Paper II applies Paper I’s theoretical tools to actual historical periods, organizations, major powers, South Asia, and current security issues. Build timelines where chronology genuinely matters, but never stop at chronology alone — explain why actors made particular choices, what constraints they faced, and how those choices changed regional or international outcomes. Use chronology throughout to identify a change in power distribution, alliances, ideology, or institutions, then explain why that change actually altered state behaviour — a historical answer becomes genuinely analytical only when it shows the transition from one international order to another, rather than simply listing events in sequence.
A. Interwar Crisis and the Second World War
The 1917 Russian Revolutions removed the imperial order in Russia and eventually created the Soviet state, introducing a revolutionary socialist power into international politics for the first time; the Bolshevik victory affected wartime diplomacy, ideology, international communist movements, and later great-power relations, and fear of revolution spreading influenced politics across Europe well beyond Russia’s own borders. Fascist regimes then challenged liberal democracy and the post-WWI settlement through authoritarian nationalism, militarism, and territorial expansion; Italian Fascism and German Nazism differed in important ways, especially in Nazi racial ideology specifically, but both contributed to destabilizing interwar Europe. The League of Nations was created after WWI to promote collective security and peaceful dispute settlement; it introduced genuine institutional innovations but lacked reliable enforcement mechanisms and full great-power commitment — the United States never joined, and major aggressor states either withdrew from or openly defied it, lessons that directly shaped later UN institutional design.
WWII arose from interacting causes: unresolved post-WWI grievances, aggressive territorial expansion, ideological conflict, economic crisis, the failure of appeasement, and the broader breakdown of collective security together. Its consequences transformed the entire international system: massive destruction, the creation of the UN, the rise of the US and Soviet Union as genuine superpowers, accelerated decolonization, nuclear weapons, and an entirely new international economic order — WWII is the clearest example in this whole subject of a single event fundamentally restructuring the international system rather than merely adding one more historical episode to it.
B. Decolonization and the Cold War
Decolonization dismantled European empires and created a large number of new sovereign states after WWII, driven by nationalist movements within colonies, weakened colonial powers exhausted by the war, changing international norms, superpower rivalry (both superpowers had reasons to court newly independent states), and the UN’s own founding principles; these new states then faced immediate challenges around development, borders, institution-building, and whether to align with a Cold War bloc — the Bandung Conference and the resulting Non-Aligned Movement offered many of them a genuine third path. After WWII, Europe’s relative power declined sharply while the United States and Soviet Union emerged as military, ideological, and economic superpowers; their rivalry, once their wartime alliance broke down over genuinely incompatible post-war visions, produced competing alliance systems, proxy conflicts, an arms race, and rival economic and political models offered to the rest of the world.
Early Cold War “tight bipolarity” organized much of world politics around two clearly opposing blocs: NATO and the Warsaw Pact institutionalized this military rivalry formally, while crises in Berlin, Korea, and Cuba demonstrated the genuine risk of escalation between two nuclear-armed sides — though some states still resisted full bloc alignment, prefiguring the Non-Aligned Movement. Détente, especially from the late 1960s and through the 1970s, was a period of reduced US-Soviet tension and greater negotiation: arms-control talks, West Germany’s Ostpolitik, the Sino-American opening, and more independent behaviour among allies all made the bipolar system considerably less rigid, though underlying rivalry clearly continued beneath this surface calm. Tensions revived in the late 1970s and 1980s around Afghanistan, renewed arms competition, and various regional conflicts, before Gorbachev’s reforms, mounting Soviet economic strain, and rapid political change across Eastern Europe together contributed to the Soviet Union’s collapse in 1991 — no single factor fully explains the Cold War’s end, and any strong answer should draw on several of these causes together rather than picking just one.
C. The Post-Cold-War Order
Fukuyama’s “end of history” thesis argued that liberal democracy had won the central ideological contest of modernity after communism’s collapse — the thesis concerns ideological evolution specifically, not the literal end of wars or events, and later authoritarian resilience, resurgent nationalism, ongoing conflict, and democratic backsliding in various countries have all generated substantial criticism of the thesis’s optimism. Samuel Huntington’s “clash of civilizations” thesis proposed that major post-Cold-War conflicts would increasingly follow cultural and civilizational fault lines rather than ideological ones; the argument usefully drew attention to identity and culture as drivers of conflict, but it is widely criticized for treating entire civilizations as overly coherent, internally undifferentiated blocs, for underplaying real internal diversity within each “civilization,” and for downplaying material and political causes of conflict that have nothing to do with cultural identity at all.
Transnational terrorism became a major security focus in the post-Cold-War order, especially after September 11, 2001, reshaping approaches to war, surveillance, alliance behaviour, and military intervention; terrorism is properly understood as a tactic used by varied actors pursuing varied goals, and it should never be equated with any single religion or population as a whole — counter-terrorism policy involves genuine trade-offs among intelligence gathering, use of force, legal process, individual rights, and efforts to prevent radicalization in the first place. After the Soviet collapse, the United States held an unusually dominant global position, often called the “unipolar moment”; over time, China’s economic and military rise, Russia’s regional reassertion, the growing weight of other regional powers, and the wider diffusion of economic and technological capability have made the global distribution of power considerably more genuinely contested. Whether to call today’s system “multipolar” is itself debated among scholars, precisely because military, financial, technological, and institutional power are distributed quite differently across these different domains — a state can be a leading power in one domain while remaining comparatively weak in another.
The International System from 1917 to the Present key takeaways: WWI and WWII both fundamentally restructured the international system, not merely added to its history — each created new institutions and shifted the underlying distribution of power. The Cold War moved through genuinely distinct phases (tight bipolarity, détente, renewed tension, collapse), and no single explanation accounts for its ending on its own. The end-of-history and clash-of-civilizations theses are both frequently oversimplified in popular discussion and deserve careful, precise statement along with their major criticisms. Today’s polarity debate is genuinely unresolved because power is distributed unevenly across military, economic, technological, and institutional domains simultaneously, rather than concentrating uniformly in one or a few states.
