In the history of organised peasant movements in India, in which year was the All India Kisan Sabha (All India Farmers’ Union) founded at the national level?

Introduction / Context:
This question relates to the organised peasant movement in modern India. As the freedom struggle grew, peasants and rural tenants began forming their own organisations to fight against high rents, unfair taxes and feudal oppression. The All India Kisan Sabha became a major platform for articulating peasant demands at the national level. Knowing the year of its foundation helps place peasant mobilisation in the larger timeline of the national movement.

Given Data / Assumptions:
- The organisation mentioned is the All India Kisan Sabha, also called the All India Farmers Union.
- The question asks in which year it was founded at the national level.
- The options list various decades: 1936, 1946, 1956, 1966 and 1920.
- We assume awareness that the main phase of organised peasant movements gained strength in the 1930s.

Concept / Approach:
The All India Kisan Sabha was formally established in 1936 at Lucknow. It emerged at a time when economic depression, rising peasant distress and the nationalist struggle all converged. Leaders like Swami Sahajanand Saraswati, N.G. Ranga and others played important roles in its formation. The organisation sought to represent peasants interests, campaign for reduction of rent and land revenue, and link agrarian issues with the broader freedom movement. Therefore, among the given years, 1936 is the correct one.

Step-by-Step Solution:
Step 1: Recall that the 1930s saw growing peasant unrest and the rise of agrarian organisations in India. Step 2: Remember that the All India Kisan Sabha was founded in 1936 at Lucknow to coordinate peasant struggles nationwide. Step 3: Note that 1946, 1956 and 1966 represent later phases, including the immediate post war and post independence periods. Step 4: Recognise that 1920 is too early for this united organisation, although local peasant movements existed. Step 5: Based on this timeline, choose 1936 as the year of foundation.

Verification / Alternative check:
To verify, think of the broader chronology: Non Cooperation Movement in the early 1920s, Civil Disobedience and the Great Depression in the early 1930s, and then a surge of peasant organisations in the mid 1930s. History texts on agrarian movements commonly state that the All India Kisan Sabha was formed in 1936 at Lucknow, with Swami Sahajanand Saraswati as its first president. This clear and frequently repeated fact confirms the correct year.

Why Other Options Are Wrong:
1946: By this time, the All India Kisan Sabha already existed; 1946 is closer to the period of provincial elections, naval mutiny and post war ferment.
1956: This is well into the post independence period and relates more to reorganisation of states and other issues, not to the founding of the Kisan Sabha.
1966: By this time, the Green Revolution was just beginning, long after the All India Kisan Sabha had been formed.
1920: Although peasant struggles existed, the unified All India Kisan Sabha was not yet established at this time.

Common Pitfalls:
Students sometimes guess dates based on round numbers or general knowledge of the freedom struggle, picking years like 1946 or 1956 simply because they seem important. Another pitfall is to confuse the founding of individual peasant unions with the formation of a national level organisation. Keeping the key association Kisan Sabha 1936 in mind helps fix this fact more firmly and avoids misplacing it in the timeline.

Final Answer:
The All India Kisan Sabha was founded in 1936.
