In the [proleptic Gregorian calendar](/source/proleptic_Gregorian_calendar), it was a [non-leap century year starting on Wednesday](/source/common_year_starting_on_Wednesday) (like [1800](/source/1800)).

The year falls well into the period of [Old World](/source/Old_World) history known as the [Middle Ages](/source/Middle_Ages); in Europe, it is sometimes and by convention considered the boundary date between the [Early Middle Ages](/source/Early_Middle_Ages) and the [High Middle Ages](/source/High_Middle_Ages). The [Muslim world](/source/Muslim_world) was in its [Islamic Golden Age](/source/Islamic_Golden_Age). China was in its [Song dynasty](/source/Song_dynasty), Korea was in its [Goryeo dynasty](/source/Goryeo), Vietnam was in its [Anterior Lê dynasty](/source/Anterior_L%C3%AA_dynasty) and Japan was in its classical [Heian period](/source/Heian_period). India was divided into a number of [lesser empires](/source/Middle_kingdoms_of_India), such as the [Eastern Chalukyas](/source/Eastern_Chalukyas), [Pala Empire](/source/Pala_Empire) ([Kamboja Pala dynasty](/source/Kamboja_Pala_dynasty); [Mahipala](/source/Mahipala)), [Chola dynasty](/source/Chola_dynasty) ([Rajaraja I](/source/Rajaraja_I)), [Yadava dynasty](/source/Seuna_(Yadava)_dynasty), etc. [Sub-Saharan Africa](/source/Sub-Saharan_Africa) had developing urban centers and empires such as the Ghana Empire of the Wagadu, and the [Trans-Saharan slave trade](/source/Trans-Saharan_slave_trade) was beginning to be an important factor in the formation of the [Sahelian kingdoms](/source/Sahelian_kingdoms). The [pre-Columbian](/source/Pre-Columbian_era) [New World](/source/New_World) was in a time of general transition in many regions. [Wari](/source/Wari_culture) and [Tiwanaku](/source/Tiwanaku) cultures receded in power and influence while [Chachapoya](/source/Chachapoya_culture) and [Chimú](/source/Chimor) cultures rose to prominence in South America. In [Mesoamerica](/source/Mesoamerica), the [Maya](/source/Maya_peoples) [Terminal Classic](/source/Mesoamerican_chronology) period saw the decline of many grand polities of the [Petén](/source/Pet%C3%A9n_Basin) like [Palenque](/source/Palenque) and [Tikal](/source/Tikal) yet a renewed vigor and greater construction phases of sites in the [Yucatán Peninsula](/source/Yucat%C3%A1n_Peninsula) like [Chichen Itza](/source/Chichen_Itza) and [Uxmal](/source/Uxmal). [Mitla](/source/Mitla), with Mixtec influence, became the more important site of the Zapotec, overshadowing the waning [Monte Albán](/source/Monte_Alb%C3%A1n). [Cholula](/source/Cholula_(Mesoamerican_site)) flourished in central Mexico, as did [Tula](/source/Tula_(Mesoamerican_site)), the center of [Toltec](/source/Toltec) culture.

The [World population](/source/World_population) is estimated to have been between c. 250 and 310 million.<ref>310 million:  United Nations Department of Economic and Social Affairs, Population Division. 254 million:  Jean-Noël Biraben, 1980, "An Essay Concerning Mankind's Evolution", Population, Selected Papers, Vol. 4, pp. 1–13.</ref>

[[File:Europe 1000.jpg|thumb|270px|upright|[Western Europe](/source/Western_Europe), the [Holy Roman Empire](/source/Holy_Roman_Empire), [Kievan Rus'](/source/Kievan_Rus'), and the [Byzantine Empire](/source/Byzantine_Empire) in the [Middle Ages](/source/Middle_Ages) (year 1000)]]

* In [continental Europe](/source/continental_Europe), the [Holy Roman Empire](/source/Holy_Roman_Empire) established itself as the most powerful state. The Holy Roman Emperor [Otto III](/source/Otto_III%2C_Holy_Roman_Emperor) made a pilgrimage from [Rome](/source/Rome) to [Aachen](/source/Aachen) and [Gniezno](/source/Gniezno) ([Gnesen](/source/Gnesen)), stopping at [Regensburg](/source/Regensburg), [Meissen](/source/Meissen), [Magdeburg](/source/Magdeburg), and Gniezno. The [Congress of Gniezno](/source/Congress_of_Gniezno) (with [Bolesław I the Brave](/source/Boles%C5%82aw_I_the_Brave)) was part of his [pilgrimage](/source/Christian_pilgrimage). In Rome, he built the basilica of [San Bartolomeo all'Isola](/source/San_Bartolomeo_all'Isola), to host the relics of [St. Bartholomew](/source/Bartholomew_the_Apostle).
* In the [Kingdom of France](/source/Kingdom_of_France), [Robert II](/source/Robert_II_of_France), the son of [Hugh Capet](/source/Hugh_Capet), was the first King of the [Capetian royal dynasty](/source/House_of_Capet). 
* The [Byzantine Empire under the Macedonian dynasty](/source/Byzantine_Empire_under_the_Macedonian_dynasty) was engaged in a [long and hard war](/source/Byzantine_conquest_of_Bulgaria) with the [First Bulgarian Empire](/source/First_Bulgarian_Empire). The Byzantine generals, [Theodorokanos](/source/Theodorokanos) and [Nikephoros Xiphias](/source/Nikephoros_Xiphias) captured the former Bulgarian capitals of [Pliska](/source/Pliska) and [Great Preslav](/source/Great_Preslav), along with [Little Preslav](/source/Little_Preslav), extending Byzantine control over the northeastern portion of the Bulgarian state ([Mysia](/source/Mysia) and [Scythia Minor](/source/Scythia_Minor)). At the same time, Byzantium was instrumental in the [Christianization of Kievan Rus'](/source/Christianization_of_Kievan_Rus') and of other medieval confederations of Slavic states.
* In [Great Britain](/source/Great_Britain), a unified [Kingdom of England](/source/Kingdom_of_England) had developed out of the various [Anglo-Saxon kingdoms](/source/Anglo-Saxon_kingdoms).
* In [Scandinavia](/source/Scandinavia), [Christianization](/source/Christianization_of_Scandinavia) was in its early stages, with the [Althing](/source/Althing) of the [Icelandic Commonwealth](/source/Icelandic_Commonwealth) embracing Christianity in the year 1000. On [September 9](/source/September_9), the [King of Norway](/source/Monarchy_of_Norway), [Olaf Tryggvason](/source/Olaf_Tryggvason), was defeated by the Scandinavian kingdoms of [Denmark](/source/Kingdom_of_Denmark_(Middle_Ages)) and [Sweden](/source/Kingdom_of_Sweden_(Middle_Ages)) in the [Battle of Svolder](/source/Battle_of_Svolder). [Sweyn Forkbeard](/source/Sweyn_Forkbeard) established Danish control over part of [Norway](/source/Norway). The city of [Oslo](/source/Oslo) was founded in Norway (the exact year is debatable, but the 1,000 year anniversary was held in the year [2000](/source/2000)). It is known that in or around this year, [Norse](/source/Norsemen) explorer [Leif Erikson](/source/Leif_Erikson) became [the first European to land in the Americas](/source/Norse_colonization_of_North_America), at [L'Anse aux Meadows](/source/L'Anse_aux_Meadows) in modern-day [Newfoundland](/source/Newfoundland_and_Labrador).
* The [papacy](/source/History_of_the_papacy) during this time was in a period of decline, in retrospect known as the ''[saeculum obscurum](/source/saeculum_obscurum)'' ("Dark Age") or "pornocracy" ("rule of harlots"), a state of affairs that would result in the [Great Schism](/source/East%E2%80%93West_Schism) between [Roman Catholicism](/source/Catholic_Church) and [Eastern Orthodoxy](/source/Eastern_Orthodoxy) later in the 11th century.
* The [Kingdom of Hungary](/source/Kingdom_of_Hungary) was established in 1000 as a Christian state. In the next centuries, the Kingdom of Hungary became the pre-eminent cultural power in the Central European region. On [December 25](/source/December_25), [Stephen I](/source/Stephen_I_of_Hungary) was crowned as the first King of Hungary in [Esztergom](/source/Esztergom).
* [Sancho III of Pamplona](/source/Sancho_III_of_Pamplona) became King of [Aragon](/source/List_of_Aragonese_monarchs) and [Navarre](/source/List_of_Navarrese_monarchs). The [Reconquista](/source/Reconquista) was gaining some ground, but the southern Iberian peninsula would still be dominated by Islam for centuries to come; [Córdoba](/source/C%C3%B3rdoba%2C_Spain)  was the world's largest city at this time, with 450,000 inhabitants.
* In the [Kingdom of Croatia](/source/Kingdom_of_Croatia_(925%E2%80%931102)) the army of the [Republic of Venice](/source/Republic_of_Venice) led by Doge [Pietro II Orseolo](/source/Pietro_II_Orseolo) [conquered the island of Lastovo](/source/Siege_of_Lastovo).
* The [Château de Goulaine](/source/Ch%C3%A2teau_de_Goulaine) [vineyard](/source/vineyard) was founded in [France](/source/Kingdom_of_France). 
* The [archdiocese](/source/Roman_Catholic_Archdiocese_of_Gniezno) in [Gniezno](/source/Gniezno) was founded; the first [archbishop](/source/List_of_archbishops_of_Gniezno_and_primates_of_Poland) was [Radim Gaudentius](/source/Radim_Gaudentius), from [Slavník dynasty](/source/Slavn%C3%ADk_dynasty), and dioceses in [Kołobrzeg](/source/Ko%C5%82obrzeg), [Kraków](/source/Krak%C3%B3w) and [Wrocław](/source/Wroc%C5%82aw). 
* The [Bell foundry](/source/Bell_foundry) was founded in [Italy](/source/Italy) by [Pontificia Fonderia Marinelli](/source/Pontificia_Fonderia_Marinelli).

=== Islamic world ===
The [Muslim world](/source/Muslim_world) was in its [Golden Age](/source/Islamic_Golden_Age); still organised in [caliphate](/source/caliphate)s, it continued to be dominated by the [Abbasid Caliphate](/source/Abbasid_Caliphate), with the [Caliphate of Córdoba](/source/Caliphate_of_C%C3%B3rdoba) to the west, the [Fatimid Caliphate](/source/Fatimid_Caliphate) in North Africa, and experienced ongoing [campaigns](/source/Early_Muslim_conquests) [in Africa](/source/Islamization_of_the_Sudan_region) and [in India](/source/Muslim_conquests_in_the_Indian_subcontinent). At the time, [Persia](/source/History_of_Iran) was in a period of instability, with various polities seceding from  Abbasid rule, among whom the [Ghaznavids](/source/Ghaznavids) would emerge as the most powerful.

The Islamic world was reaching the peak of its historical [scientific achievements](/source/Science_in_the_medieval_Islamic_world). Important scholars and scientists who flourished in AD 1000 include [Al-Zahrawi](/source/Al-Zahrawi) (Abcasis), [Ibn Yunus](/source/Ibn_Yunus) (publishes his astronomical treatise ''Al-Zij al-Hakimi al-Kabir'' in [Cairo](/source/Cairo) in c. 1000), [Abu Sahl al-Quhi](/source/Abu_Sahl_al-Quhi) (Kuhi), [Abu-Mahmud Khujandi](/source/Abu-Mahmud_Khujandi), [Abu Nasr Mansur](/source/Abu_Nasr_Mansur), [Abu al-Wafa' al-Buzjani](/source/Abu_al-Wafa'_al-Buzjani), [Ahmad ibn Fadlan](/source/Ahmad_ibn_Fadlan), [Ali Ibn Isa](/source/Ali_ibn_Isa_al-Asturlabi), [Al-Karaji](/source/Al-Karaji) (al-Karkhi), [Ibn al-Haytham](/source/Ibn_al-Haytham) (''[Book of Optics](/source/Book_of_Optics)''), [Avicenna](/source/Avicenna), [Averroes](/source/Averroes), and [Al-Biruni](/source/Al-Biruni).

By this time, the [Turkic migration](/source/Turkic_migration) from the [Eurasian Steppe](/source/Eurasian_Steppe) had reached Eastern Europe, and most of the [Turkic tribes](/source/Turkic_peoples) ([Khazars](/source/Khazars), [Bulgars](/source/Bulgars), [Pechenegs](/source/Pechenegs) etc.) had been [Islamized](/source/Spread_of_Islam).
