The shi'ite state of Awad was established by Mir Mohammad Amin, an Iranian known as Sa'adat Khan, in the Awad region of India, in 1722. His successors regarded themselves as the agents of the Mughal Empire based in Delhi, and were called nawabs. In 1819, the British encouraged them to use the title of shah, indicating their independence. In the famous Buxar battle, nawab Shoja' ud-Dowla, the Awad ruler, trying to help Mir Qasim, the former ruler of Bengal, fought the British East India Company, which spearheaded British colonialism. His defeat led to the Benares treaty, in 1765, which provided the British with many concessions.They were allowed to have a representative at the Awad court, who had a significant role in encouraging Awad's high ranking officials to work for the British. In the early nineteenth century, the Awad state, which was very important for the Shi' a in India, became a British protectorate.Eventually, in 1857, Awad was annexed by the British, and became part of British India.
