Sivakasi is a city in Virudhunagar District in the Indian state of Tamil Nadu. The city is known for firecrackers and match factories that produce 70% of the country's produce.

The industries in Sivakasi employ over 25,000 people and the estimated turnover of the firecracker, match making and printing industries in the city is around ₹20 billion (US$240 million). The major issues in the city are the frequent accidents in the firecracker factories and the high level of child labour.

Sivakasi was established in the 15th century during the reign of the Pandya king Harikesari Parakkirama Pandian. The city was a part of Madurai and has been ruled at various times by Later Pandyas, Vijayanagar Empire, Madurai Nayaks, Chanda Sahib, Carnatic kingdom and the British. A major riot during the British Raj took place in 1899.

Sivakasi has a dry weather, making it suitable for dry crops like cotton, chillies and millets. Badhrkali Amman temple is the most prominent landmark of Sivakasi, and the temple festivals constitute the major festivals of the city. AJ and Hatsun Indoor Stadium has a coaching center for badminton and is the major sporting venue of the city.

As of 2021, Sivakasi has an estimated population of 160,047.

Sivakasi was established during the early 15th century CE. Between 1428 and 1460, a Pandya king Harikesari Parakkirama Pandian ruled the southern part of Madurai region (comprising modern-day Sivakasi and its surroundings). Hindu legend relates that he wanted to construct a temple for the Hindu god Shiva at Tenkasi and went to Kasi to bring a lingam (an iconic representation of Shiva). While returning to his palace with the prized lingam, he rested under the grove of a vilva tree, the favourite tree of Shiva. When a cow carrying the lingam refused to move from the spot, the king realised that the wishes of Shiva were different from his own, and he placed the lingam in the place where the cow halted. The place where the "Shiva lingam brought from Kasi" was installed came to be known as Sivakasi. Sivakasi was a part of the Madurai region during the 16th century. Madurai became independent from the Vijayanagar Empire in 1559 under the Nayaks. Nayak rule ended in 1736 and Madurai was repeatedly captured several times by Chanda Sahib (1740–1754), Arcot Nawab and Muhammed Yusuf Khan (1725–1764) in the middle of the 18th century. In 1801, Madurai came under the direct control of the British East India Company and was annexed to the Madras Presidency.

The mutual confrontation between the Maravars and Nadars reached its peak in 1899, leading to a series of riots which became known as the Sivakasi riots. A total of 22 people were killed, as many as 800 houses and the Big Chariot in the center of the city (used by the temple during festivals) were burnt during the riots. Eventually, the riots came to an end after the intervention of the military in mid-July 1899.

The Sivakasi municipality was established in 1920. After India's independence from the British in 1947, Sivakasi continued to be a municipality under the Madras state and later a part of Tamil Nadu, when the state was split on linguistic lines during 1953, 1956 and 1960 and renamed in 1968. It was promoted to a second-grade municipality in 1978, first-grade in 1978, selection-grade in 1998, special-grade in 2013 and proposed to be upgraded as municipal corporation in 2017. On 31-December-2020, both Sivakasi and Thiruthangal are merged with a view to promote Sivakasi as municipal corporation. It is declared as Municipal Corporation on 24-August-2021 in Tamil Nadu legislative assembly. Over the decades after independence, Sivakasi grew as an industrial city specialising in firecracker, match and printing industries. Several incidents of fire and explosions have occurred in the fireworks factories.

The economy of Sivakasi is dependent on three major industries: firecrackers, matchbox manufacturing, and printing. The city has 520 registered printing industries, 53 match factories, 32 chemical factories, seven soda factories, four flour mills and two rice and oil mills. The city is the nodal center for firecracker manufacturing at the national level. In 2020 there are around 1070 registered firecracker manufacturing companies in sivakasi and 8 lakh (800,000) people were directly and indirectly employed by the industry. Some of the private enterprises had an annual turnover of ₹5 billion (US$60 million). In 2011, the combined estimated turnover of the firecracker, matchbox making and printing industry in the city was around ₹20 billion (US$240 million). Approximately 70% of the firecrackers and matches produced in India are from Sivakasi. The hot and dry climate of the city is conducive to the firecracker and matchbox making industries. The raw materials for these industries were procured from Sattur earlier but were discontinued due to the high power and production cost. The source of raw materials is Kerala and Andaman. The paper for the printing industry is procured from various states. The city is a major producer of diaries, contributing to 30% of the total diaries produced in India. Printing industry in the city was initially utilized for printing labels for the firecrackers and later evolved with modern machinery to grow as a printing hub. In 2012, all the industries suffered 15–20% production loss due to power shortage and escalating labor cost.

The major issues in the fireworks industry in Sivakasi is child labour and frequent accidents. In a blast in 1991 in a factory, 39 people were killed and 65 others were injured. In July 2009, more than 40 people were killed in a fire accident in a firecracker unit. The police traced out unregistered units and irregularities that led to the accident. In a fire accident in August 2011, seven people were killed and five were seriously injured. A similar fire accident and blast in a private unit in September 2012 killed 40 people and injured 38 others. The common reasons cited for the accidents are inadequate training of workers and supervisors involved in different stages of production and marketing of firecracker items. Other reasons are found to be overstocking of explosives, raw material and finished goods, and employment of workers in excess of the permitted strength.

Child labour in the industries, especially in matchbox making factories, was at its peak during the 1970s and 1980s. In 1981, the child workforce in the age group 4–16 was 30% of the total workforce, 90% of whom were girls. In 1986, the National Child Labour project estimated child labour in Sivakasi matchbox making industries to be 14,121 children. The estimates indicated 80% of the child labour belonging to Scheduled Castes (SC), who were marginalised for centuries for cheap labour. Poverty and lack of farm produce were stated as the main reason for child labour. The employers also preferred children because of ease of management, discipline, and lack of labour unions. The children in these industries suffered from a backache, neckache, tuberculosis, malnutrition, gastrointestinal disorders, dermatitis, respiratory disorders, over-exhaustion, burn injuries and water-borne diseases due to exposure to harmful chemicals in the work environment. The situation of the child labour came to light during an accident of a bus transporting the children in 1976. The central government appointed a one-man committee under Harbans Singh in 1978, who reported abolishing child labour would seriously impact the economy of the region. The National Policy on child labour was formulated by the central government in August 1987, aiming at the rehabilitation of children withdrawn from these factories. In 1988, the union labour ministry initiated a programme for providing informal education, free healthcare and free lunch for children working in the factories. The Supreme Court of India, in a judgement, ruled in December 1996 indicating provisions for preventing child labour like compensation for the child employed, employment to the adult members of the family and contribution to the corpus fund by the state government. From the establishment of child labour Act in 1986 till 2011, 150,000 inspections on child labour have been conducted in the factories, 1,500 cases have been registered and few prosecutions have been made. The results indicated a small amount of child labour in the cottage and household industries.
