Super awwsome guidline:
THE BLACK DEATH (1347–1351)
ORIGINS & SPREAD:
Originated in Central Asia (probably China or Mongolia)
Spread westward along the Silk Road
Arrived in Europe through the port of Messina, Sicily in 1347 via Genoese trade ships
Spread rapidly through trade routes, port cities, and pilgrim paths
CAUSES:
Caused by the bacterium Yersinia pestis
Carried by fleas → which lived on black rats → which lived aboard ships and in cities
Three forms of plague:
Bubonic: swollen lymph nodes (buboes) in groin, armpits, neck
Pneumonic: airborne, affected lungs; spread from person to person
Septicemic: infected bloodstream; most deadly
SYMPTOMS:
High fever, chills, vomiting, fatigue
Buboes (painful swellings)
Black patches (internal bleeding)
Coughing blood (pneumonic)
Death often in 3–5 days
WHY IT SPREAD SO QUICKLY:
Crowded and dirty medieval towns
No sanitation or garbage control
Fleas and lice thrived in unwashed clothing and bedding
Close living quarters + trade + war = perfect storm
Medical knowledge was primitive and misunderstood the disease
FAILED TREATMENTS:
Lancing buboes: caused infections, spread bacteria
Leeching & bloodletting: weakened the sick even more
Burning incense and carrying flowers: thought to ward off “bad air”
Flagellants: whipped themselves in public to atone for sins
Plague doctors: wore bird-beaked masks filled with herbs; totally ineffective
WHO ESCAPED & WHY:
Poland: Largely spared thanks to King Casimir III’s quarantine laws
Quarantined all newcomers for 3–4 days — enough time to show symptoms and die
Milan: Walled up infected houses early
Rumors: Cats ate plague rats (might’ve helped); but in many places, cats were killed for being “evil,” which made rat populations worse
DEATH TOLL:
Europe: 25–50 million people (1/3 to 1/2 of the population)
Global: Possibly over 100 million deaths
CONSEQUENCES:
1. SOCIAL:
Collapse of feudalism
Serfs and peasants could demand higher wages
Peasants left manors and moved to cities
Rise of the middle class and merchants
2. RELIGIOUS:
People lost faith in the Church (clergy died too, prayers didn’t work)
Rise in antisemitism: Jews accused of poisoning wells
Massacres and forced conversions followed
3. ECONOMIC:
Labor shortages
Farmland abandoned
Wages rose for survivors
Trade routes disrupted and rerouted
WHAT TO MEMORIZE:
1347–1351: Years of the Black Death in Europe
Bacteria: Yersinia pestis
Poland and Milan’s quarantine strategies
Why lancing didn’t work: infections, spread germs
Types of plague: bubonic, pneumonic, septicemic
Impact: death toll, fall of feudalism, weakened Church, rise of middle class
⚔ THE CRUSADES (1095–1291)
WHAT?
A series of religious wars between Christians and Muslims
Purpose: reclaim Jerusalem and the Holy Land
Ordered by popes, fought by knights and peasants
MAJOR DATES & EVENTS
1095: Pope Urban II calls for the First Crusade at the Council of Clermont
1096–1099: First Crusade – captures Jerusalem
1147–1149: Second Crusade – fails
1189–1192: Third Crusade – ends in a truce between Saladin and Richard the Lionheart
1202–1204: Fourth Crusade – Crusaders sack Constantinople (Christian city)
1212: Children’s Crusade – thousands of kids die or are sold into slavery
1291: Muslims retake Acre – marks the end of the Crusader states
WHY PEOPLE WENT:
Religious: Forgiveness of sins, ticket to Heaven
Social: Peasants and younger sons had no land; wanted opportunity
Political: Pope wanted to unite European kingdoms and gain power
Economic: Land, plunder, and trade opportunities
WHO FOUGHT:
European knights, lords, peasants
Peter the Hermit: led the failed People’s Crusade
Saladin: great Muslim general, recaptured Jerusalem in 1187
Richard the Lionheart: English king, skilled military leader
Pope Urban II: called the First Crusade
RESULTS:
SHORT TERM:
Only the First Crusade was fully successful
New contact with Muslim world: trade goods, ideas, science
Byzantines temporarily aided, but later betrayed (Constantinople sacked)
LONG TERM:
Trade between Europe and the Middle East increased
Ancient knowledge (Greek, Arabic, science, math, medicine) flowed into Europe
Feudalism weakened: many nobles died, kings grew stronger
Sparked growth of cities and the Renaissance
Worsened Christian-Muslim relations (and Catholic-Orthodox tensions)
Rise in antisemitism during crusading fervor
CHAIN OF EVENTS:
Pope calls Crusade
Christians go to Holy Land
War causes contact with Islamic world
Trade and knowledge increase
Ideas flow back into Europe
Cities and universities grow
Renaissance begins
MEMORIZE:
Dates of Crusades: especially First (1096–99), Third (1189–92), and Fourth (1202–04)
Important people: Pope Urban II, Saladin, Richard the Lionheart, Peter the Hermit
Key effects: increase in trade and knowledge, weakening of feudalism, rise of Renaissance
🛡 THE CRUSADES
🗓 Date
First Crusade: 1096–1099
