Timeline of Events in the Middle Ages
180 The death of Roman emperor Marcus Aurelius marks the end of the "Pax Romana," or Roman peace. Years of instability follow, and although Rome recovers numerous times, this is the beginning of Rome's three-century decline.
312 Roman emperor Constantine converts to Christianity. As a result, the empire that once persecuted Christians will embrace their religion and eventually will begin to persecute other religions.
325 Constantine calls the Council of Nicaea, first of many ecumenical councils at which gatherings of bishops determine official church policy.
330 Constantine establishes Byzantium as eastern capital of the Roman Empire.

711 Arabs invade the Sind in western India, establishing a Muslim foothold on the Indian subcontinent.
727 In Greece, the Iconoclasts begin a sixty-year war on icons, or images of saints and other religious figures, which they consider idols. Though the Greek Orthodox Church ultimately rejects iconoclasm, the controversy helps widen a growing division between Eastern and Western Christianity.

1071 The Seljuk Turks defeat Byzantine forces at the Battle of Manzikert in Armenia. As a result, the Turks gain a foothold in Asia Minor (today known as Turkey), and the Byzantine Empire begins a long, slow decline.
1071 A Norman warlord named Robert Guiscard drives the last Byzantine forces out of Italy. Byzantium had controlled parts of the peninsula since the time of Justinian.
1072 Robert Guiscard's brother Roger expels the Arabs from Sicily, and takes control of the island.
1075–77 Pope Gregory VII and Holy Roman Emperor Henry IV become embroiled in a church-state struggle called the Investiture Controversy, a debate over whether popes or emperors should have the right to appoint local bishops. Deserted by his supporters, Henry stands barefoot in the snow for three days outside the gates of a castle in Canossa, Italy, waiting to beg the pope's forgiveness.
1084 Reversing the results of an earlier round in the Investiture Controversy, Henry IV takes Rome and forcibly removes Gregory VII from power. The pope dies soon afterward, broken and humiliated.

1094 Troops under the leadership of Rodrigo Díaz de Vivar—better known as El Cid —defeat the Moorish Almoravids at Valencia. This victory, and the character of El Cid himself, becomes a symbol of the Reconquista, the Christian effort to reclaim Spain from its Muslim conquerors.
1094 Norman warrior Bohemond, son of Robert Guiscard, takes control of Rome from Henry IV and hands the city over to Pope Urban II. Fearing the Normans' power and aware that he owes them a great debt, Urban looks for something to divert their attention.
1095 Byzantine Emperor Alexis Comnenus asks Urban II for military assistance against the Turks. Urban preaches a sermon to raise support at the Council of Clermont in France, and in the resulting fervor the First Crusade begins. Among its leaders are Bohemond and his nephew Tancred.
1096–97 A pathetic sideshow called the Peasants' Crusade plays out before the real First Crusade gets underway. The peasants begin by robbing and killing thousands of Jews in Germany; then, led by Peter the Hermit, they march toward the Holy Land, wreaking havoc as they go. In Anatolia, a local Turkish sultan leads them into a trap, and most of the peasants are killed.
1099 The First Crusade ends in victory for the Europeans as they conquer Jerusalem. It is a costly victory, however—one in which thousands of innocent Muslims, as well as many Europeans, have been brutally slaughtered—and it sows resentment between Muslims and Christians that remains strong today.
c. 1100–1300 Many of the aspects of life most commonly associated with the Middle Ages, including heraldry and chivalry, make their appearance in Western Europe during this period. Returning crusaders adapt the defensive architecture they observed in fortresses of the Holy Land, resulting in the familiar design of the medieval castle. This is also the era of romantic and heroic tales such as those of King Arthur.
1105 King Henry I of England and St. Anselm of Canterbury , head of the English church, sign an agreement settling their differences. This is an important milestone in church-state relations and serves as the model for the Concordat of Worms seventeen years later.

1146 After the Muslims' capture of Edessa in 1144, Pope Eugenius III calls on the help of his former teacher, Bernard of Clairvaux, who makes a speech that leads to the launching of the Second Crusade.
1147–49 In the disastrous Second Crusade, armies from Europe are double-crossed by their crusader allies in the Latin Kingdom of Jerusalem. They fail to recapture Edessa and suffer a heavy defeat at Damascus. Among the people who take part in the crusade (though not as a combatant) is Eleanor of Aquitaine.
1154 After the death of England's King Stephen, Henry II takes the throne, beginning the long Plantaganet dynasty. With Henry is his new bride, Eleanor of Aquitaine. Now queen of England, she had been queen of France two years earlier, before the annulment of her marriage to King Louis VII.
1158 Holy Roman Emperor Frederick I Barbarossa establishes Europe's first university at Bologna, Italy.

1165 A letter supposedly written by Prester John, a Christian monarch in the East, appears in Europe. Over the centuries that follow, Europeans will search in vain for Prester John, hoping for his aid in their war against Muslim forces. Even as Europe enters the modern era, early proponents of exploration such asHenry the Navigator will remain inspired by the quest for Prester John's kingdom.
1170 Knights loyal to Henry II murder the archbishop Thomas à Becket in his cathedral at Canterbury.
1174–80 Arab philosopher Averroës writes one of his most important works, The Incoherence of the Incoherence, a response to hard-line Muslim attacks on his belief that reason and religious faith can coexist.

1185 For the first time, Japan comes under the rule of a shogun, or military dictator. Shoguns will remain in power for the next four centuries.
1187 Muslim armies under Saladin deal the crusaders a devastating blow at the Battle of Hittin in Palestine. Shortly afterward, Saladin leads his armies in the reconquest of Jerusalem.
1189 In response to Saladin 's victories, Europeans launch the Third Crusade. Of the crusade's three principal leaders, Emperor Frederick I Barbarossa drowns on his way to the Holy Land, and Richard I takes a number of detours, only arriving in 1191. This leaves Philip II Augustus of France to fight the Muslims alone.
1192 Richard I signs a treaty with Saladin, ending the Third Crusade.
1198 Pope Innocent III begins an eighteen-year reign that marks the high point of the church's power. Despite his great influence, however, when he calls for a new crusade to the Holy Land, he gets little response—a sign that the spirit behind the Crusades is dying.
c. 1200 Cambodia's Khmer Empire reaches its height under Jayavarman VII.
1202 Four years after the initial plea from the pope, the Fourth Crusade begins. Instead of going to the Holy Land, however, the crusaders become involved in a power struggle for the Byzantine throne.

1215 English noblemen force King John to sign the Magna Carta, which grants much greater power to the nobility. Ultimately the agreement will lead to increased freedom for the people from the power of both king and nobles.
1217–21 In the Fifth Crusade, armies from England, Germany, Hungary, and Austria attempt unsuccessfully to conquer Egypt.
1228–29 The Sixth Crusade, led by Holy Roman Emperor Frederick II, results in a treaty that briefly restores Christian control of Jerusalem—and does so with a minimum of bloodshed.
1229 The brutal Albigensian Crusade ends. Not only are the Cathars destroyed, but so is much of the French nobility, thus greatly strengthening the power of the French king.

1260 Kublai Khan, greatest Mongol leader after his grandfather Genghis Khan, is declared Great Khan, or leader of the Mongols.
1261 Led by Michael VIII Palaeologus, the Byzantines recapture Constantinople from the Latin Empire, and Byzantium enjoys one last gasp of power before it goes into terminal decline.
1270–72 In the Ninth Crusade, last of the numbered crusades, King Louis IX of France again leads the Europeans against the Mamluks, who defeat European forces yet again.
1271 Marco Polo embarks on his celebrated journey to the East, which lasts twenty-four years.
1273 The Hapsburg dynasty—destined to remain a major factor in European politics until 1918—takes control of the Holy Roman Empire.
1273 Italian philosopher and theologian Thomas Aquinas completes the crowning work of his career, the monumental Summa theologica. The influential book will help lead to wider acceptance of the idea, introduced earlier by Moses Maimonides, Averroës, and Abelard, that reason and faith are compatible.
1279 Mongol forces under Kublai Khan win final victory over China's Sung dynasty. Thus begins the Yüan dynasty, the first time in Chinese history when the country has been ruled by foreigners.
