Bengali literature (Bangla Sahityô) denotes the body of writings in the Bengali language and which covers Old Bengali, Middle- Bengali and Modern Bengali with the changes through the passage of time and dynastic patronization or non-patronization. Bengali has developed over the course of roughly 1,300 years. If the emergence of the Bengali literature supposes to date back to roughly 650 AD, the development of Bengali literature claims to have 1,600 years of old. The earliest extant work in Bengali literature is the Charyapada, a collection of Buddhist mystic songs in Old Bengali dating back to the 10th and 11th centuries. The timeline of Bengali literature is divided into three periods: ancient (650–1200), medieval (1200–1800) and modern (after 1800). Medieval Bengali literature consists of various poetic genres, including Hindu religious scriptures (e.g. Mangalkavya), Islamic epics (e.g. works of Syed Sultan and Abdul Hakim), Vaishnava texts (e.g. biographies of Chaitanya Mahaprabhu), translations of Arabic, Persian and Sanskrit texts, and secular texts by Muslim poets (e.g. works of Alaol). Novels were introduced in the mid-19th century. Nobel laureate Rabindranath Tagore is the best known figure of Bengali literature to the world. Kazi Nazrul Islam, notable for his activism and anti-British literature, was described as the Rebel Poet and is now recognised as the National poet of Bangladesh.
The first works in Bengali appeared between 10th and 12th centuries C.E. It is generally known as the Charyapada and are 47 mystic hymns composed by various Buddhist monks, namely; Luipada, Kanhapada, Kukkuripada, Chatilpada, Bhusukupada, Kamlipada, Dhendhanpada, Shantipada and Shabarapada amongst others. The manuscript was discovered on a palm leaf in the Nepal Royal Court Library in 1907 by the Bengali linguist Haraprasad Shastri. Due to the language of these manuscripts only being partially understood, they were classified by Shastri with the name Sandhya Bhasha (সন্ধ্যা ভাষা), meaning dusk language.
