The Partition of Bengal made by Lord Curzon in 1905 lasted until

States that the partition was annulled in 1911 and gives the official reason (to curb revolutionary terrorism).

A student can combine this date (1911 annulment) with the basic external fact that World War I began in 1914 to judge whether the annulment occurred during the War.

Explains that Britain recruited a vast contingent of Indians to serve in Europe, Africa and West Asia during the First World War.

A student can use this to connect British wartime manpower needs (1914–18) to possible policy changes and then compare timing with the 1911 annulment noted elsewhere.

Gives the exact announcement date of the 1905 partition and frames it as a key trigger for intensified nationalist politics.

Use this to establish the start date of the partition (1905) and then compare the duration until annulment (1911) versus the WWI period (basic external knowledge).

Describes the Swadeshi and Boycott movement beginning with the 1905 partition and the political consequences that followed.

A student can infer that strong nationalist agitation followed partition and then consider whether the British response (annulment) was prompted by pre‑War political factors rather than wartime troop needs.

Presents administrative reasons given for partition (relief of Bengal, development of Assam) and shows partition was debated and planned well before 1905.

A student could contrast stated administrative motives and the chronology of planning (late 19th/early 20th century) with the timing of annulment and WWI to assess causal links.

Explicitly states that the Coronation Durbar of King George V was held in Delhi in 1911 (places the monarch in Delhi that year).

A student could check whether the annulment announcement coincided with that Durbar or was publicly declared there.

Says the partition of Bengal was decided to be annulled in 1911 (gives the date of annulment).

Combine this date with the Durbar date to suspect a temporal link and then verify whether the Durbar was the venue of the announcement.

Explains Curzon originated and promoted the partition of Bengal (links Curzon to the 1905 partition policy being later reversed).

Knowing Curzon enacted the partition, a student can focus on 1911 reversal sources to see who announced its abrogation and where.

Describes the original 1903–05 partition plan and administrative details (establishes the Act/policy that would later be annulled).

Use this background to search 1911 records of formal annulment documents or proclamations and whether they were promulgated at the Durbar.

Gives the formal date when Curzon issued the order dividing Bengal (20 July 1905) and describes the two new units; establishes the partition's origin and precise starting action.

A student can combine this start-date with outside timelines (e.g., dates of later administrative orders) to check whether the division persisted up to 1930.

States the date the partition 'took effect' (16 October 1905), confirming when the administrative change became operative.

Use this operative date together with external records of any subsequent reversals/annulments to test if it remained in force until 1930.

Gives the clear date when Gandhi formally launched the Civil Disobedience Movement (6 April 1930), providing the endpoint date against which to compare the partition's duration.

Compare the 1905 effective date (from snippets above) with this 1930 date and then consult historical sources for any administrative change(s) between them.

Reports specific Bengal organisational activity tied to Gandhi's civil disobedience campaign, indicating the movement reached Bengal in 1930 and showing Bengal remained a relevant administrative/political unit at that time.

A student could use this to infer Bengal's continued political identity in 1930 and then check if the 1905 administrative division still existed or had been reversed by then.

Gives the exact date the 1905 partition 'took effect' (16 October 1905), establishing a concrete starting point for any continuity question.

A student could compare this start date to 1947 maps/records to see if the same administrative unit persisted until partition of India.

Describes the 1903–1905 scheme creating two provinces: 'Bengal' (with Calcutta) and 'Eastern Bengal and Assam' (with Dacca as capital), specifying the territorial composition and capitals.

Using a historical map or list of provinces in 1947, a student can check whether 'Eastern Bengal and Assam' (or a successor) corresponds to the East Bengal that joined Pakistan.

States the partition was formally announced in July 1905 and came into force in October 1905, emphasising its formal administrative implementation.

A student could trace administrative orders/records from 1905 to 1947 to test whether those implemented boundaries remained or were altered before 1947.

Explains the 1947 outcome: legislative assemblies of Bengal decided in favour of partition and 'East Bengal' joined Pakistan — linking the 1947 provincial entity name ('East Bengal') to the partition outcome.

Compare the 1905 entity 'Eastern Bengal and Assam' (from 1905) with the 1947 entity 'East Bengal' to see if they are territorially the same or had been reorganised in the intervening period.

Notes the two parts created in 1905 were 'Eastern Bengal and Assam' (population details) and 'the rest of Bengal', highlighting that the 1905 partition separated Assam with eastern Bengal from western parts.

A student could use population/territorial descriptions plus external maps to judge whether the eastern partition in 1905 corresponds territorially to East Bengal of 1947.
