Explanation:
India has a long history of land systems that have evolved over time. The traditional land system in the country was based on the zamindari system which was prevalent during the Mughal period. However, during the British rule, the land system underwent significant changes. The British introduced various land settlement systems such as the Permanent Settlement, Ryotwari Settlement, and Mahalwari Settlement.

Permanent Settlement:
The Permanent Settlement was introduced in Bengal, Bihar, and Orissa in 1793. This system was also known as the Zamindari System. Under this system, the British recognized the zamindars as the owners of the land. The zamindars were responsible for collecting revenue from the peasants and paying a fixed amount to the British government. This system was a departure from the traditional land system in the country as it introduced the concept of private property rights in land.

Ryotwari Settlement:
The Ryotwari Settlement was introduced in Madras, Bombay, and Assam in the early 19th century. This system was based on the principle of direct assessment of land revenue on individual cultivators. Under this system, the cultivators were recognized as the owners of the land. The cultivators had to pay the land revenue directly to the government. This system was a departure from the traditional land system in the country as it introduced the concept of individual land ownership.

Mahalwari Settlement:
The Mahalwari Settlement was introduced in the North-Western Provinces and Punjab in the mid-19th century. Under this system, the land revenue was assessed on the basis of the village or mahal. The revenue was collected from the entire village or mahal and not from individual cultivators. The village or mahal was recognized as the unit of assessment and ownership. This system was a departure from the traditional land system in the country as it introduced the concept of collective land ownership.

Conclusion:
Thus, it can be concluded that all three land settlement systems, i.e., Permanent Settlement, Ryotwari Settlement, and Mahalwari Settlement, departed fundamentally from the traditional land system in the country. These systems introduced new concepts of private property rights, individual land ownership, and collective land ownership.
