24 August 410

A Gothic army commanded by Alaric entered Rome on 24 August 410, after repeated sieges and a final breakdown in negotiations with Honorius's government, and began three days of plunder.

Honorius was at Ravenna. Rome remained symbolically central but was no longer the emperor's regular residence.

Nobody agrees who opened the gate

Procopius, writing roughly a century and a half later, says 300 beardless Gothic youths entered Roman households disguised as enslaved servants, killed the guards at the Salarian Gate and admitted Alaric's army.

In the same passage he supplies an alternative: the wealthy matron Proba, pitying a famine-stricken population, ordered her own domestics to open the gates at night.

The manner of entry therefore cannot be stated as settled fact.

Three days, then out

Residents were killed, assaulted, robbed and taken captive — the imperial princess Galla Placidia among them — but the surviving partisan accounts supply no trustworthy totals.

Orosius, writing Christian apologetic history a few years afterward, says Alaric ordered that refugees in holy places be left unharmed, especially in the basilicas of Peter and Paul, and that his men restrain bloodshed while taking booty.

The army departed after three days rather than occupying the city. Procopius reports fires near the Salarian Gate, including damage to the House of Sallust; modern scholarship concludes Rome suffered a major psychological shock but comparatively limited physical damage.

13 February 528, a letter to the Senate

At Constantinople on 13 February 528, Justinian issued the constitution Haec quae necessario to the Senate, commissioning a new codex of imperial constitutions.

The commission was instructed to draw from the Gregorian, Hermogenian and Theodosian Codes, and from constitutions issued after them — including Justinian's own enactments.

Ten commissioners were named: John, Leontius, Phocas, Basilides, Thomas, Tribonian, Constantinus, Theophilus, Dioscorus and Praesentinus.

Licensed to edit

They were authorized to remove obsolete, repetitive or contradictory material; to add, delete or change words; to merge provisions; and to arrange the surviving enactments under appropriate titles.

Justinian stated the point in practical terms: a single clear collection for use in court, so that litigation would be shorter.

Not yet Tribonian's project, not yet the Corpus

Tribonian was one of ten here, not the director. The senior commissioner John is conventionally identified as John the Cappadocian and treated by modern accounts as head of this first Code commission.

The mandate covered the leges — the imperial constitutions — not the classical jurists' writings later assembled as the Digest, which was a separate and later undertaking.

The first Code was published on 7 April 529. It was itself replaced by the revised Code of 534 and has not survived independently.

Spring 542, in the capital

Procopius, who was present, reports that the epidemic reached Constantinople in the spring of 542, after appearing at Pelusium in Egypt and spreading through Egypt and Palestine.

Victims developed a sudden fever, followed within days by buboes in the groin, the armpit, beside the ears or on the thighs. Coma, delirium, tissue death and black pustules were among the reported complications.

Some sufferers became delirious and tried to throw themselves into the sea, forcing caregivers to restrain them.

When burial broke down

As ordinary funerals stopped functioning, Justinian assigned palace soldiers and money to an official named Theodorus, who took charge of the bodies families could no longer handle.

When the graves filled, workers removed the roofs from towers at Sycae across the Golden Horn, filled the interiors with bodies, and roofed them over.

Justinian caught the disease himself during the outbreak, and recovered.

The numbers are claims, not counts

Procopius says the outbreak ran four months in the city, at greatest virulence for about three, with 5,000 deaths a day at the peak and later 10,000 or more.

John of Ephesus reports that official counters abandoned their tally at 230,000 and that a single day reached 16,000 bodies. Scholars caution that ancient mortality figures may be exaggerated; the city's real death toll is unknown and sits at the center of an active debate.

Ancient DNA recovered from sixth-century victims confirms that Yersinia pestis caused the first plague pandemic — which is not the same as establishing how many died in Constantinople.

A secret march, then four columns

The TDV İslâm Ansiklopedisi treats 20 Ramadan 8 AH — conventionally 11 January 630 — as the generally accepted date; the date attached to this entry is off by eleven months. After marching secretly from Medina and camping at Marr al-Zahran with a force of roughly 10,000, Muhammad divided his troops for entry into Mecca and instructed the commanders to avoid fighting unless compelled. Abu Sufyan reached the camp and saw so many campfires that he compared them to the fires at Arafat.

Most columns met no organized resistance. Khalid ibn al-Walid’s defeated the one Meccan force that fought, near the Handama slopes — the principal combat of the takeover, with reported casualties of 12 or 28 Meccans and two or three Muslims.

At the sanctuary

Muhammad entered from the upper or northwestern side wearing a helmet rather than pilgrim dress, set his standard at al-Hajun and joined the other columns near Safa.

He then announced security for people sheltering in designated houses or the Sacred Mosque, those staying at home, and those laying down their weapons. The amnesty was broad but carried about ten named exceptions; the TDV encyclopedia says three were captured and killed, while others fled or were later pardoned.

Which date, and how bloodless

A hadith report says Muhammad struck the 360 cult images around the Kaaba with a stick; another says he ordered images removed from inside before entering the building. By the end of the operation Quraysh rule of Mecca had ended and the sanctuary was under his authority.

The early traditions differ on the entry date: 10, 17/18, 19 and 20 Ramadan 8 AH are all reported. Other calendar models place stages of the campaign in December 629.

A halt at the watering place of Khumm

Returning toward Medina after the Farewell Pilgrimage, Muhammad stopped at the watering place of Khumm, between Mecca and Medina, and addressed the pilgrims travelling with him. The day is fixed in the Islamic calendar — 18 Dhu al-Hijjah 10 AH — but the Common Era conversions disagree, putting it on 16, 17 or 18 March 632.

One transmitted version has him urge his listeners to hold fast to the Book of God and remind them of their obligations toward his household. Another widely transmitted report preserves the declaration: "For whomever I am his mawla, then Ali is his mawla."

The setting was not a mosque or a palace but a stop on the road, and the account reaches us through companions such as Zayd ibn Arqam rather than through a written record made that day.

Two sermons, two dates, one label

"Final sermon" is a label that collapses distinct addresses. The Farewell Sermon proper was delivered earlier, at Arafat during the pilgrimage; Ghadir Khumm came later, on the return journey, on 18 Dhu al-Hijjah 10 AH.

Converting 18 Dhu al-Hijjah into a Common Era day depends on lunar-calendar reconstruction and on whether one uses the Julian or the proleptic Gregorian convention. Encyclopaedia Iranica settles on 16 March; other modern conversions yield 17 or 18 March.

The listed "March 18" may simply be the eighteenth day of Dhu al-Hijjah read as a civil-calendar date.

What mawla was taken to mean

Mawla carries several senses — patron, master, protector, close associate — and the interpretation is the central Sunni–Shia dispute over the episode. Shia tradition reads the declaration as investing Ali with authority over the community.

Many Sunni authorities preserve the same report while declining to read it as a political appointment. The sources record a memorable public statement of Ali's standing; they do not document a transfer of government that day.

The declaration is commemorated as Eid al-Ghadir.

Four scribes and a borrowed manuscript

Around 651, in the standard account preserved in Sahih al-Bukhari, Hudhayfa ibn al-Yaman returned from the northern campaigns alarmed at disagreements over recitation and urged Caliph Uthman to act before the community divided over its scripture.

Uthman borrowed the manuscript sheets held by Hafsa and appointed Zayd ibn Thabit with three Qurayshi collaborators — Abd Allah ibn al-Zubayr, Saʿid ibn al-As and Abd al-Rahman ibn al-Harith — to copy them into codices, with disagreements to be resolved in the language of Quraysh.

Copies went to every province; other Qur'anic materials were ordered burned. Hafsa's sheets were not among them — the report says they were returned to her.

Around 651, give or take a few years

The Bukhari account supplies no year. Nicolai Sinai links its northern campaign to AH 30, which is 650–651, and the Metropolitan Museum uses 651.

So the listed 651 is a reasonable point estimate rather than a documented date, and no day at all is recoverable.

Manuscript evidence supports the general picture without dating it: comparative study finds that nearly all known Qur'anic manuscripts descend from a single written archetype, and shared irregular spellings across regions work like fingerprints pointing back to it.

What "modern-day form" overstates

The Uthmanic codex fixed a consonantal skeleton — the letters, word order, verse and surah order across 114 surahs — not the dotted, vowelled page of a modern printed Qur'an.

Standardizing the written skeleton did not eliminate accepted recitational variation.

Nor was this a first collection from nothing. Islamic tradition distinguishes an earlier collection under Abu Bakr from Uthman's copying and distribution, and the lower text of the Sanaa palimpsest shows that an alternative early text type existed.

The wind finally turns

William, Duke of Normandy, had been waiting in the Somme estuary for weather he could use. In the conventional reconstruction a favourable southerly arrived on 27 September 1066 and he ordered his fleet out of Saint-Valery-sur-Somme toward England.

A hydrographic study of the crossing allows either 27 or 28 September for the departure. An estimated 700 ships made the passage overnight.

Dawn at Pevensey

In the usual modern reconstruction the fleet entered Pevensey Bay before dawn on 28 September and the army disembarked unopposed. Harold II was in northern England, three days past his victory over Harald Hardrada and Tostig at Stamford Bridge.

The Normans immediately threw up a temporary fortification to protect the troops and the beachhead. English Heritage places it almost certainly inside the walls of the Roman fort.

Why the chroniclers disagree

The Anglo-Saxon Chronicle's recensions conflict: version D puts William at Pevensey on Michaelmas Eve, 28 September; version E gives Hastings on Michaelmas Day, 29 September. These are Julian dates kept by historical convention, corresponding to 3–4 October in the proleptic Gregorian calendar.

The best-supported reconstruction has William marching his army the roughly ten miles from Pevensey to Hastings the following day, rather than sailing there as one main force.

December 1066: Wallingford, then Berkhamsted

In early December 1066 William crossed the Thames at Wallingford, where Archbishop Stigand met him and submitted. He had not marched straight on London — resistance at Southwark forced a wide movement west and an approach from the north.

At Berkhamsted, Archbishop Ealdred, Edgar Ætheling, Earls Edwin and Morcar and London's leading men submitted, provided hostages and swore oaths.

The Anglo-Saxon Chronicle says William promised to govern them well, even as his troops went on plundering the country they crossed.

Christmas Day at Westminster

On 25 December, Archbishop Ealdred of York crowned William king in Westminster Abbey, according to the established English rite. Stigand attended but did not perform it.

Ealdred presented the new king to the English-speaking congregation and Geoffrey of Coutances to the French-speaking one. When both acclaimed him, Norman guards outside took the noise for an attack and set nearby houses alight.

Smoke and panic emptied much of the church. William and the clergy completed the rite regardless.

Not the end of anything

By Christmas night William had oaths and hostages from leading opponents and London under his authority. Control of the whole kingdom still took years of campaigning, and major rebellions followed.

The Dover and Canterbury stages belong to October and November rather than December; documentary tradition gives William eight days strengthening Dover's defenses.

The great stone keep visible at Dover today is chiefly Henry II's twelfth-century rebuilding, not William's 1066 work.

4 July 1187, at the Horns of Hattin

Saladin's Ayyubid army defeated the field army led by Guy of Lusignan, king of Jerusalem, near the Horns of Hattin west of the Sea of Galilee on 4 July 1187.

The Frankish army had left the springs at Saffuriya the previous day to relieve besieged Tiberias. Harassment, a waterless campsite and the heat left it thirsty and disordered before the main fighting began.

Saladin's troops burned dry brush so that smoke and heat compounded the thirst.

The army comes apart

The Frankish infantry and cavalry became separated. Raymond III of Tripoli's vanguard broke through the encirclement and escaped; Guy, the leading nobles and most of the remaining army were killed or captured.

The march was not simply a king taking obvious bait. Abandoning Tiberias risked losing a major fortress and marching risked water deprivation, and recent scholarship explicitly reassesses the older story that Guy was merely foolish or cowardly.

What Saladin took

His forces captured the relic of the True Cross that had served as the kingdom's battle standard.

Guy was spared as a royal prisoner. Raynald of Châtillon — whose caravan raids and truce violations had made him a particular target — was killed with Saladin's participation or on his order, though accounts differ over who delivered the fatal blow.

A contemporary Christian account says virtually every man fit for war had been called out of the kingdom's cities and castles before the army was destroyed.

Friday, 2 October 1187 — not 20 September

Balian of Ibelin surrendered Jerusalem to Saladin on Friday 2 October 1187 — 27 Rajab 583 — after negotiating safe conduct for inhabitants who paid ransom.

The 20 September date marks the siege's opening in a common Latin chronology; medieval sources place Saladin's arrival between 18 and 21 September. From the conventional start to the surrender is twelve days, not a month.

The surrender fell on 27 Rajab, the anniversary associated with Muhammad's Night Journey, giving the date unusual symbolic weight for the victors.

Negotiated at the point of a breach

Mangonels, archers and sappers had opened a substantial breach in the northeastern wall, and the defenders could not close it.

Balian warned that a final assault would leave the defenders fighting to the death, destroying property and Muslim holy places and killing the Muslim prisoners held inside. That threat reaches us through medieval narrative sources and should be attributed rather than quoted.

Ransom, not amnesty

Ransomed Latins were allowed to depart with their movable possessions; those who could not pay faced enslavement. The Latin Libellus gives ten bezants for each male aged ten or over, five per female and one per young boy; an Arabic-source synthesis gives ten dinars, five and two, payable within forty days.

Imad al-Din says Balian offered 30,000 dinars on behalf of the poor, and further groups were released without payment — 700 at the patriarch's request, 500 at Balian's and 1,000 at al-Adil's.

Muslim prisoners in the city were released, and Saladin's administration began restoring the Dome of the Rock and al-Aqsa Mosque to Muslim worship.

The mountain that became a lake, 1257

Mount Samalas on Lombok erupted in 1257 through several phases: at least two Plinian fallout phases, an intervening water-influenced phreatoplinian phase, and voluminous pyroclastic-density currents produced when the eruption column collapsed.

The eruption destroyed the upper Samalas cone and formed the Segara Anak caldera. The pre-eruption summit has been reconstructed at about 4,200 metres above sea level.

How far the deposits reach

Ash blanketed Lombok and is preserved on Bali and Sumbawa; the deposit geometry also indicates fallout in eastern Java. That evidence shows ashfall on Sumbawa, not pyroclastic flows crossing the sea to it.

Pyroclastic-current deposits remain as much as 35 metres thick 25 kilometres from the caldera.

Estimates put the erupted magma at 40.2 ± 3 km³ dense-rock equivalent and the initial plume at 43 ± 8.6 km above sea level, classing the eruption at VEI 7.

A capital named in a chronicle, never located

Later Lombok chronicles say the eruption destroyed Pamatan, capital of the Lombok kingdom. Pamatan has not been archaeologically located, and the textual account remains only partly corroborated.

The Babad Lombok preserves social memory rather than eyewitness manuscripts; the versions modern researchers examined were probably compiled in the eighteenth or nineteenth century.

The year is supported by radiocarbon modelling, polar ice-core chemistry, historical climate evidence and the Lombok tradition — but no exact day survives, and the westward ash pattern only suggests the dry season, roughly May to October.

3 September 1260, northern Palestine

The Egyptian Mamluk army led by Sultan Qutuz met Kitbuqa's Mongol-led force at ʿAyn Jālūt on 3 September 1260. Sources variously equate the day with 25 or 26 Ramadan 658 AH.

The fighting initially went badly for part of the Mamluk army. Qutuz personally rallied the shaken troops, and the Mamluks ultimately broke the opposing force.

Kitbuqa's end, told two ways

Kitbuqa was killed or captured and then executed — the sources differ over the precise sequence — and his army was decisively defeated.

Hülegü was not on the field. He had withdrawn the main army from Syria and left Kitbuqa a command originally assigned as one tümen, nominally about 10,000 troops, which is not a secure count of the men actually present.

Syria empties out

Surviving Mongol troops and officials withdrew from Syria after the defeat. Damascus's population expelled the Mongol garrison, and Mamluk forces rapidly occupied territory extending to the Euphrates.

The medieval sources do not permit reliable casualty totals or a secure strength for either army, and scholars stress that Kitbuqa commanded a reduced force rather than an enormous host.

This was not the Mongols' first battlefield defeat — Jalal al-Din had inflicted a serious one at Parwan in 1221 — and it did not end Mongol activity in Syria, where Ilkhanid invasions and frontier warfare continued for decades.
