Middle Ages

The Byzantine Empire, also known as the Eastern Roman Empire, was the continuation of the Roman Empire centred on Constantinople during late antiquity and the Middle Ages. Having survived the events that caused the fall of the Western Roman Empire in the 5th century AD, it endured until the fall of Constantinople to the Ottoman Empire in 1453. The term 'Byzantine Empire' was coined only after its demise; its citizens used the term 'Roman Empire' and called themselves 'Romans'.

During the early centuries of the Roman Empire, the western provinces were Latinised, but the eastern parts kept their Hellenistic culture. Constantine I (r. 324–337) legalised Christianity and moved the capital to Constantinople. Theodosius I (r. 379–395) made Christianity the state religion and Greek gradually replaced Latin for official use. The empire adopted a defensive strategy and, throughout its remaining history, experienced recurring cycles of decline and recovery.

The Ecumenical Patriarch of Constantinople (Greek: Οἰκουμενικός Πατριάρχης, romanized: Oikoumenikós Patriárchēs) is the archbishop of Constantinople and primus inter pares (first among equals) among the heads of the several autocephalous churches that comprise the Eastern Orthodox Church. The ecumenical patriarch is regarded as the representative and spiritual leader of the Eastern Orthodox Christians worldwide. The term ecumenical in the title is a historical reference to the Ecumene, a Greek designation for the civilised world, i.e. the Roman Empire, and it stems from Canon 28 of the Council of Chalcedon.

The patriarch's see, the Ecumenical Patriarchate of Constantinople, is one of the most enduring institutions in the world and has had a prominent part in world history. The ecumenical patriarchs in ancient times helped in the spread of Christianity and the resolution of various doctrinal disputes. In the Middle Ages, they played a major role in the affairs of the Eastern Orthodox Church, as well as in the politics of the Orthodox world, and in spreading Christianity among the Slavs. Currently, in addition to the expansion of the Christian faith and the Eastern Orthodox doctrine, the patriarchs are involved in ecumenism and interfaith dialogue, charitable work, and the defense of Orthodox Christian traditions.

Ireland is an island in the North Atlantic Ocean, in Northwestern Europe. Geopolitically, the island is divided between the Republic of Ireland (officially named Ireland – a sovereign state covering five-sixths of the island) and Northern Ireland (part of the United Kingdom – covering the remaining sixth). It is separated from Great Britain to its east by the North Channel, the Irish Sea, and St George's Channel. Ireland is the second-largest island of the British Isles, the third-largest in Europe, and the twentieth-largest in the world. As of 2022, the population of the entire island is just over 7 million, with 5.1 million in the Republic of Ireland and 1.9 million in Northern Ireland, ranking it the second-most populous island in Europe after Great Britain.

The geography of Ireland comprises relatively low-lying mountains surrounding a central plain, with several navigable rivers extending inland. Much of Ireland was woodland until the end of the Middle Ages. Today, woodland makes up about 10% of the island, compared with a European average of over 33%, with most of it being non-native conifer plantations. Its lush vegetation is a product of its mild climate, which is influenced by the Atlantic Ocean and thus very moderate, and winters are milder than expected for such a northerly area, although summers are cooler than those in continental Europe. Rainfall and cloud cover are abundant.

Many undeciphered writing systems exist today; most date back several thousand years, although some more modern examples do exist. The term "writing systems" is used here loosely to refer to groups of glyphs which appear to have representational symbolic meaning, but which may include "systems" that are largely artistic in nature and are thus not examples of actual writing.

The difficulty in deciphering these systems can arise from a lack of known language descendants or from the languages being entirely isolated, from insufficient examples of text having been found and even (such as in the case of Vinča) from the question of whether the symbols actually constitute a writing system at all. Some researchers have claimed to be able to decipher certain writing systems, such as those of Epi-Olmec, Phaistos and Indus texts; but to date, these claims have not been widely accepted within the scientific community, or confirmed by independent researchers, for the writing systems listed here (unless otherwise specified).

Ancient Greek philosophy arose in the 6th century BC. Philosophy was used to make sense of the world using reason. It dealt with a wide variety of subjects, including astronomy, epistemology, mathematics, political philosophy, ethics, metaphysics, ontology, logic, biology, rhetoric and aesthetics. Greek philosophy continued throughout the Hellenistic period and later evolved into Roman philosophy.

Greek philosophy has influenced much of Western culture since its inception, and can be found in many aspects of public education. Alfred North Whitehead once claimed: "The safest general characterization of the European philosophical tradition is that it consists of a series of footnotes to Plato". Clear, unbroken lines of influence lead from ancient Greek and Hellenistic philosophers to Roman philosophy, early Islamic philosophy, medieval scholasticism, the European Renaissance and the Age of Enlightenment.

In world history, post-classical history refers to the period from about 500 CE to about 1450 or 1500 CE, roughly corresponding to the European Middle Ages following the decline of the western Roman Empire. The post-classical period is characterized by the expansion of certain civilizations geographically, by ongoing wars fought over land, resources and religion, and by the development of trade networks between often-distant civilizations. This period is also called—with various implications and emphases—the medieval era, the post-antiquity era, the post-ancient era, or the pre-modern era.

In Asia and the Middle East during this time, the spread of Islam helped produce a series of caliphates which fostered the Islamic Golden Age, leading to advances in science and greater trade between those in the Asian, African, and European continents. East Asia experienced the entrenchment of the power of a unitary and Imperial China, the dynastic governance and culture of which influenced Japan, Korea and Vietnam. Religions such as Buddhism and neo-Confucianism spread in the region, while Christianity became entrenched in Europe and increasingly elsewhere. Gunpowder was developed in China during the post-classical era. The Mongol Empire conquered and controlled much of Europe and Asia, permitting more trade and cultural and intellectual exchange between the two regions.

Latin literature includes the essays, histories, poems, plays, and other writings written in the Latin language. The beginning of formal Latin literature dates to 240 BC, when the first stage play in Latin was performed in Rome. Latin literature flourished for the next six centuries. The classical era of Latin literature can be roughly divided into several periods: early Latin literature, the golden age, the imperial period and Late Antiquity.

Latin was the language of the ancient Romans as well as being the lingua franca of Western and Central Europe throughout the Middle Ages. Latin literature features the work of Roman authors, such as Cicero, Virgil, Ovid and Horace, but also includes the work of European writers after the fall of the Empire, from religious writers like Aquinas (1225–1274) to secular writers like Francis Bacon (1561–1626), Baruch Spinoza (1632–1677), and Isaac Newton (1642–1727).

The modern era or the modern period is considered the current historical period of human history. It was originally applied to the history of Europe and Western history for events that came after the Classical antiquity and the Middle Ages, often from around the year 1500, like the Reformation in Germany giving rise to Protestantism. Since the 1990s, it has been more common among historians to refer to the period after the Middle Ages and up to the 19th century as the early modern period. The modern period is today more often used for events from the 19th century until today. The time from the end of World War II (1945) can also be described as being part of contemporary history. The common definition of the modern period today is often associated with events like the French Revolution, the Industrial Revolution, and the transition from nationalism toward the liberal international order.

The modern period has been a period of significant development in the fields of science, politics, warfare, and technology. It has also been an Age of Discovery and globalization. During this time, the European powers and later their colonies, strengthened their political, economic, and cultural colonization of the rest of the world. It also created a new modern lifestyle and has permanently changed the way people around the world live.

Publius Ovidius Naso (Latin: [ˈpuːbliʊs ɔˈwɪdiʊs ˈnaːsoː]; 20 March 43 BC – AD 17/18), known in English as Ovid (/ˈɒvɪd/ OV-id), was a Roman poet who lived during the reign of Augustus. He was a younger contemporary of Virgil and Horace, with whom he is often ranked as one of the three canonical poets of Latin literature. The Imperial scholar Quintilian considered him the last of the Latin love elegists. Although Ovid enjoyed enormous popularity during his lifetime, the emperor Augustus exiled him to Tomis, the capital of the newly organised province of Moesia, on the Black Sea, where he remained for the last nine or ten years of his life. Ovid himself attributed his banishment to a carmen et error ("poem and a mistake"), but his reluctance to disclose specifics has resulted in much speculation among scholars.

Ovid is most famous for the Metamorphoses, a continuous mythological narrative in fifteen books written in dactylic hexameters. He is also known for works in elegiac couplets such as Ars Amatoria ("The Art of Love") and Fasti. His poetry was much imitated during Late Antiquity and the Middle Ages, and greatly influenced Western art and literature. The Metamorphoses remains one of the most important sources of classical mythology today.

Narrative poetry is a form of poetry that tells a story, often using the voices of both a narrator and characters; the entire story is usually written in metered verse. Narrative poems do not need to rhyme. The poems that make up this genre may be short or long, and the story it relates to may be complex. It is normally dramatic, with various characters. Narrative poems include all epic poetry, and the various types of "lay", most ballads, and some idylls, as well as many poems not falling into a distinct type.

Some narrative poetry takes the form of a novel in verse. An example of this is The Ring and the Book by Robert Browning. In terms of narrative poetry, romance is a narrative poem that tells a story of chivalry. Examples include the Romance of the Rose or Tennyson's Idylls of the King. Although those examples use medieval and Arthurian materials, romances may also tell stories from classical mythology. Sometimes, these short narratives are collected into interrelated groups, as with Chaucer's The Canterbury Tales. So sagas include both incidental poetry and the biographies of poets.
