Ancient Bengal was the site of several major janapadas. In the 2ndcentury BCE, the region was conquered by the emperor Ashoka. In the 4thcentury CE, it was absorbed into the Gupta Empire. From the 13thcentury onward, the region was ruled by several sultans, powerful Hindu states, and Baro-Bhuyan landlords, until the beginning of British rule in the 18thcentury. The British East India Company cemented their hold on the region following the Battle of Plassey in 1757, and Calcutta served for many years as the capital of British India. The early and prolonged exposure to British administration resulted in an expansion of Western education, culminating in developments in science, institutional education, and social reforms in the region, including what became known as the Bengali Renaissance. A hotbed of the Indian independence movement through the early 20thcentury, Bengal was divided during India's independence in 1947 along religious lines into two separate entities: West Bengal, a state of India, and East Bengal, a province of Pakistan which later became independent Bangladesh. Between 1977 and 2011 the state was administered by the world's longest elected Communist government.
The origin of the name Bengal (Bangla and Bongo in Bengali) is unknown. One theory suggests that the word derives from "Bang", a Dravidian tribe that settled the region around 1000BCE. The Bengali word Bongo might have been derived from the ancient kingdom of Vanga (or Banga). Although some early Sanskrit literature mentions the name Vanga, the region's early history is obscure.
In 2011 the Government of West Bengal proposed a change in the official name of the state to PaschimBanga (Bengali: পশ্চিমবঙ্গPôshchimbônggô). This is the native name of the state, literally meaning western Bengal in the native Bengali language. In August 2016 the West Bengal Legislative Assembly passed another resolution to change the name of West Bengal to "Bangla" in Hindi, "Bengal" in English, and "Bangla" in Bengali. Despite the Trinamool Congress government's efforts to forge a consensus on the name change resolution, the Indian National Congress, the Left Front, and the Bharatiya Janata Party opposed the resolution. However, the central government has turned down the proposal stating that the state should have one single name for all languages instead of three and also the name should not be the same as that of any other territory (pointing out that the name 'Bangla' may create confusion with neighboring Bangladesh).
