Why did a difference arise between Sheikh Abdullah and the central government at the beginning of the 1950s?

Pertaining to his stance on Kashmir's status

The difference between Sheikh Abdullah and the central government was related to his position on Kashmir's status.

Sheikh Abdullah assumed the role of Prime Minister in March 1948 within the State of Jammu and Kashmir. Simultaneously, India agreed to bestow provisional autonomy under Article 370. This provisional autonomy permitted the State a certain degree of self-governance. Consequently, the head of the State government came to be known as the Prime Minister.
Following his assumption of the role of Prime Minister, Sheikh Abdullah embarked on significant land reforms and implemented policies that directly benefited the common populace. However, disparities in viewpoints emerged between him and the central government, particularly concerning Kashmir's status. In 1953, he was removed from his position and subjected to detention for an extended period. Subsequent leadership lacked comparable public backing and struggled to govern the state, largely owing to backing from the central authority. Furthermore, various elections were tainted by grave accusations of misconduct and manipulation.
