Dyarchy

History glossary

Also called: Diarchy · Topic: Framing the Indian Constitution · NCERT: Class 12, Ch 4 "Framing the Constitution"

Meaning

Dyarchy (also spelt diarchy, meaning "rule by two") was the system of "double government" that the Government of India Act, 1919 set up in the provinces of British India. The subjects of provincial government were split into two lists. Transferred subjects were run by Indian ministers who answered to the elected legislature. Reserved subjects stayed with the Governor and his executive council, who did not answer to the legislature. The 1935 Act ended dyarchy in the provinces, but it planned a new dyarchy at the Centre.

It matters because it was the first time Indian ministers became even partly responsible to an elected legislature. It also shows what NCERT calls participation without power: Indians got a share in government, but the British kept real control.

Explanation

Background: why dyarchy came

The 1909 Act came first. It let more Indians into the councils, but it gave them no control over the executive (the people who actually run the government).
Demand for self-government grew during the First World War. In 1917 the Secretary of State, Edwin Montagu, announced that Britain's aim was the "gradual development of self-governing institutions" and "responsible government" in India.
The result was the Montagu–Chelmsford Reforms. These were turned into the Government of India Act, 1919, and the new system began working in 1921.
The idea behind it: hand over only "safe" subjects to Indians first, as a kind of training, and keep the important ones in British hands.

Main features: the two lists

Transferred subjects (handed to Indians):
examples: education, public health, local self-government, agriculture
run by ministers chosen from the elected members of the provincial legislature
the ministers were answerable to the legislature, so the legislature could remove them by a vote
Reserved subjects (kept by the British):
examples: law and order (police), justice, finance, land revenue
run by the Governor and his Executive Council
not answerable to the legislature; they answered to the Governor-General and London
The Governor kept the final word. He could overrule ministers, and he could also certify laws or spending that the legislature had rejected.
At the Centre there was no dyarchy under the 1919 Act. The central executive stayed fully under the Governor-General. A Central Legislative Assembly was created, which sat from 1921 [2].

How it worked in practice

The ministers had responsibility but very little power:
Finance was a reserved subject, so ministers had to ask the reserved side for money for schools or hospitals.
The police and the civil services stayed outside their control.
The Governor could override them, so the legislature often blamed them for things they could not control.
The Congress at first boycotted the new councils during the Non-Cooperation Movement. Later the Swarajists entered the councils to block them from inside.
The Simon Commission (appointed in 1927) reviewed how the 1919 Act was working. Its report and the debates that followed led to the 1935 Act.

Results: abolition and what came after

The Government of India Act, 1935 abolished dyarchy in the provinces. It brought in provincial autonomy: all provincial subjects went to ministers answerable to the legislature. In the study note's words, the executive became "almost entirely" responsible to the legislature, compared with "partly" under 1919.
The same Act planned a dyarchy at the Centre. Defence, external affairs, ecclesiastical affairs and tribal areas were to stay reserved under the Governor-General. This part depended on the proposed All-India Federation, which never came into force, because not enough princely states agreed to join.
Provincial autonomy was tested in 1937, when Congress ministries were formed in 8 of the 11 provinces.
Even so, NCERT stresses the limits:
These Acts were passed by the colonial government, not by Indians.
Even under the 1935 Act only 10–15 per cent of adults could vote.
Legislatures stayed under British-appointed Governors.

Time, place and evidence

Period: British rule. Dyarchy was introduced by the 1919 Act, worked in the provinces from 1921, and ended there when provincial autonomy began under the 1935 Act (ministries formed in 1937).
Place: the major provinces of British India, governed by Governors. It did not apply to the princely states.
Key people:
Edwin Montagu (Secretary of State) and Lord Chelmsford (Viceroy), whose report shaped the 1919 Act
Dr Sachchidananda Sinha, who sat in the Imperial Legislative Council from 1910 and in the Central Legislative Assembly from 1921, the Assembly created by the same reforms [2]. He later chaired the first sitting of the Constituent Assembly as its oldest member [2].
How we know: the text of the Government of India Act, 1919, the Montagu–Chelmsford Report, the Simon Commission Report, and NCERT Class 12, Ch 4 "Framing the Constitution". The chapter places 1919 in the chain of colonial Acts (1909, 1919, 1935) that it contrasts with the Constituent Assembly.

Don't confuse with

Provincial autonomy (1935 Act): this ended dyarchy in the provinces. All provincial subjects went to responsible ministers. Under dyarchy, only the transferred subjects did.
Dyarchy at the Centre (1935 Act): this was planned in 1935, but it never actually came into force. The provincial dyarchy of 1919 did work, from 1921 to 1937.
Morley–Minto Reforms (1909 Act): these enlarged the councils and brought in separate electorates for Muslims. They gave ministers no responsibility to the legislature, which is why there was no dyarchy in 1909.
Bicameral central legislature (1919 Act): the same Act created two houses at the Centre. That is a separate feature. The 1919 Act's dyarchy applied only to the provinces, not to the Centre.

Prelims Hooks

Dyarchy was introduced in the provinces by the Government of India Act, 1919 (Montagu–Chelmsford Reforms) and came into effect in 1921.
Transferred subjects (education, health, local self-government, agriculture) went to ministers answerable to the legislature. Reserved subjects (police, justice, finance, land revenue) stayed with the Governor and Executive Council.
Trap: the 1935 Act abolished dyarchy in the provinces but provided for it at the Centre. The central dyarchy never came into operation.
Order to remember: 1909 (no responsibility) → 1919 (executive partly responsible to provincial legislatures) → 1935 (executive almost entirely responsible) → 1937 (Congress ministries in 8 of 11 provinces).
Under the 1935 Act, which followed dyarchy, only 10–15 per cent of adults had the vote.
Dr Sachchidananda Sinha sat in the Central Legislative Assembly from 1921 (created by the 1919 reforms) and later presided over the Constituent Assembly's first sitting as its oldest member [2].

Mains Points

Continuity or rupture?
One view: dyarchy was the first school of responsible government. Indian ministers learnt to run departments, face a legislature and pass budgets, and the later Constitution used this experience.
NCERT's view: Acts like 1919 gave participation without power. They were granted from above, the Governor could overrule ministers, and the electorate was tiny. So 1946 was a rupture, a clean break when Indians wrote their own rules with the goal of universal adult franchise.
Why dyarchy failed:
It split power in an unworkable way. Ministers had duties without money (finance was reserved) and without control of the police or the services.
The Governor's override powers made responsibility to the legislature mostly a formality.
This failure pushed the British towards provincial autonomy in 1935, and pushed Indians towards demanding a Constituent Assembly of their own.
The legacy is useful in answers on federalism and responsible government:
The split into "lists" of subjects foreshadows the later division of powers between Centre and states.
The principle that ministers must answer to an elected house became the core of India's parliamentary system. The difference is that this time it was chosen by Indians, not handed down by the colonial power.
