# East Punjab

East Punjab was a state of Dominion of India and later Republic of India from 1947 until 1950. It consisted parts of the Punjab State of British India that remained in India following the partition of the state between the new dominions of Pakistan and India by the Radcliffe Commission in 1947. The mostly Muslim western parts of the old Punjab became Pakistan's West Punjab, later renamed as Punjab Province, while the mostly Hindu and Sikh eastern parts remained with India.

## History
### Partition of India

With the partition of India, the Punjab province was to be divided in two as per the Indian Independence Act 1947, passed by the parliament of the United Kingdom. The province was to cease to exist, and two new provinces were to be constituted, to be known respectively as West Punjab & East Punjab. All the princely states of the Punjab States Agency, except Bahawalpur, which acceded to the Dominion of Pakistan, acceded to the new Union of India and were combined into the Patiala and East Punjab States Union (PEPSU). The northeast Hill States of the Punjab Province banded together and were declared a union territory in 1950 as Himachal Pradesh.

### Renaming of the state

The Constitution of India, which came into effect in 1950, renamed the province of "East Punjab" as the state of "Punjab".

### Reorganisation of Indian States

In 1956, the PEPSU was merged into an expanded Punjab state.

### Punjabi Suba movement

With effect from 1 November 1966, there was yet another reorganisation, this time on linguistic lines, when the state of Punjab as constituted in 1956 was divided into three: the mostly Hindi-speaking part became the present-day Indian state of Haryana and the mostly Punjabi-speaking part became the present-day Punjab, while a new union territory (Chandigarh) was also created, to serve as a capital to both states. At the same time, some parts of the former territory of Patiala and East Punjab States Union, including Solan and Nalagarh, were transferred to Himachal Pradesh.
