Mahatma Gandhi in the context of "Self-government"

A princely state (also called native state) was a nominally sovereign entity of the British Raj that was not directly governed by the British, but rather by an indigenous ruler under a form of indirect rule, subject to a subsidiary alliance and the suzerainty or paramountcy of the British Crown.

In 1920, the Indian National Congress party under the leadership of Mahatma Gandhi declared swaraj (self-rule) for Indians as its goal and asked the princes of India to establish responsible government. Jawaharlal Nehru played a major role in pushing Congress to confront the princely states and declared in 1929 that "only people who have the right to determine the future of the Princely States must be the people of these States". In 1937, the Congress won in most parts of India (excluding the princely states) in the 1937 state elections, and started to intervene in the affairs of the states. In the same year, Gandhi played a major role in proposing a federation involving a union between British India and the princely states, with an Indian central government. In 1946, Nehru observed that no princely state could prevail militarily against the army of independent India.

Hindustani is an Indo-Aryan language spoken in North India and Pakistan as the lingua franca of the region. It is also spoken by the Deccani-speaking community in the Deccan Plateau. Hindustani is a pluricentric language with two standard registers, known as Hindi (Prakritised and Sanskritised register written in the Brahmic script) and Urdu (Persianised and Arabised register written in the Perso-Arabic script) which serve as official languages of India and Pakistan, respectively. Thus, it is also called Hindi–Urdu. Colloquial registers of the language fall on a spectrum between these standards.

The concept of a Hindustani language as a "unifying language" or "fusion language" that could transcend communal and religious divisions across the subcontinent was endorsed by Mahatma Gandhi, as it was not seen to be associated with either the Hindu or Muslim communities as was the case with Hindi and Urdu respectively, and it was also considered a simpler language for people to learn. The conversion from Hindi to Urdu (or vice versa) is generally achieved by merely transliterating between the two scripts. Translation, on the other hand, is generally only required for religious and literary texts.

Nonviolence is the practice of working for social change without causing harm to others, under any condition. It may come from the belief that hurting people, animals and/or the environment is unnecessary to achieve an outcome, and it may refer to a general philosophy of abstention from violence. It may be based on moral, religious or spiritual principles. The reasons for it may be strategic or pragmatic; failure to distinguish between the two can lead to distortion in the concept's meaning and effectiveness, which can subsequently result in confusion. Although both principled and pragmatic nonviolent approaches preach for nonviolence, they may have distinct motives, goals, philosophies, and techniques. However, rather than debating the best practice between the two approaches, both can indicate alternative paths for those who do not want to use violence.

Nonviolence has "active" or "activist" elements, in that believers generally accept the need for nonviolence as a means to achieve political and social change. Thus, for example, Tolstoyan and Gandhian philosophies on nonviolence seek social change while rejecting the use of violence, seeing nonviolent action (also called civil resistance) as an alternative to either passive acceptance of oppression or armed struggle against it. In general, advocates of an activist philosophy of nonviolence use diverse methods in their campaigns for social change, including critical forms of education and persuasion, mass noncooperation, civil disobedience, nonviolent direct action, constructive program, and social, political, cultural and economic forms of intervention.

Peace is a state of harmony in the absence of hostility and violence. In a societal sense, peace is commonly used to mean a lack of conflict (such as war) and freedom from fear of violence between individuals or groups.

Promotion of peace is a core tenet of many philosophies, religions, and ideologies, many of which consider it a core tenet of their philosophy. Some examples are: religions such as Buddhism and Christianity, important figures like Gandhi, and throughout literature like "Perpetual Peace: A Philosophical Sketch" by Immanuel Kant, "The Art of Peace" by Morihei Ueshiba, or ideologies that strictly adhere to it such as Pacifism within a sociopolitical scope. It is a frequent subject of symbolism and features prominently in art and other cultural traditions.

Civil resistance is a form of political action that relies on the use of nonviolent resistance by ordinary people to challenge a particular power, force, policy or regime. Civil resistance operates through appeals to the adversary, pressure and coercion: it can involve systematic attempts to undermine or expose the adversary's sources of power (or pillars of support, such as police, military, clergy, business elite, etc.). Forms of action have included demonstrations, vigils and petitions; strikes, go-slows, boycotts and emigration movements; and sit-ins, occupations, constructive program, and the creation of parallel institutions of government.

Some civil resistance movements' motivations for avoiding violence are generally related to context, including a society's values and its experience of war and violence, rather than to any absolute ethical principle. Civil resistance cases can be found throughout history and in many modern struggles, against both tyrannical rulers and democratically elected governments. Mahatma Gandhi led the first documented civil resistance campaign (using three primary tactics: civil disobedience, marches, and creation of parallel institutions) to free India from British imperialism. The phenomenon of civil resistance is often associated with the advancement of human rights and democracy.

The 1930s (pronounced "nineteen-thirties" and commonly abbreviated as "the '30s" or "the Thirties") was a decade that began on January 1, 1930, and ended on December 31, 1939. In the United States, the Dust Bowl led to the nickname the "Dirty Thirties".

The decade was defined by a global economic and political crisis that culminated in the Second World War. It saw the collapse of the international financial system, beginning with the Wall Street crash of 1929, the largest stock market crash in American history. The subsequent economic downfall, called the Great Depression, had traumatic social effects worldwide, leading to widespread poverty and unemployment, especially in the economic superpower of the United States and in Germany, which was already struggling with the payment of reparations for the First World War. The Dust Bowl in the United States (which led to the nickname the "Dirty Thirties") exacerbated the scarcity of wealth. U.S. President Franklin D. Roosevelt, who took office in 1933, introduced a program of broad-scale social reforms and stimulus plans called the New Deal in response to the crisis. The Soviet Union's second five-year plan gave heavy industry top priority, putting the Soviet Union not far behind Germany as one of the major steel-producing countries of the world, while also improving communications. First-wave feminism made advances, with women gaining the right to vote in South Africa (1930, whites only), Brazil (1933), and Cuba (1933). Following the rise of Adolf Hitler and the emergence of the NSDAP as the country's sole legal party in 1933, Germany imposed a series of laws which discriminated against Jews and other ethnic minorities.
