Medicine and health through time

This topic tracks how ideas about the cause, prevention and cure of disease changed from c1250 to the present day. OCR expects you to spot continuity AND change, and to explain WHY things changed using the key factors: religion, government, science and technology, war, communication, and the role of individuals.

Medieval medicine (c1250-c1500)

• Dominant theory was the Four Humours (Hippocrates/Galen): blood, phlegm, black bile, yellow bile - illness meant humours were out of balance.
• Treatments included bloodletting, purging and bathing to rebalance humours.
• The Church controlled learning; Galen's ideas were rarely challenged because they fitted Christian belief.
• The Black Death (1348-49) killed roughly a third of England's population; people blamed miasma (bad air), God's punishment and the position of the planets.
• Common mistake: don't say medieval people knew nothing - they had hospitals, herbal remedies and some surgery, they just lacked germ theory.

Renaissance medicine (c1500-1700)

• Vesalius corrected Galen's anatomy errors using human dissection (published 1543).
• William Harvey discovered the circulation of blood (1628), disproving Galen's idea that blood was made in the liver.
• Printing press (Gutenberg, c1440) spread new ideas faster across Europe.
• The Great Plague of London (1665) still showed old ideas persisting: flagellants, herbal charms and quarantine were used alongside newer thinking.

Medicine c1700-c1900

• Edward Jenner developed the smallpox vaccination in 1796, using cowpox matter.
• Louis Pasteur published Germ Theory in 1861, proving microbes cause disease.
• Robert Koch identified specific bacteria (anthrax, TB, cholera) in the 1870s-80s using new staining and photography techniques.
• Joseph Lister introduced antiseptic surgery using carbolic acid spray from 1865, cutting post-operative infection deaths.
• Public Health Act 1875 made local councils responsible for clean water, sewers and food safety - a big shift to government-led prevention.
• Common mistake: Pasteur explained WHY germs cause disease; Koch showed WHICH germ causes WHICH disease - don't mix them up.

Modern medicine (c1900-present)

• Alexander Fleming discovered penicillin in 1928; Florey and Chain mass-produced it for use by 1941, crucial in WWII.
• The NHS was founded on 5 July 1948, offering free healthcare at the point of use, funded by general taxation.
• DNA structure discovered by Watson and Crick in 1953, opening the door to genetic medicine.
• Magic bullets (targeted drugs), CT/MRI scanning and keyhole surgery all rely on 20th/21st-century technology.
• War acted as a major accelerator: WWI improved blood transfusion and plastic surgery; WWII sped up penicillin production.

Exam tip

Always link the example back to a factor (why did this happen when it did?) rather than just describing the event - OCR rewards explanation over narrative.

Warfare and conflict: the big picture

OCR GCSE History often assesses conflict through a British thematic study (e.g. Warfare and British Society, c1250-present) alongside period depth studies. The key skill is tracking CHANGE and CONTINUITY across centuries, and explaining WHY change happened using recurring factors: government, technology, communication, and the role of individuals.

The five recurring factors

• Government: control over recruitment, supply and finance (e.g. medieval feudal levy versus later centralised state armies).
• Technology: weapons and transport changes (longbow, gunpowder, rifling, tanks, aircraft).
• Communication: how fast orders and news travelled (messenger to telegraph to radio).
• Individuals: commanders and monarchs who drove reform.
• Ideas and beliefs: chivalry, nationalism, total war ideology.

Medieval warfare (c1250-1500)

• Armies were raised via feudal obligation, then increasingly through paid contracts (indentures) by the 1300s.
• The longbow was decisive at Crecy (1346) and Agincourt (1415), giving English archers a range and rate-of-fire advantage.
• Castles shifted from motte-and-bailey to concentric stone designs for better defence against siege engines.

Early modern warfare (c1500-1750)

• Gunpowder weapons (muskets, cannon) gradually replaced bows and armour became less useful against shot.
• The New Model Army (1645) under Parliament introduced professional, paid, disciplined soldiers rather than local levies.
• Siege warfare and star-shaped fortifications (trace italienne) responded to cannon fire.

Modern warfare (c1750-present)

• The Napoleonic Wars saw mass conscription and larger, faster-moving armies.
• The First World War (1914-18) introduced trench warfare, machine guns, poison gas and tanks (first used at the Somme, 1916).
• The Second World War (1939-45) was total war: whole civilian populations, economies and cities became targets (e.g. the Blitz).
• Since 1945, warfare has included nuclear deterrence, guerrilla and asymmetric conflict, and high-tech precision weapons.

Common mistakes

• Do not just describe battles narratively; the exam rewards explaining causes and consequences using the recurring factors.
• Do not treat change as always steady or continuous; some periods show rapid change (WW1) and others show long continuity (siege methods for centuries).
• Always link source or interpretation questions back to the specific historical context, not general assumptions.
• Remember OCR depth studies vary by exam board specification code; check which specific period option your course covers.

Germany 1890-1945: the big picture

This period covers Kaiser Wilhelm II's Germany, defeat in WWI, the fragile Weimar Republic, Hitler's rise, and the Nazi dictatorship through to collapse in 1945. OCR wants you to explain WHY change happened, not just list dates.

Kaiser Germany and WWI (1890-1918)

• Wilhelm II sacked Bismarck in 1890 and pursued Weltpolitik (world policy) - building a navy to rival Britain, which fed Anglo-German tension.
• Germany fought WWI 1914-1918 on two fronts; by autumn 1918 the army was exhausted and the Kaiser abdicated on 9 November 1918.
• The armistice was signed 11 November 1918 - Germany did NOT surrender on the battlefield, which fed the 'stab in the back' myth (Dolchstosslegende) blaming politicians, not the army.

The Treaty of Versailles, 1919

• Key terms to know exactly: Article 231 (War Guilt Clause), reparations set at £6.6 billion (132 billion gold marks) in 1921, army capped at 100,000, no air force, navy limited to 6 battleships, Rhineland demilitarised, Alsace-Lorraine returned to France, all colonies lost.
• Germans called it a Diktat (dictated peace) since they were not allowed to negotiate - this bitterness fuelled later extremism.

The Weimar Republic (1919-1933): strengths and weaknesses

• New constitution gave all adults over 20 the vote and used proportional representation - fair, but caused weak coalition governments.
• Article 48 let the President rule by emergency decree, bypassing the Reichstag - a loophole Hitler later exploited.
• Crises: Spartacist Uprising (1919), Kapp Putsch (1920), French/Belgian occupation of the Ruhr (1923) after Germany missed reparations, hyperinflation in 1923 (a loaf of bread reportedly cost billions of marks).

Common mistake: don't muddle 1923 hyperinflation with the 1929 Wall Street Crash - they are separate crises a decade apart with different causes.

• The 'Golden Age' under Gustav Stresemann (1923-1929): new currency (Rentenmark), the Dawes Plan (1924) rescheduled reparations, the Locarno Pact (1925), and joining the League of Nations (1926).

The Nazi rise to power (1929-1933)

• The Wall Street Crash (October 1929) triggered US loans being recalled, collapsing the German economy - unemployment hit around 6 million by 1932.
• Nazi seats in the Reichstag rose from 12 (1928) to 230 (July 1932) as voters turned to extremes.
• Hitler became Chancellor on 30 January 1933 - he was appointed by President Hindenburg, NOT elected as leader; this is a classic exam trap.
• The Reichstag Fire (27 February 1933) let Hitler pass the Reichstag Fire Decree, suspending civil liberties, followed by the Enabling Act (23 March 1933) which let him make laws without the Reichstag.

Consolidating the dictatorship

• The Night of the Long Knives (30 June-2 July 1934) removed SA leader Ernst Rohm and rivals.
• Hindenburg died 2 August 1934; Hitler merged Chancellor and President into 'Fuhrer' and the army swore personal loyalty to him.

Nazi Germany 1933-1945

• Control used the Gestapo, SS, propaganda (Goebbels), and the Nuremberg Laws (1935) stripping Jews of citizenship, escalating to Kristallnacht (November 1938) and ultimately the Holocaust.
• Economic policy: work creation schemes, autobahns, and rearmament defying Versailles limits cut unemployment sharply by 1936-37.
• WWII began 1 September 1939 (invasion of Poland); Germany surrendered 8 May 1945 (VE Day) after Hitler's suicide on 30 April 1945.

What is the Cold War?

The Cold War (1945-1991) was a period of tension between the USA (capitalism, democracy) and the USSR (communism, one-party state). No direct fighting between the two superpowers happened - hence 'cold' - but they fought through spies, propaganda, an arms race and proxy wars.

Origins, 1945-1949

• At Yalta (Feb 1945) the Big Three (Roosevelt, Churchill, Stalin) agreed on free elections in Eastern Europe and dividing Germany into zones.
• At Potsdam (Jul-Aug 1945) trust broke down - new leaders Truman and Attlee clashed with Stalin over reparations and Poland.
• Stalin built an 'Iron Curtain' of satellite states across Eastern Europe by 1948, breaking the Yalta promise of free elections.
• The Truman Doctrine (1947) pledged US money and support to any country resisting communism (containment).
• The Marshall Plan (1947) gave $13 billion of US aid to rebuild Western Europe and stop communism spreading through poverty.
• Common mistake: don't say the Cold War 'started' at one single event - it built up gradually through broken promises and mistrust.

Berlin, 1948-1961

• Berlin Blockade (Jun 1948-May 1949): Stalin cut all road/rail links to West Berlin to force the Allies out; the Allies responded with the Berlin Airlift, flying in supplies for 11 months until Stalin backed down.
• This led directly to NATO (1949, Western military alliance) and the Warsaw Pact (1955, Soviet military alliance).
• The Berlin Wall went up in August 1961 to stop East Germans fleeing to the West - a key symbol of a divided Europe.

Key crises

• Cuban Missile Crisis (October 1962): USSR placed nuclear missiles in Cuba, 90 miles from the USA. 13 days of tension, resolved when Khrushchev removed the missiles in exchange for a secret US promise to remove missiles from Turkey.
• Prague Spring (1968): Czechoslovakia's reforms crushed by Warsaw Pact tanks, showing Soviet control over satellite states.
• Common mistake: students confuse the Berlin Blockade (1948-49) with the Berlin Wall (1961) - they are 22 years and two different crises apart.

Detente and the end of the Cold War

• Detente (early 1970s) was a period of improved relations, including SALT I (1972) limiting nuclear weapons.
• Relations worsened again after the USSR invaded Afghanistan in 1979.
• Gorbachev's reforms (glasnost = openness, perestroika = restructuring) from 1985 loosened Soviet control.
• The Berlin Wall fell in November 1989; the USSR officially collapsed in December 1991, ending the Cold War.

Exam tips

• Always use precise dates and names - examiners reward specific detail over vague description.
• Explain causation (why something happened) not just narration (what happened) for the higher-mark questions.

Elizabeth's Court and Parliament

Elizabeth I became queen in 1558, aged 25, after the death of her half-sister Mary I. She never married, earning the nickname 'the Virgin Queen', and ruled until her death in 1603. Her Privy Council advised her on policy - key figures included William Cecil (Lord Burghley), her chief minister for most of the reign, and Robert Dudley, Earl of Leicester, a favourite and possible suitor. Parliament could raise taxes and pass laws, but Elizabeth controlled when it met and could veto its bills. Patronage (granting land, titles, and monopolies) kept nobles loyal without paying them directly.

The Religious Settlement

In 1559 Elizabeth introduced the Religious Settlement to create a compromise Protestant Church that most moderate Catholics and Protestants could accept. The Act of Supremacy made her 'Supreme Governor' of the Church (not 'Supreme Head', to soften opposition). The Act of Uniformity set one Book of Common Prayer and made church attendance compulsory, with a 12 pence fine (recusancy fine) for those who missed the Sunday service. Common mistake: students confuse Supreme Governor with Supreme Head - Henry VIII was Head, Elizabeth was Governor.

Threats and Plots

Elizabeth faced three major Catholic plots: the Ridolfi Plot (1571), the Throckmorton Plot (1583), and the Babington Plot (1586), the last leading directly to the execution of Mary, Queen of Scots in February 1587. The Northern Rebellion (1569) was the biggest rebellion of the reign, led by the Earls of Northumberland and Westmorland. The Spanish Armada arrived in 1588, sent by Philip II of Spain, with around 130 ships - it was defeated by a combination of English naval tactics (fireships at Calais) and storms ('the Protestant Wind').

Society: Poverty and Exploration

Bad harvests, population growth, and the decline of the wool trade caused rising poverty. The 1601 Poor Law made parishes responsible for supporting the 'deserving poor' (elderly, sick) through a local poor rate tax, while the 'undeserving poor' (idle beggars) could be whipped or imprisoned. Common mistake: don't mix up 1597 and 1601 Poor Laws - 1601 is the one usually quoted as the settled system. Exploration expanded under Francis Drake, who circumnavigated the globe (1577-1580), and Walter Raleigh, who attempted to found the Roanoke colony in Virginia (1585) - it failed and is known as the 'Lost Colony'.

Why source questions matter

OCR GCSE History always tests two separate skills: working with SOURCES (contemporary evidence from the time) and working with INTERPRETATIONS (later historians' views written after the event, using hindsight). Mixing these up is the most common mistake candidates make.

Sources: the key questions to ask

• WHO produced it, and WHEN — a source written by a government official in wartime will differ from a private letter.
• WHY was it produced (its PURPOSE) — propaganda, private diary, official report, newspaper article all have different aims.
• What is its NOP: Nature, Origin, Purpose. Always cover all three in an answer.
• CONTENT — what does it actually say or show, and what can you infer beyond the literal words.
• PROVENANCE — the background info given about the source (who, when, where) is often the key to unlocking its value.

Utility and reliability

• Utility means how USEFUL a source is for a specific enquiry — a biased source can still be useful, e.g. for showing what propaganda looked like.
• Reliability is about accuracy and trustworthiness — never dismiss a source as 'unreliable' just because it is biased; explain HOW the bias affects its value.
• Never say a source is 'reliable' or 'unreliable' full stop — always link judgement to the specific question being asked.
• Cross-reference: compare two sources and identify points of agreement and disagreement, using specific details from each.

Interpretations

• An interpretation is a historian's INTERPRETATION of the past, produced with the benefit of hindsight and often using multiple sources.
• Interpretations can differ because historians use different evidence, have different perspectives, or write for different audiences/purposes.
• To explain WHY two interpretations differ, look at: different evidence used, different emphasis, when it was written, the historian's own viewpoint or agenda.
• Use the phrase 'this suggests' or 'this implies' to show inference, not just description, when analysing content.

Common mistakes to avoid

• Simply describing a source's content without analysing its provenance loses marks — always link content back to NOP.
• Do not say a source is 'good' or 'bad' — always say useful/reliable FOR a specific purpose.
• Do not ignore the caption/attribution — provenance details are almost always essential to the answer.
• For interpretation questions, do not just say 'they disagree because of bias' — explain the specific evidence or emphasis each historian uses.
• Always use short, exact quotations from the source(s) as supporting evidence, not vague paraphrases.
