Howrah or Haora (In past known as Haura) (Bengali: হাওড়া) is an well-known industrial city in the world, The name came from the word Haor Bengali word for a fluvial swampy lake, which is sedimentologically a depression where water, mud and organic debris accumulate. The word itself was rather used in eastern part of Bengal (now Bangladesh), as compared to the western part (now West Bengal). The district located on the west bank of the Hoogli River opposite of Kolkata. Howrah is located at 22.59°N 88.31°E. It has an average elevation of 12 meters (39 feet).

The history of the city of Howrah dates back over 500 years, but the district is situated in an area historically occupied by ancient Bengali kingdom of Bhurshut. Venetian explorer Cesare Federici, who travelled in India during 1565–79, mentioned a place called Buttor in his journal circa 1578. As per his description, this was the location into which large ships could travel (presumably the Hoogli River) and perhaps a commercial port. This place is identifiable with the modern day neighbourhood of Bator. Bator was also mentioned in the Bengali poetry Manasamangal written by Bipradas Pipilai in 1495.

In 1713, the Bengal Council of the British East India Company, on the accession of the Emperor Farrukhsiyar, grandson of Aurangzeb, to the throne of Delhi, sent a deputation to him with a petition for a settlement of five villages on west bank of Hooghly river along with thirty-three villages on the east bank. The list of villages appeared in the Consultation Book of the Council dated 4 May 1714. The five villages on the west bank on Hooghly river were: 'Salica' (Salkia), 'Harirah' (Howrah), 'Cassundeah' (Kasundia), 'Ramkrishnopoor' (Ramkrishnapur), and 'Battar' (Bator): all identifiable with localities of modern day Howrah city. The deputation was successful except for these five villages. By 1728, most of the present day Howrah district was part of either of the two zamindaris: Burdwan or Muhammand Aminpur. After Battle of Plassey, as per the treaty signed with the Nawab of Bengal, Mir Qasim, on 11 October 1760, Howrah district (then part of Burdwan) came under control of East India Company. In 1787, the Hooghly district was formed, and till 1819, the whole of the present day Howrah district was added to it. The Howrah district was separated from the Hooghly district in 1843.

With the establishment of the Howrah Railway Station in 1854 started the most important phase of its industrial development. Flour mills were established in 1855, followed by Jute mills and around the 1870s, there were five mills near Howrah station. The Howrah–Shalimar Railway Section and the Shalimar Terminus were constructed in 1883.

By 1914 almost every major city in India was served by the Railways and the increased demand for its rolling stocks and repair works resulted in the establishment of railway workshop in Liluah of Howrah. The light engineering industry grew up after 1914 at Dasnagar of Belegacha (Belgachia). This industrial boom continued throughout the Second World War and brought with it rapid urbanization phase in unplanned manner creating slums near the industrial establishments.

There are one municipal corporation, one Municipality and sixty seven gram panchayet in the district. It is the second largest city of West Bengal. The headquarters of the district situated near Howrah Maidan, and that is also Howrah Sadar Sub divisional headquarters of the district.  It is a twin city to Kolkata.
