Who among the following were the founders of the "Hind Mazdoor Sabha" established in 1948 ?

Identifies P. Krishna Pillai as a founder of the Kerala Communist movement — shows Kerala communist leaders in that era did found major political organizations.

A student could check whether leaders active in Kerala communist politics around 1948 also participated in creating national labour bodies like Hind Mazdoor Sabha.

Also records P. Krishna Pillai's prominent activist role in the 1930s and later as founder of the Kerala Communist movement — indicates continuity from regional political activism to institutional founding roles.

Use this pattern (regional activist → founder of organizations) and look up records of labour union foundations in 1948 for involvement of such activists.

Lists E.M.S. Namboodiripad among notable CPI leaders — confirms he was a prominent communist figure who might plausibly be involved in labour movement initiatives.

Cross-reference prominent CPI leaders' activities in 1947–49 (using external timelines) to see if they helped establish national trade unions such as Hind Mazdoor Sabha.

Gives examples of political leaders founding formal organizations (e.g., G. Durgabai Deshmukh founding Andhra Mahila Sabha), establishing a general pattern that political activists often become organizational founders.

Apply this general rule to the named individuals: investigate whether these specific activists transitioned into founding or leading labour organisations in 1948.

Shows the text contains many regional leaders who led mass/political movements and founded organizations, implying the source treats leadership-to-foundership as common.

Use the source's pattern of documenting founders to search within similar sources or appendices for a listing of founders of Hind Mazdoor Sabha in 1948.

Identifies Jayaprakash Narayan as a lifelong socialist leader, founder–general secretary of the Congress Socialist Party and the Socialist Party — linking him to labour and socialist organising traditions.

A student could use this pattern (socialist leaders often helping form labour federations) to suspect JP's involvement in founding a major trade-union body in 1948 and then check labour-history sources for HMS founders.

Notes Jayaprakash Narayan's move away from party politics into constructive/community work and 'partyless democracy' — suggesting continuity with mass/social movements rather than party-based roles.

This supports seeking JP's role in non-party organisations (like labour federations) around the late 1940s; a student could check 1948 labour records or HMS founding lists.

Describes Deen Dayal Upadhyaya as a full‑time RSS worker and founder member/leader of the Bharatiya Jana Sangh, indicating a right‑of‑centre ideological and organisational trajectory.

Given his RSS/BJS alignment, a student might judge it less likely (but not impossible) he co‑founded a broadly socialist/worker federation in 1948 and therefore look for primary lists of HMS founders to confirm or refute his name.

Shows M.N. Roy was charged in the Kanpur Conspiracy case and that other contemporaries organised trade unions and May Day activities — linking Roy to radical/organising traditions.

A student could extend this by checking Roy's recorded post‑war activities (given his earlier trade‑union/communist involvement) to see if he participated in founding a national labour body in 1948.

Describes the formation of multiple political groupings (Socialist Party led by JP and others) active in the immediate post‑independence period, showing that prominent political actors were founding new organisations in this era.

A student could use this pattern — that 1940s leaders formed new parties and mass organisations — to plausibly investigate whether those same leaders were involved in founding labour federations like Hind Mazdoor Sabha in 1948.

Describes the immediate post‑Independence period (late 1940s) when many prominent leaders formed new parties/organisations (e.g., Kisan Mazdoor Praja Party, Socialist Party).

A student could use this pattern to infer that formation of a national trade‑union federation in 1948 fits the era when leaders often founded new organisations, so one should check if the named individuals were active in forming labour bodies then.

Gives K. Kamaraj's profile as a high‑profile Congress leader active in Madras politics across the 1940s–60s.

A student could extend this by checking whether Kamaraj’s known activities included labour/trade‑union initiatives or founding roles in national federations around 1948.

Mentions C.P. Ramaswami Iyer as a prominent political figure engaged in national conferences pre‑Independence, indicating his prominence and possible involvement in organisational initiatives.

A student could use this to justify looking for C.P. Ramaswami Iyer’s post‑1947 organisational roles (including labour or industrial relations) to test whether he helped found a 1948 trade union federation.

Lists national leaders (e.g., G.B. Pant) involved in founding/leading major post‑Independence institutions, showing that nationally prominent figures often appear as founders of major bodies.

By analogy, a researcher could check whether Veeresalingam Pantulu or the other named figures had comparable national‑level roles that would make them likely founders of a 1948 national trade union body.

Shows variety of regional and social movements and leaders (Justice Party, Self‑Respect movement, Ambedkarites, socialists) active in the era, indicating multiple organisational streams feeding national institutions.

A student could use this to reason that founders of a pan‑Indian trade union federation might come from diverse regional/social movements and thus check whether the three named individuals represented such streams.
