c. 1168 Maimonides sets out the Thirteen Principles of Faith 0 cit. In his commentary on the Mishnah, Moses Maimonides, known as the Rambam, defined thirteen principles he held to be the core beliefs of Judaism, including a strictly non-corporeal God.

At Blois in France in 1171 more than thirty Jews were burned on a blood libel accusation, though no body was ever found.

Popes and some rulers condemned the libel as false, but it kept returning for centuries. politics / religion / society ●●

1171 Henry II and the Lordship of Ireland 0 cit. Alarmed by Strongbow's success, King Henry II of England landed in 1171 to bring the Norman lords and Irish kings under his authority. He took the title Lord of Ireland, a claim the papacy had earlier endorsed. English control was real near Dublin but thin elsewhere, and over later centuries many Norman families became, as the saying went, more Irish than the Irish themselves. politics / war ●●

c. 1175 Zhu Xi and Neo-Confucianism 0 cit. The scholar Zhu Xi synthesized Confucian, Buddhist, and Daoist ideas into a new philosophical system. Neo-Confucianism became the orthodox framework for later Chinese education and examinations. culture / religion ●●●●

1179 The Church bars Christian usury and pushes Jews into moneylending 0 cit. The Third Lateran Council and later canon law forbade Christians from lending money at interest, which the Church called the sin of usury. Barred from most guilds, from owning land, and from many trades, some Jews filled the gap as moneylenders, a role rulers allowed because they could tax it heavily. The debts that resulted bred resentment among Christian borrowers. Historians stress the niche was forced on Jews by exclusion, not chosen out of any group trait. economy / religion / society ●●

1179 The Church forbids Christians to lend at interest 0 cit. The Third Lateran Council rules that Christians who lend money at interest are guilty of the sin of usury and may be denied a Christian burial. Because canon law barred Christians from the trade but did not bind Jews in the same way, rulers and townspeople increasingly turned to Jewish lenders for credit. This is the documented root of the medieval association of Jews with moneylending. economy / religion ●●●

1179 to 1215 The Lateran Councils impose the Jewish badge and segregation 0 cit. The Third Lateran Council of 1179 and the Fourth Lateran Council of 1215, both summoned by the papacy, tightened restrictions on Jewish life across Western Christendom. The Fourth Lateran under Innocent III required Jews and Muslims to wear distinguishing dress or a badge, barred them from public office, and ordered them to stay indoors during Holy Week.

c. 1180 Aaron of Lincoln, financier to the English crown 0 cit. Aaron of Lincoln became one of the wealthiest financiers in England, lending to abbeys, nobles, and the crown for building projects. When he died in 1186 the king seized his estate and set up a special treasury branch just to collect the debts owed to him. His fortune shows the real scale a few Jewish lenders could reach, but also how completely that wealth depended on a king who could take it at will. economy / politics ●●

1181 The Assize of Arms sets the duty to bear arms for defence 0 cit. Henry II's Assize of Arms required free men to keep weapons and armour matched to their wealth and to answer a muster in defence of the realm.

Eggs, forbidden through Lent and a natural symbol of new life and of the sealed tomb from which Christ rose, become the Easter egg; decorated and gifted eggs are recorded across medieval Europe. Older spring-fertility associations with the egg fold naturally into the Christian meaning. culture / religion ●●●

c. 1200 The Inca establish themselves at Cusco 0 cit. According to Inca oral tradition, a founding lineage settles the valley of Cusco and builds it into a small highland kingdom. For its first centuries it is one of many rival Andean polities rather than a great power. The early chronology rests on later Spanish accounts of Inca oral history and is uncertain. politics / society ●

c. 1200 The rock-hewn churches of Lalibela 0 cit. Under the Zagwe king Lalibela, eleven churches were cut downward out of solid volcanic rock, each carved as a single piece with windows, columns, and drainage channels.

Many Kalenjin groups link these remains to their ancestors, though scholars debate how directly the Sirikwa connect to any single present-day community. society / technology ●●

1202 Fibonacci brings Hindu-Arabic numerals to Europe 0 cit. Leonardo of Pisa, called Fibonacci, learned Hindu-Arabic numerals from Muslim merchants in North Africa and argued for them in his book Liber Abaci. The new digits with their zero made calculation far easier than Roman numerals, though cities were slow to trust them and some banned them for a time. He did not invent the famous rabbit-breeding sequence, which was known earlier in India, but his book carried it into European mathematics. economy / science ●●●●

13 April 1204 The Fourth Crusade sacks Constantinople 0 cit. A crusade meant for the Holy Land was diverted and turned on the Christian city of Constantinople, which the crusaders looted and burned.

15 June 1215 Magna Carta limits the power of the English king 0 cit. Rebellious barons force King John to seal Magna Carta, which states that the king cannot tax or imprison freemen at will and must act within the law.

1215 The Fourth Lateran Council orders Jews to wear distinguishing marks 0 cit. The Fourth Lateran Council, called by Pope Innocent III, required Jews and Muslims to wear distinguishing clothing or badges so Christians would not mix with them unknowingly.

c. 1250 The reality of small-scale Jewish lending 0 cit. Most Jewish lenders were not great financiers but small operators making modest loans against pledged goods, often to neighbors and local farmers. They had little power to force repayment, depended on royal courts to collect debts, and could be ruined when a king cancelled debts or taxed them heavily. The picture of the all-powerful Jewish moneylender is a later invention that ignores how exposed and dependent these lenders actually were. economy / society ●●

c. 1250 The Lombards and Cahorsins, Christendom's Christian lenders 0 cit. Christian financiers from Lombardy and Cahors ran large lending and pawnbroking operations across Europe, often outweighing Jewish lenders in scale.

c. 1250 Jews prosper, then decline, under Christian rule 0 cit. In the Christian kingdoms of the thirteenth century Jews served kings as physicians, tax collectors, financiers, and translators, and Sephardic learning continued.

c. 1250 The Great Interregnum leaves the throne contested 0 cit. After the Hohenstaufen dynasty collapsed, rival and often absent claimants held the imperial title while no one ruled effectively.

The Palaiologan dynasty would rule a shrinking realm for its final two centuries. politics / war ●●

1263 The Disputation of Barcelona 0 cit. King James I of Aragon summoned the scholar Nachmanides to a public disputation with the convert Pablo Christiani over whether Jewish texts proved Jesus was the messiah.

c. 1275 Rulers tax the Jews as a royal sponge, then expel them 0 cit. English kings treated Jews as royal property and taxed them through heavy levies called tallages until the community was drained of wealth. Once the Jews could no longer yield revenue, expelling them let the crown cancel its own duty to protect them and seize outstanding debts and assets. Historians describe the method as squeezing a sponge dry and then throwing it away. The 1290 expulsion followed decades of this fiscal exploitation. economy / politics / society ●●
