President Obama’s remarks about the evil of the Crusades, needs to be factually examined in detail. Here is such a list:

0355 – After removing a Roman temple from the site (possibly the Temple of Aphrodite built by Hadrian), Constantine I has the Church of the Holy Sepulcher constructed in Jerusalem. Built around the excavated hill of the Crucifixion, legend has it that Constantine’s mother Helena discovered the True Cross here.

0613 – Persians capture Damascus and Antioch.

0614 – Persians sack Jerusalem. damaging the Church of the Holy Sepulcher in the process.

0635 – Muslims begin the conquest of Persia and Syria.

0635 – Arab Muslims capture the city of Damascus from the Byzantines.

August 20, 0636 – Battle of Yarmuk (also: Yarmuq, Hieromyax): Following the Muslim capture of Damascus and Edessa, Byzantine Emperor Heraclius organizes a large army which manages to take back control of those cities. However, Byzantine commander, Baänes is soundly defeated by Muslim forces under Khalid ibn Walid in a battle in the valley of the Yarmuk River outside Damascus. This leaves all of Syria open to Arab domination.

0637 – The Arabs occupy the Persian capital of Ctesiphon. By 0651, the entire Persian realm would come under the rule of Islam and continued its westward expansion.

0637 – Syria is conquered by Muslim forces.

0637 – Jerusalem falls to invading Muslim forces.

0638 – Caliph Umar I enters Jerusalem.

0639 – Muslims conquer Egypt and Persia.

0641 – Islam spreads into Egypt. The Catholic Archbishop invites Muslims to help free Egypt from Roman oppressors.

0641 – Under the leadership of Abd-al-Rahman, Muslims conquer southern areas of Azerbaijan, Daghestan, Georgia, and Armenia.

0641 – Under the leadership of Amr ibn al-As, Muslims conquer the Byzantine city of Alexandria in Egypt. Amr forbids the looting of the city and proclaims freedom of worship for all. According to some accounts, he also has what was left of the Great Library burned the following year. Al-As creates the first Muslim city in Egypt, al-Fustat, and builds there the first mosque in Egypt.

0644 – Muslim leader Umar dies and is succeeded by Caliph Uthman, a member of the Umayyad family that had rejected Muhammad’s prophesies. Rallies arise to support Ali, Muhammad’s cousin and son-in-law, as caliph. Uthman launches invasions to the west into North Africa.

0649 – Muawiya I, a member of the Umayyad family, leads a raid against Cyprus, sacking the capital Salamis-Constantia after a short siege and pillaging the rest of the island.

0652 – Sicily is attacked by Muslims coming out of Tunisia (named Ifriqiya by the Muslims, a name later given to the entire continent of Africa).

0653 – Muawiya I leads a raid against Rhodes, taking the remaining pieces of the Colossus of Rhodes (one of the Seven Wonders of the ancient world) and shipping it back to Syria to be sold as scrap metal.

0654 – Muawiya I conquers Cyprus and stations a large garrison there. The island would remain in Muslim hands until 0966.

0655 – Battle of the Masts: In one of the only Muslim naval victories in the entire history of Islam, Muslim forces under the command of Uthman bin Affan defeat Byzantine forces under Emperor Constant II. The battle takes place off the coast of Lycia and is an important stage in the decline of Byzantine power.

0661 – 0680 – Mu’awiya, founder of the Umayyad dynasty, becomes the caliph and moves the capital from Mecca to Damascus.

0662 – Egypt fell to the Umayyad and Abbasid caliphates until 868 CE. A year prior, the Fertile Crescent and Persia yielded to the Umayyad and Abbasid caliphates, whose rule lasted until 1258 CE and 820 CE, respectively.

0667 – Sicily is attacked by Muslims coming out of Tunisia.

0668 – First Siege of Constantinople: This attack lasts off and on for seven years, with the Muslim forces generally spending the winters on the island of Cyzicus, a few miles south of Constantinople, and only sailing against the city during the spring and summer months. The Greeks are able to fend off repeated attacks with a weapon desperately feared by the Arabs: Greek Fire. It burned through ships, shields, and flesh and it could not be put out once it started. Muawiyah has to send emissaries to Byzantine Emperor Constans to beg him to let the survivors return home unimpeded, a request that is granted in exchange for a yearly tribute of 3,000 pieces of gold, fifty slaves, and fifty Arab horses.

0669 – The Muslim conquest reaches to Morocco in North Africa. The region would be open to the rule of the Umayyad and Abbasid caliphates until 800 CE.

0672 – Muslims under Mauwiya I capture the island of Rhodes.

0674 – Arab conquest reaches the Indus River.

August 23, 0676 – Birth of Charles Martel (Charles the Hammer) in Herstal, Wallonia, Belgium, as the illegitimate son of Pippin II. Serving as Mayor of the Palace of the kingdom of the Franks, Charles would lead a force of Christians that turn back a Muslim raiding party near Poitiers (or Tours) which, according to many historians, would effectively halt the advance of Islam against Christianity in the West.

0677 – Muslims send a large fleet against Constantinople in an effort to finally break the city, but they are defeated so badly through the Byzantine use of Greek Fire that they are forced to pay an indemnity to the Emperor.

0680 – Birth of Leo III the Isaurian, Byzantine Emperor, along the Turkish-Syrian border in the Syrian province of Commagene. Leo’s tactical skills would be responsible for turning back the second Arab Muslim siege of Constantinople in 0717, shortly after he is elected emperor.

0688 – Emperor Justinian II and Caliph al-Malik sign a peace treaty making Cyprus neutral territory. For the next 300 years, Cyprus is ruled jointly by both the Byzantines and the Arabs despite the continuing warfare between them elsewhere.

0691 – Birth of Hisham, 10th caliph of the Umayyad Dynasty. It is under Hisham that Muslim forces would make their deepest incursions into Western Europe before being stopped by Charles Martel at the Battle of Poitiers in 0732.

0698 – Muslims capture Carthage in North Africa.

0700 – Muslims from Pamntelleria raid the island of Sicily.

0711 – With the further conquest of Egypt, Spain and North Africa, Islam included all of the Persian empire and most of the old Roman world under Islamic rule. Muslims began the conquest of Sindh in Afghanistan.

April 0711 – Tariq ibn Malik, a Berber officer, crosses the strait separating Africa and Europe with a group of Muslims and enters Spain (al-Andalus, as the Muslims called it, a word is etymologically linked to “Vandals”). The first stop in the Muslim conquest of Spain is at the foot of a mountain that comes to be called Jabel Tarik, the Mountain of Tarik. Today it is known as Gibraltar. At one time the Berbers had been Christians but they recently converted in large numbers to Islam after the Arab conquest of North Africa.

July 19, 0711 – Battle of Guadalete: Tariq ibn Ziyad kills King Rodrigo (or Roderic), Visigoth ruler of Spain, at the Guadalete River in the south of the Iberian peninsula. Tariq ibn Ziyad had landed at Gibraltar with 7,000 Muslims at the invitation of heirs of the late Visigoth King Witica (Witiza) who wanted to get rid of Rodrigo (this group includes Oppas, the bishop of Toledo and primate of all Spain, who happens to be the brother of the late king Witica). Ziyad, however, refuses to turn control of the region back over to the heirs of Witica. Almost the entire Iberian peninsula would come under Islamic control by 0718 CE.

0712 – Muslim governor of Northern Africa Musa ibn Nusayr follows Tariq ibn Ziyad with an army of 18,000 as reinforcements for the conquest of Andalusia. Musa’s father had been a Catholic Yemenite studying to be a priest in Iraq when he was captured in Iraq by Khalid, the “Sword of Islam,” and forced to choose between conversion or death. This invasion of Iraq had been one of the last military orders given by Muhammed before his death.

0714 – Birth of Pippin III (Pippin the Short) in Jupille (Belgium). Son of Charles Martel and father of Charlemagne, in 0759 Pippin would capture Narbonne, the last Muslim stronghold in France, and thereby drive Islam out of France.

0715 – By this year just about all of Spain is in Muslim hands. The Muslim conquest of Spain only took around three years but the Christian reconquest would require around 460 years (it might have gone faster had the various Christian kingdoms not been at each other’ throats much of the time). Musa’s son, Abd el-Aziz, is left in charge and makes his capital the city of Seville, where he married Egilona, widow of king Rodrigo. Caliph Suleiman, a paranoid ruler, would have el-Aziz assassinated and sends Musa into exile in his native Yemen village to live out his days as a beggar.

0716 – Lisbon is captured by Muslims.

0717 – Cordova (Qurtuba) becomes the capital of Muslim holdings in Andalusia (Spain).

0717 – Leo the Isaurian, born along the Turkish-Syrian border in the Syrian province of Commagene, revolts against the usurper Theodosius III and assumes the throne of the Byzantine Empire.

August 15, 0717 – Second Siege of Constantinople: Taking advantage of the civil unrest in the Byzantine Empire, Caliph Sulieman sends 120,000 Muslims under the command of his brother, Moslemah, to launch the second siege of Constantinople. Another force of around 100,000 Muslims with 1,800 galleys soon arrives from Syria and Egypt to assist. Most of these reinforcements are quickly destroyed with Greek Fire. Eventually the Muslims outside Constantinople begin to starve and, in the winter, they also begin to freeze to death. Even the Bulgarians, usually hostile to the Byzantines, send a force to destroy Muslim reinforcements marching from Adrianopolis.

August 15, 0718 – Muslims abandon their second siege of Constantinople. Their failure here leads to the weakening of the Umayyad government, in part because of the heavy losses. It is estimated that of the 200,000 soldiers who besieged Constantinople, only around 30,000 made it home. Although the Byzantine Empire also sustains heavily casualties and loses most its territory south of the Taurus Mountains, by holding the line here they prevent a disorganized and militarily inferior Europe from having to confront a Muslim invasion along the shortest possible route. Instead, the Arabic invasion of Europe must proceed along the longer path across northern Africa and into Spain, a route which prevents quick reinforcement and ultimately proves ineffective.

0719 – Muslims attack Septimania in southern France (so named because it was the base of operations for Rome’s Seventh Legion) and become established in the region known as Languedoc, made famous several hundred years later as the center of the Cathar heresy.

July 09,0721 – A Muslim army under the command of Al-Semah and that had crossed the Pyrenees is defeated by the Franks near Toulouse. Al-Semah is killed and his remaining forces, which had previously conquered Narbonne, are forced back across the Pyrenees into Spain.

0722 – Battle of Covadonga: Pelayo, (0690-0737) Visigoth noble who had been elected the first King of Asturias (0718- 0737), defeats a Muslim army at Alcama near Covadonga. This is generally regarded as the first real Christian victory over the Muslims in the Reconquista.

0724 – Hisham becomes the 10th caliph of the Umayyad Dynasty. It is under Hisham that Muslim forces make their deepest incursions into Western Europe before being stopped by Charles Martel at the Battle of Poitiers in 0732.

0724 – Under the command of Ambissa, Emir of Andalusia, Muslim forces raid southern France and capture the cities of Carcassone and Nimes. Primary targets in these and other raids are churches and monasteries where the Muslims take away holy objects and enslave or kill all the clerics.

0725 – Muslim forces occupied Nimes, France.

0730 – Muslim forces occupy the French cities of Narbonne and Avignon.

October 10, 0732 – Battle of Tours: With perhaps 1,500 soldiers, Charles Martel halts a Muslim force of around 40,000 to 60,000 cavalry under Abd el-Rahman Al Ghafiqi from moving farther into Europe. Many regard this battle as being decisive in that it saved Europe from Muslim control. Gibbon wrote: “A victorious line of march had been prolonged above a thousand miles from the rock of Gibraltar to the banks of the Loire; the repetition of an equal space would have carried the Saracens to the confines of Poland and the Highlands of Scotland; the Rhine is not more impassable than the Nile or Euphrates, and the Arabian fleet might have sailed without a naval combat into the mouth of the Thames. Perhaps the interpretation of the Koran would now be taught in the schools of Oxford, and her pulpits might demonstrate to a circumcised people the sanctity and truth of the revelation of Muhammed.” Others, though, argue that the battle’s importance has been exaggerated. The names of Tours, Poitiers, and Charles Martel do not appear in the Arab histories. They list the battle under the name Balat al- Shuhada, the Highway of Martyrs, and is treated as a minor engagement.

0735 – Muslim invaders capture the city of Arles.

0737 – Charles Martel sends his brother, Childebrand, to lay siege to Avignon and drive out the Muslim occupiers. Childebrand is successful and, according to records, has all the Muslims in the city killed.

0739 – Already having retaken Narbonne, Beziers, Montpellier, and Nimes during the previous couple of years, Childebrand captures Marseille, one of the largest French cities still in Muslim hands.

June 08, 0741 – Death of Leo III the Isaurian, Byzantine Emperor. Leo’s tactical skills were responsible for turning back the second Arab Muslim siege of Constantinople in 0717, shortly after he was elected emperor.

October 22, 0741 – Death of Charles Martel (Charles the Hammer) in at Quierzy (today the Aisne county in the Picardy region of France). As Mayor of the Palace of the kingdom of the Franks, Charles had led a force of Christians that turned back a Muslim raiding party near Poitiers (or Tours) which, according to many historians, effectively halted the advance of Islam against Christianity in the West.

April 04, 0742 – Birth of Charlemagne, founder of the Frankish Empire.

0743 – Death of Hisham, 10th caliph of the Umayyad Dynasty. It was under Hisham that Muslim forces made their deepest incursions into Western Europe before being stopped by Charles Martel at the Battle of Poitiers in 0732.

0750 – The Arabian Nights, a compilation of stories written under the reign of the Abbasids, became representative of the lifestyle and administration of this Persian influenced government.

0750 – 0850 – The Four Orthodox Schools of Islamic Law were established.

0750 – The Abbasids assume control of the Islamic world (except Spain, which falls under the control of a descendant of the Umayyad family) and moved the capital to Baghdad in Iraq. The Abbasid Caliphate would last until 1258.

0756 – The Emirate of Cordova is established by Umayyad refugee Abd al-Rahman I in order to revive the defeated Umayyad caliphate which had been destroyed in 0750 by the Abbasids. Cordova would become independent of the Abbasid Empire and represents the first major political division within Islam. The political and geographic isolation of the Cordova Caliphate would make it easier for Christians to decisively conquer it despite their failures elsewhere, although this would not be completed until 1492.

0759 – Arabs lose the city of Narbonne, France, their furthest and last conquest into Frankish territory. In capturing this city Pippin III (Pippin the Short) ends the Muslim incursions in France.

0768 – Pepin’s son, Carolus Magnus (Charlemagne), succeeded his father and became one of the most important European rulers of medieval history.

September 24, 0768 – Death of Pippin III (Pippin the Short) at Saint Denis. Son of Charles Martel and father of Charlemagne, in 0759 Pippin captured Narbonne, the last Muslim stronghold in France, and thereby drove Islam out of France.

0778 – Charlemagne, King of the Franks and soon-to-be Holy Roman Emperor, is invited by a group of Arab leaders in northeastern Spain to attack Abd al-Rahman I, ruler of the Emirate of Cordova. Charlemagne obliges them, but is forced to retreat after only getting as far as Saragossa. It is during his march back through the Pyrenees that his forces are set upon by Basques. Among the many who die is the war leader Roland from Breton, killed in Roncevalles, whose memory has been preserved in the “Chanson de Roland,” an important epic poem during the Middle Ages.

0831 – Muslim invaders capture the Sicilian city of Palermo and make it their capital.

0835 – Birth of Ahmad Ibn Tultun, founder of the Tulunid Dynasty in Egypt.

The Leonine Wall is built in order to fend off further attacks such as this.

0849 – Battle of Ostia: Aghlabid monarch Muhammad sends a fleet of ships from Sardinia to attack Rome. As the fleet prepares to land troops, the combination of a large storm and an alliance of Christian forces were able to destroy the Muslims ships.

0850 – The Acropolis of Zimbabwe was built in Rhodesia.

The two brothers were sent by the patriarch of Constantinople to Moravia, where the ruler, Rostilav, decreed in 863 that any preaching done had to be in the language of the people. As a result, Cyril and Methodius developed the first usable alphabet for the Slavic tongue – thus, the Cyrillic alphabet.

0866 – Emperor Louis II travels from Germany to southern Italy to battle the Muslim raiders causing trouble there.

0868 – The Sattarid dynasty, whose rule would continue until 0930 CE, extended Muslim control throughout most of Persia. In Egypt, the Abbasid and Umayyad caliphates ended and the Egyptian-based Tulunid dynasty took over (lasting until 904 CE).
