What is Federalism?

India is a country of enormous scale and diversity -- home to more than twenty major languages and several hundred smaller ones, multiple major religions, and millions of people belonging to indigenous communities spread across very different regions. Despite all this, the country has always shared one landmass and one common history, most visibly the shared experience of the freedom struggle -- which is exactly why India's leaders came to describe the country as one of "unity in diversity."

Federalism is a way of organising government in which power is shared between two (or more) levels of government -- a national or central government, and one or more regional or State governments -- with the division of powers laid down by the Constitution itself. Each level of government is autonomous within its own assigned area, and neither level can simply override or abolish the other on its own; the arrangement is protected by the Constitution rather than left to the goodwill of either government. Federalism is not one fixed formula applied identically everywhere -- it is a governing principle that has developed differently depending on each country's own history, so American federalism, one of the earliest large-scale attempts at building a federal polity, looks quite different from German or Indian federalism.

Even so, a few core ideas recur across federal systems. Federalism is essentially a mechanism to accommodate two sets of politics at once -- one operating at the regional/State level and one at the national level -- with each government sovereign in its own sphere; some federations even allow dual citizenship, though India has only a single, common citizenship. People in a federation typically carry two overlapping identities and loyalties, seeing themselves as belonging both to their region and to the nation as a whole (a person may identify as a Gujarati or a Jharkhandi as well as an Indian), with each level of government holding its own distinct powers. This dual arrangement is normally spelt out in a written constitution treated as supreme and as the actual source of power for both levels -- matters concerning the whole country, like defence or currency, belong to the centre, while matters of local or regional concern are left to the States. And because disputes over exactly which government holds power over what are bound to arise, federations rely on an independent judiciary to settle such disputes on constitutional grounds.

But a federal constitution on paper does not by itself guarantee that a country stays united -- how federalism actually works out depends heavily on real politics, culture, ideology and history. A shared culture of trust, cooperation, mutual respect and restraint is what lets a federation function smoothly, and political parties play a large role in shaping how the constitutional design plays out on the ground. If one State, one linguistic community, or one ideology comes to dominate the whole federation, it can breed deep resentment among those left unheard -- in extreme cases fuelling demands for secession or even civil war. The USSR broke apart in 1989 largely from excessive centralisation and Russia's domination over regions with their own distinct languages and cultures, such as Uzbekistan; Czechoslovakia, Yugoslavia and Pakistan went through similar divisions; and Canada came close to splitting between its English- and French-speaking regions. All of these were federations, yet a federal constitution alone did not keep them together -- which is exactly why India remaining united since 1947, after a painful partition, counts as a real achievement, and why the actual practice of federalism matters as much as its constitutional design.

The Federation of the West Indies illustrates just how fragile such arrangements can be. Formed in 1958 by former British colonies in the Caribbean, it had a deliberately weak central government and let each unit run its own economy independently; that, combined with political rivalry among the units, led to its formal break-up by 1962. In 1973 the same islands signed the Treaty of Chaguaramas, setting up shared institutions instead -- a common legislature, a shared supreme court, a common currency, and to some extent a common market, known as the Caribbean Community, with a shared executive made up of the heads of government of the member states. The islands, in other words, could neither function as one single country nor stay entirely apart from each other. …
