11th century in the context of "Otto I, Duke of Bavaria"

Italy, up until its unification in 1861, was a conglomeration of city-states, republics, and other independent entities. The following is a list of the various Italian states during that period. Following the fall of the Western Roman Empire and the arrival of the Middle Ages (in particular from the 11th century), the Italian Peninsula was divided into numerous states. Many of these states consolidated into major political units that balanced the power on the Italian Peninsula: the Papal States, the Venetian Republic, the Republic of Florence, the Duchy of Milan, the Kingdom of Naples and the Kingdom of Sicily. Unlike all the other Italian states of the medieval and early modern period, the republics of Venice and Genoa, thanks to their maritime power, went beyond territorial conquests within the Italian Peninsula, conquering various regions across the Mediterranean and Black Seas.

Adi Shankara (8th c. CE), also called Adi Shankaracharya (Sanskrit: आदि शङ्कर, आदि शङ्कराचार्य, romanized: Ādi Śaṅkara, Ādi Śaṅkarācārya, lit. 'First Shankaracharya', pronounced [aːd̪i ɕɐŋkɐraːt͡ɕaːrjɐ]), was an Indian Vedic scholar, philosopher and teacher (acharya) of Advaita Vedanta. While he is often revered as the most important Indian philosopher, reliable information on Shankara's actual life is scant, and the historical influence of his works on Hindu intellectual thought has been questioned. The historical Shankara was probably relatively unknown and Vaishna-oriented. His true impact lies in his "iconic representation of Hindu religion and culture," despite the fact that most Hindus do not adhere to Advaita Vedanta.

Until the 10th century Shankara was overshadowed by his older contemporary Maṇḍana Miśra, and there is no mention of him in concurrent Hindu, Buddhist or Jain sources until the 11th century. The legendary Shankara was created in the 14th century, centuries after his death, when Sringeri matha started to receive patronage from the emperors of the Vijayanagara Empire and shifted their allegiance from Advaitic Agamic Shaivism to Brahmanical Advaita orthodoxy. Hagiographies dating from the 14th-17th centuries deified him as a ruler-renunciate, travelling on a digvijaya (conquest of the four quarters) across the Indian subcontinent to propagate his philosophy, defeating his opponents in theological debates. These hagiographies portray him as founding four mathas (monasteries), and Adi Shankara also came to be regarded as the organiser of the Dashanami monastic order, and the unifier of the Shanmata tradition of worship. The title of Shankaracharya, used by heads of certain monasteries in India, is derived from his name. Tradition also portrays him as the one who reconciled the various sects (Vaishnavism, Shaivism, and Shaktism) with the introduction of the Pañcāyatana form of worship, the simultaneous worship of five deities – Ganesha, Surya, Vishnu, Shiva and Devi, arguing that all deities were but different forms of the one Brahman, the invisible Supreme Being.

Inverness (/ˌɪnvərˈnɛs/ ; Scots: Innerness; from the Scottish Gaelic: Inbhir Nis [iɲɪɾʲˈniʃ], meaning "Mouth of the River Ness") is a city in the Scottish Highlands, having been granted city status in 2000. It is the administrative centre for The Highland Council and is regarded as the capital of the Highlands.

Historically it served as the county town of the county of Inverness-shire. Inverness lies near two important battle sites: the 11th-century battle of Blàr nam Fèinne against Norway which took place on the Aird, and the 18th century Battle of Culloden which took place on Culloden Moor. It is the northernmost city in the United Kingdom and lies within the Great Glen (Gleann Mòr) at its north-eastern extremity where the River Ness enters the Beauly Firth.

The second millennium of the Anno Domini or Common Era was a millennium spanning the years 1001 to 2000. It began on January 1, 1001 (MI) and ended on December 31, 2000 (MM), (11th to 20th centuries; in astronomy: JD 2086667.5 – 2451909.5).

It encompassed the High and Late Middle Ages of the Old World, the Islamic Golden Age and the period of Renaissance, followed by the early modern period, characterized by the European wars of religion, the Age of Enlightenment, the Age of Discovery and the colonial period. Its final two centuries coincide with modern history, characterized by industrialization, the rise of nation states, the rapid development of science, widespread education, and universal health care and vaccinations in the developed world. The 20th century saw increasing globalization, most notably the two World Wars and the subsequent formation of the United Nations. 20th-century technology includes powered flight, television and semiconductor technology, including integrated circuits. The term "Great Divergence" was coined to refer the unprecedented cultural and political ascent of the Western world in the second half of the millennium, emerging by the 18th century as the most powerful and wealthy world civilization, having eclipsed Qing China, Edo Japan, the Islamic world and India. This allowed the colonization by European countries of much of the world during this millennium, including the Americas, Africa, Oceania, and South and Southeast Asia.

Catholic Church sexual abuse cases in Canada are well documented dating back to the 1960s. The preponderance of criminal cases with Canadian Catholic dioceses named as defendants that have surfaced since the 1980s strongly indicate that these cases were far more widespread than previously believed. While recent media reports have centred on Newfoundland dioceses, there have been reported cases—tested in court with criminal convictions—in almost all Canadian provinces. Sexual assault is the act of an individual touching another individual sexually and/or committing sexual activities forcefully and/or without the other person's consent. The phrase Catholic sexual abuse cases refers to acts of sexual abuse, typically child sexual abuse, by members of authority in the Catholic church, such as priests. Such cases have been occurring sporadically since the 11th century in Catholic churches around the world. This article summarizes some of the most notable Catholic sexual abuse cases in Canadian provinces.

The Venetian–Genoese Wars were four conflicts between the Republic of Venice and the Republic of Genoa which took place between 1256 and 1381. Each was resolved almost entirely through naval clashes, and they were connected to each other by interludes during which episodes of piracy and violence between the two Italian trading communities in the Mediterranean Sea and the Black Sea were commonplace, in a "cold war" climate.

Starting in the 11th century, Venice and Genoa had built commercial empires which, in the 13th century, became thalassocracies so solid as to oust the other maritime republics and to make the two cities privileged interlocutors of state structures such as the Byzantine Empire, the Kingdom of Hungary, etc. In the second half of the 13th century the tensions between Venice and Genoa, exacerbated by the Venetian control over Constantinople following the Fourth Crusade, exploded. The first conflict, known as the War of Saint Sabas (1256-1270), was a Venetian victory, though it did not undermine the growing Genoese power in Constantinople and the Black Sea. The second conflict (1294-1299) recorded a revenge for the Ligurians, with significant military victories. After a temporary alliance against the Mongols during the siege of Caffa (1346), Venice and Genoa clashed again in the War of the Straits (1350-1355), during which Venice dragged in the Kingdom of Aragon, Genoa's emerging Tyrrhenian rival. This third war again ended in stalemate with a Genoese military victory at great cost. The fourth conflict, the War of Chioggia (1377-1381), saw Venice surrounded by various fronts, with the Genoese reaching the entrance to the Venetian Lagoon, but, with an enormous war effort, Venice achieved the final victory, saving the city from destruction, even without a debilitating economic outlay. Acts of piracy between the Venetians and Genoese (subject to French control in the meantime) continued until the Venetian victory at the Battle of Modon (1403). Thirty years later, the two republics faced each other again in the Battle of San Fruttuoso (1431), but in the context of the Wars in Lombardy and with Genoa then subject to the Visconti of Milan.
