The Patiala and East Punjab States Union (PEPSU) was a state of India uniting eight princely states between 1948 and 1956. The state covered an area of 26,208 km². Shimla, Kasauli, Kandaghat, Dharampur and Chail also became part of the PEPSU. On 1 November 1956, PEPSU was merged mostly into Punjab State following the States Reorganisation Act. A part of the former state of PEPSU, including the sou
th-eastern portion around Jind and the Narnaul enclave, presently lie within the state of Haryana, which was separated from Punjab on 1 November 1966. Some other areas that belonged to PEPSU, notably Solan and Nalagarh, now lie in the state of Himachal Pradesh.
