Ghazipur is well known for its opium factory, established by the British East India Company in 1820 and still the biggest legal opium factory in the world, producing the drug for the global pharmaceutical industry. Ghazipur lies close to the Uttar Pradesh-Bihar border, about east of Varanasi. As per the verbal and folk history. Ghazipur was covered with dense forest during the Vedic era and it was a place for ashrams of saints during that period. The place is related to the Ramayana period. Maharshi Jamadagni, the father of Maharshi Parashurama, is said to have resided here. The famous Gautama Maharishi and Chyavana were given teaching and sermon here in ancient period. Lord Buddha gave his first sermon in Sarnath, which is not far from here. However some sources state that the original name was Gadhipur which was renamed around 1330 after Ghazi Malik. A 30 ft. high Ashoka Pillar is situated in Latiya, a village 30 km away from the city near Zamania Tehsil is a symbol of Mauryan Empire. It was declared a monument of national importance and protected by the archeological survey of India. In the report of tours in that area of 1871–72 Sir Alexander Cunningham wrote, "The village receives its name from a stone lat, or monolith". The first Scientific Society of India was established first in Ghazipur in 1862 by Sir Syed Ahmed Khan for propagating modern Western knowledge of science, technology and industry. It was a departure from the past in the sense that education made a paradigm shift from traditional humanities and related disciplines to the new field of science and agriculture. Some current institution like Technical Education and Research Institute (TERI), part of post-graduate college PG College Ghazipur, in the city, takes their inspiration from that first Society.
