of Bengal". Chaitanya Mahaprabhu was born in Nabadwip. One of the Indian schools of logic (Tarka sastra) called Navya Nyaya system was developed in Nabadwip, which produced great logicians in the 15th century. Nabadwip was an important seat of political power and the capital of Bengal under Ballal Sen and later Lakshman Sen, kings of the Sena Empire, who ruled from 1159 to 1206. In 1202, Nabadwip was captured by Bakhtiyar Khilji. This victory paved the way for Muslim rule in Bengal. The British defeated Siraj ud-Daulah, Nawab of Bengal, at Palashi in this district. The 1859 revolt against European Indigo planters started from the village of Chaugacha in Krishnanagar, Nadia. Nadia is thought to have had trade relations with Tibet, Nepal and Bhutan. Pre-independence Nadia had five subdivisions: Krishnagar sadar, Ranaghat, Kushtia, Meherpur and Chuadanga. Due to some cartographic error in 1947, large part of Nadia except Nabadwip initially were included into East Pakistan (now Bangladesh). Due to protests rectification was made and on the night of August 17, 1947, Ranaghat, Krishnanagar, Shikarpur in Karimpur and Plassey were placed in India. Since then some parts of this district have been celebrating Independence day on August 17 and August 18.
