In 1912, the province of Bihar and Orissa was detached from Bengal, and the Orissa Tributary States were under the authority of the governor of Bihar and Orissa. In 1936 Orissa became a separate province, but the Orissa Tributary States were merged into the Eastern States Agency, which was under the direct authority of the Governor-General of India rather than that of the provincial governor. After the Indian independence in 1947, the rulers of the states acceded to the Government of India. They established the Eastern States Union in the same year. Their aim was to establish a unit that would be large enough to exist as a separate state within the Indian Union. But the union failed and the former Orissa Tributary States, except the Oriya speaking princely states of Saraikela and Kharsawan, were integrated into the state of Orissa.
