Bengaluru

Bengaluru is the capital and largest city of Karnataka, a state in southern India, and serves as one of the principal centres of science, technology, manufacturing, and commerce on the subcontinent. The city sits on the Deccan Plateau at an elevation of approximately 920 metres above sea level, giving it a comparatively mild climate relative to other major Indian cities. Its official Kannada name, Bengaluru, was formally adopted by the Government of Karnataka in November 2006, replacing the anglicised form Bangalore that had been in use since the British colonial period.

History

The founding of the city is traditionally attributed to the chieftain Kempe Gowda I, who constructed a mud fort at the site in 1537 CE. The territory subsequently passed through the hands of several regional powers, including the Vijayanagara Empire, the Keladi Nayakas, and the Mughal Empire. In the late eighteenth century, Bengaluru became a key seat of power under Hyder Ali and his son Tipu Sultan, rulers of the Kingdom of Mysore, who expanded and fortified the city significantly. Following the fall of Tipu Sultan at the Fourth Anglo-Mysore War in 1799, the British East India Company ceded administrative control of the region to the Wodeyar dynasty of Mysore while retaining a military cantonment in the city. British influence shaped the layout of the cantonment area, producing a distinct urban geography that separated the older pete (market town) from the planned colonial settlement. After Indian independence in 1947, Bengaluru became the capital of the newly reorganised state of Mysore, which was renamed Karnataka in 1973.

Geography and Climate

Bengaluru occupies a broadly undulating terrain on the southern portion of the Deccan Plateau. The city is drained by several small rivers and streams, most notably the Vrishabhavathi and the Arkavathi, though rapid urbanisation has placed significant stress on these water bodies. The metropolitan area encompasses numerous lakes, historically numbering in the hundreds, though many have been encroached upon or polluted over recent decades.

The climate is classified as tropical savanna, moderated by altitude. The city experiences two principal monsoon seasons: the southwest monsoon between June and September and a shorter northeast monsoon in October and November. Temperatures generally range from around 15 °C in the coolest winter months to approximately 35 °C during the pre-monsoon summer peak, though heat events have intensified in recent years, a trend attributed by researchers to urban heat island effects and reduced green cover.

Economy

Bengaluru is the largest contributor to Karnataka's gross state domestic product and one of the most economically productive cities in India. Its economy is notably diversified, encompassing information technology, biotechnology, aerospace, defence manufacturing, machine tools, garments, and retail.

Information Technology

The city is home to a dense cluster of multinational technology corporations, Indian IT services companies, and startups, earning it the informal designation Silicon Valley of India. Major global firms including those in software services, semiconductors, and digital infrastructure maintain significant operations in Bengaluru. The development of dedicated technology parks, beginning with the establishment of Software Technology Parks of India facilities in the early 1990s, catalysed the sector's growth. Areas such as Electronic City, Whitefield, and the outer ring road corridor have become synonymous with the IT industry.

Aerospace and Defence

Bengaluru hosts the headquarters of Hindustan Aeronautics Limited (HAL), the Indian Space Research Organisation (ISRO), the Defence Research and Development Organisation laboratories, and Bharat Electronics Limited, making it a critical node in India's strategic and space industries.

Startups and Venture Capital

The city has emerged as India's leading startup ecosystem, consistently ranking among the top startup cities in Asia. A robust network of incubators, accelerators, angel investors, and venture capital firms supports early-stage ventures across fintech, health technology, agritech, and consumer internet sectors.

Demographics and Culture

Bengaluru is among the most cosmopolitan cities in India, attracting migrants from across the country and abroad. Kannada is the official language and is spoken by a significant portion of the population, alongside Tamil, Telugu, Hindi, English, and numerous other languages. The city has historically been a centre of Carnatic classical music, Yakshagana theatre, and Kannada literature. It also sustains a vibrant contemporary arts and music scene.

The city is home to several institutions of national and international repute, including the Indian Institute of Science, the National Law School of India University, and the Indian Institute of Management Bangalore, reinforcing its status as an educational and research hub.

Infrastructure and Governance

The Bruhat Bengaluru Mahanagara Palike (BBMP) functions as the primary civic authority responsible for infrastructure and municipal services. The Bengaluru Metropolitan Region Development Authority oversees planning across the wider metropolitan area. The city is served by Kempegowda International Airport, which opened in 2008 and handles tens of millions of passengers annually, making it one of the busiest airports in India. Urban mobility is supported by the Namma Metro rail network, an expanding rapid transit system with multiple operational lines and several corridors under construction as of the early 2020s. Chronic traffic congestion and water supply challenges remain significant governance concerns.
