Dhirubhai Ambani started in yarn trading in Bombay in 1957, buying polyester yarn from manufacturers and selling it to weavers. The insight was not the textile business — it was how to use capital markets, regulatory relationships, and vertical integration simultaneously to build a company that competitors could not easily threaten. The 1977 IPO of Reliance Textile Industries turned thousands of small investors into shareholders in a moment when Indian equity markets were shallow and public offerings were rare. Those shareholders became vocal constituencies for the company's continued expansion.
The move into petrochemicals in 1980 was backward integration into the feedstock supply chain, not diversification. Dhirubhai needed raw materials for the textile operation; rather than buying them from third parties at market prices, he built the production capacity himself. The Hazira plant commissioned in 1991 and the Jamnagar refinery commissioned in 2000 followed the same logic at progressively larger scale — each capital investment reduced dependence on external suppliers while creating new revenue streams.
Mukesh Ambani inherited the company after Dhirubhai's death in 2002 and a complex sibling dispute with Anil Ambani that was settled in 2005 through a corporate split. The demerger created two separate companies: Mukesh retained the core energy and chemicals business that became the foundation for everything that followed, including the Jio telecom entry that redefined Indian connectivity.
Dhirubhai Ambani founded Reliance in 1966 and turned a textile trading operation into an integrated industrial group. His specific contribution was the Reliance operating pattern: enter a constrained market, control more of the value chain, build scale, brand the output, and finance expansion through a wide base of investors. Vimal textiles gave the company a consumer-facing identity, while petrochemicals and polyester integration gave it manufacturing depth. He made equity ownership feel accessible to Indian households and turned shareholder meetings into confidence-building events. Ambani died in 2002, but his influence remains visible in Reliance's appetite for large projects, public-market communication, vertical integration, and willingness to challenge entrenched incumbents with aggressive scale.
Mukesh Ambani was not the original founder, but he is listed here because his role in building modern Reliance is foundational to the company readers see today. After Dhirubhai Ambani's death in 2002 and the 2005 family split, he led the core Reliance Industries business through refining expansion, organized retail, telecom, digital platforms, media, and new energy. His most consequential decision was Jio's 2016 launch, which used years of spectrum and network investment to change Indian telecom pricing. He also executed the 2020 Jio Platforms stake sales that reduced debt and brought in Meta and Google. His lasting influence is the belief that Reliance can use capital-heavy infrastructure to reshape consumer markets.

Reliance Industries Limited traces its origin to 1966, when Dhirubhai Hirachand Ambani, a Gujarati from a modest Junagadh family who had worked as a clerk in Aden (Yemen) for an oil trading company, established Reliance Commercial Corporation in Mumbai with a focus on importing polyester yarn from Japan and exporting Indian spices and textile fibers to overseas markets. Born in 1932, Dhirubhai had returned to India in 1958 with limited capital and significant ambition, having developed an understanding of international commodity trading through his Aden years and an instinct for the regulatory arbitrage opportunities available within India's License Raj economy. The trading business evolved into manufacturing as Dhirubhai recognized that the higher-margin opportunity lay in producing polyester rather than importing it, and the company established its first synthetic textile mill in Naroda, Gujarat, in 1966-1968 under the Vimal brand. The Vimal brand became one of India's leading fabric brands through the 1970s, supported by aggressive marketing including the famous 'Only Vimal' advertising campaigns featuring Bollywood celebrities. The polyester manufacturing success provided the operating cash flow that funded vertical integration into petrochemicals, refining, and ultimately the diversified conglomerate that Reliance Industries is today. Dhirubhai's founding story — modest origins, trading-to-manufacturing transition, aggressive use of regulatory arbitrage — has become foundational mythology in Indian business history.
Reliance Textile Industries (renamed Reliance Industries in 1985) completed its initial public offering on the Bombay Stock Exchange in 1977, an event widely credited with pioneering Indian retail equity culture and bringing millions of middle-class Indians into stock ownership for the first time. The IPO raised approximately Rs 28 lakh (a modest amount in nominal terms but significant in 1977 Indian context) at a face value of Rs 10 per share, and Dhirubhai Ambani and his team aggressively marketed the offering to retail investors across India through bank branches, postal outlets, and direct retail outreach, recruiting hundreds of thousands of individual investors at a time when Indian retail share ownership was negligible. The shareholder count grew rapidly through the 1980s as Reliance issued multiple follow-on offerings, bonus shares, and rights issues, and by the mid-1980s Reliance had reportedly the largest individual shareholder base of any Indian company with millions of retail investors. The annual general meetings became massive public events held in sports stadiums to accommodate the shareholder turnout. The strategic significance extended beyond Reliance — the company's pioneering of retail equity culture established the template for subsequent Indian companies and contributed materially to the development of Indian equity markets. The shareholders who held Reliance shares from the 1977 IPO through the subsequent five decades earned returns measured in tens of thousands of percent, with the original Rs 10 face value shares having multiplied dramatically through bonus issues and price appreciation.
The 2005 split of the Reliance Group between brothers Mukesh and Anil Ambani, following the death of their father Dhirubhai Ambani in July 2002 without a clear succession plan, was one of the largest and most public family business divisions in global corporate history. After three years of escalating conflict between the brothers managed publicly and through Indian regulatory and political channels, their mother Kokilaben Ambani brokered a settlement in June 2005 that divided the family business empire into two distinct groups. Mukesh Ambani, the elder brother, received the petrochemicals, refining, oil and gas exploration, textile, and emerging telecommunications-and-retail businesses through Reliance Industries Limited (which retained the Reliance name and the parent-company structure). Anil Ambani, the younger brother, received the telecommunications (Reliance Communications), financial services (Reliance Capital, Reliance Mutual Fund), power generation (Reliance Power, Reliance Infrastructure), and entertainment businesses through the Reliance Anil Dhirubhai Ambani Group (ADAG). The split was structured through share swaps and asset transfers and was largely completed by 2006. The subsequent trajectories of the two groups have diverged dramatically — Mukesh's Reliance Industries has grown to become India's largest company by market capitalization, while Anil's businesses collapsed through the 2010s and by 2019 Reliance Communications had filed for bankruptcy and the broader Anil Ambani group was substantially dismantled.
The Jamnagar refinery complex in Gujarat is the world's largest oil refining facility by capacity, with combined nameplate capacity of approximately 1.4 million barrels per day across two integrated refinery units that Reliance Industries built between 1996 and 2008. The original Jamnagar refinery (Phase 1) was commissioned in 1999 with capacity of approximately 660,000 barrels per day, making it among the largest single refineries in the world at the time and demonstrating Reliance's ability to execute major capital projects on schedule and on budget — a capability that distinguished the company from Indian peers and many global integrated oil companies. The Special Economic Zone (SEZ) refinery (Phase 2), commissioned in 2008 with capacity of approximately 580,000 barrels per day, was designed specifically to process heavy and sour crude oil that traded at a significant discount to lighter crude grades, capturing the refining-margin advantage from the price differential. The combined complex processes approximately 1.4 million barrels per day across the two units and is among the most complex refineries in the world, with extensive secondary processing capacity that produces a high yield of high-margin products including gasoline, diesel, jet fuel, and petrochemical feedstocks. The Jamnagar complex provides Reliance with substantial cash flow that has funded the diversification into telecommunications (Jio), retail, and the announced $75 billion green energy investment program. The refinery is also strategically significant as one of the largest single export sources of refined products globally.
The September 2016 launch of Reliance Jio Infocomm, the 4G mobile telecommunications operator, was the most disruptive commercial event in Indian telecommunications history and one of the most consequential launches in global telecommunications. Jio entered the Indian wireless market with a launch strategy designed to break the incumbent oligopoly by offering free voice calling and 4G data for an extended introductory period, combined with the JioPhone 4G feature phone available for Rs 1,500 (approximately $20) and free voice services for life. The pricing was below the cash cost of competing operators, and Jio's launch acquired approximately 100 million subscribers within the first six months — the fastest customer-acquisition pace in telecommunications history. The competitive consequences cascaded through the Indian wireless industry over the subsequent three years. Bharti Airtel and Vodafone-Idea (formed through a 2018 merger of the two weaker incumbents) faced massive revenue and EBITDA compression as customer ARPU collapsed and capital expenditure requirements rose to match Jio's 4G coverage. Smaller operators including Reliance Communications (controlled by Anil Ambani's group separate from Jio), Aircel, and others exited the industry through bankruptcy or asset sales. By 2024 Jio had reached approximately 470 million subscribers, the largest telecom operator in India and one of the largest globally, with continued growth driven by 4G coverage expansion, 5G rollout, JioFiber wireline service, and the broader Jio Platforms digital services portfolio.
