As a means of recording the passage of time, the 11th century is the period from 1001 to 1100 in accordance with the Julian calendar in the Christian Era. In the history of European culture, this period is considered the early part of the High Middle Ages. There was a sudden decline of Byzantine power and rise of Norman domination over much of Europe, along with the prominent role in Europe of notably influential popes. In what is now Northern Italy, a growth of population in urban centers gave rise to early organized capitalism and more sophisticated, commercialized culture by the late 11th century. In Song China and the Islamic world, this century marked the high point for both classical Chinese civilization, science, and technology and medieval Islamic science, technology, and literature. Rivaling political factions at the Song Dynasty court created strife amongst the leading statesmen and ministers of the empire. There was also a population explosion, doubling to the size of 100 million, and an economic revolution in China that spurred manufacture and production rates which rivaled even Great Britain's coal and iron output in the early Industrial Revolution. For Chola-era India and Fatimid-era Egypt, they had reached their zenith in military might and international influence. The Western Chalukya Empire (the Chola's rival) also rose to power by the end of the century. In this century the Turkish Seljuk dynasty comes to power in the Middle East over the now fragmented Abbasid realm, while the first of the Crusades were waged towards the close of the century. In Japan the Fujiwara clan continued to dominate the affairs of state. In the Americas the Toltec and Mixtec civilizations flourished in central America, along with the Huari Culture of South America and the Mississippian culture of North America. In Russia, there was the golden age for the principality of Kievan Rus. In Korea the Goryeo Kingdom flourished and faced external threats from the Liao Dynasty ( Manchuria). In Vietnam the Lý Dynasty began, while in Myanmar the Pagan Kingdom reached its height of political and military power.

In European history, the 11th century is regarded as the beginning of the High Middle Ages, an age subsequent to the Early Middle Ages. The century began while the translatio imperii of 962 was still somewhat novel and ended in the midst of the Investiture Controversy. It saw the final Christianisation of Scandinavia and the emergence of the Peace and Truce of God movements, the Gregorian Reforms, and the Crusades which revitalised a church and a papacy that had survived tarnished by the tumultuous tenth century. In 1054, the Great Schism rent the church in two, however.

In Germany, it was marked by the ascendancy of the Holy Roman Emperors, who hit their high watermark under the Salians.

In Italy, it opened with the integration of the kingdom into the empire and the royal palace at Pavia was sacked in 1024. By the end of the century, Lombard and Byzantine rule in the Mezzogiorno had been usurped by the Normans and the power of the territorial magnates was being replaced by that of the citizens of the cities in the north.

In Britain, it saw the transformation of Scotland into a single, more unified and centralised kingdom and the Norman conquest of England in 1066. The social transformations wrought in these lands brought them into the fuller orbit of European feudal politics.

In France, it saw the nadir of the monarchy and the zenith of the great magnates, especially the dukes of Aquitaine and Normandy, who could thus foster such distinctive contributions of their lands as the pious warrior who conquered Britain, Italy, and the East and the impious peacelover, the troubadour, who crafted out of the European vernacular its first great literary themes. There were also the first figures of the intellectual movement known as Scholasticism, which emphasized dialectic arguments in disputes of Christian theology as well as classical philosopy.

In Spain, the century opened with the successes of the last caliphs of Córdoba and ended in the successes of the Almoravids. In between was a period of Christian unification under Navarrese hegemony and success in the Reconquista against the taifa kingdoms which replaced the fallen caliphate.

In China, there was a triangular affair of continued war and peace settlements between the Song Dynasty, the Tanguts-led Western Xia in the northwest, and the Khitans of the Liao Dynasty in the northeast. Meanwhile, opposing political factions evolved at the Song imperial court of Kaifeng. The political reformers at court, called the New Policies Group (新法, Xin Fa), were led by Emperor Shenzong of Song and the Chancellors Fan Zhongyan and Wang Anshi, while the political conservatives were led by Chancellor Sima Guang and Empress Dowager Gao, regent of the young Emperor Zhezong of Song. Heated political debate and sectarian intrigue followed, while political enemies were often dismissed from the capital to govern frontier regions in the deep south where malaria was known to be very fatal to northern Chinese people (see History of the Song Dynasty). This period also represents a high point in classical Chinese science and technology, with figures such as Su Song and Shen Kuo, as well as the age where the matured form of the Chinese pagoda was accomplished in Chinese architecture.

In India, the Chola Dynasty reached its height of naval power under leaders such as Rajaraja Chola I and Rajendra Chola I, dominating southern India ( Tamil Nadu), Sri Lanka, and regions of South East Asia. They also sent raids into what is now modern-day Thailand.

In Japan, the Fujiwara clan dominated central politics by acting as imperial regents, controlling the actions of the Emperor of Japan, who acted merely as a ' puppet monarch' during the Heian period.

In the Middle East, the Fatimid Empire reached its zenith only to face steep decline, much like the Byzantine Empire in the first half of the century. The Seljuks came to prominence while the Abbasid caliphs held traditional titles without real, tangible authority in state affairs.

In Korea, the rulers of the Goryeo Kingdom were able to concentrate more central authority into their own hands than in that of the nobles, and were able to fend off two Khitan invasions with their armies.
