Indo-Gangetic plain is prone to extreme fog in the winter months, which is caused due to natural factors like low winds, low temperatures, availability of moisture apart from air pollution. This phenomenon often leads to big delays and sometimes cancellation of trains due to poor visibility. Agra has high levels of air pollution and one of the worst AQIs in India. In a study conducted by WHO using data from years 2010–2016, Agra ranked as the 8th most polluted city in India, along with other nearby cities including Delhi, Kanpur and Faridabad.

Environment

The Taj Mahal has faced significant damage due to air pollution and sewage discharge into the nearby Yamuna river. The white-marble Taj Mahal is turning yellow and green because of filthy air in the world's eighth-most polluted city. The Taj Mahal flanks the garbage-strewn Yamuna river and is often enveloped by dust and smog from smokestacks and vehicles.

The Yamuna River is one of the most polluted rivers in the world. Agra is the second largest contributor to River Yamuna's pollution, after Delhi. The river's pollution has caused several problems for the Taj Mahal such as 'Attacks by Bugs and their Green Slime', foul stench and corrosion of Taj Mahal's foundation. Activists say that the Yamuna river bed between Itmad-ud-Daula and the Taj Mahal has become a dumping ground for pollutants. Polythene, plastic waste, leather cuttings from shoe factories, construction material, are all thrown into the river. The only major wildlife sanctuary near Agra is Keetham Lake, also known as Sur Sarovar Bird Sanctuary. The lake has nearly two dozen varieties of migratory and resident birds.<!-- Keetham lake info soon --><!-- Yamuna pollution statistics soon --><!-- Escape of wild animals in city soon --><!-- Groundwater depletion soon --><!-- Possibly shift air pollution part here --><!-- TTZ very imp info soon -->
