Rajasthan (Rajputana State) is the result of a long process of political unification initiated in 1948. The process of integration that started from 17th March 1948 lasted till 1 November 1956. The State was formed as a result of merger of the erstwhile 19 princely states and 2 chiefships on 30th March 1949. The administration of Covenanting States was taken over by the new State on 7th April 1949. Later on Matsya was also integrated in Rajasthan on 15th May 1949. The State took a new shape on 1st November 1956 under the States Reorganization Act, 1956 (Act No. 37 of 1956).
Consequent upon the emergence of the State of Rajasthan in the year 1949, the foremost task which came up before administration was to introduce a unified administrative system in the new State. This task was completed in various stages, viz., formation of committees to formulate proposals for integrated set up of each department, appointment of personnel on ad hoc basis in the integrated set up pending final selection, making of rules for selection of personnel for permanent absorption in various services and integrated set up of departments. The principles and procedures to be observed in carrying on this programme were laid down in notification dated the 28th May 1949 for the guidance of various departmental reorganization committees constituted to submit proposals to the Integration Department. The process of re-organizing the services and of fitting Government Servants of the Covenanting States into different services and cadres was expedited. The recommendations of these committees were further examined by the Integration Department and orders were issued for the integrated set up of each department during the period from September 1949 to June 1950. In the second stage Government decided to review the existing strength of ministerial staff particularly to examine the possibility of reduction of staff if possible compatible with the running of departments efficiently and economically. Till the end of June, 1950, appointments to posts in integrated set up were made on ad hoc basis after examining the general suitability of officers selected for appointments to the posts. Then, substantive appointments were made in the integrated services of Rajasthan.
