The 11th century
3,132 sourced entries across 100 documented years, grouped into 10 decades. A century here runs 1900–1999 rather than 1901–2000, so its decades sit inside it exactly; on the BC side the same rule puts 1–99 BC in the 1st century BC and 100 BC in the 2nd.

A few of the years
- 1000In Scandinavia, Christianization was in its early stages, with the Althing of the Icelandic Commonwealth embracing Christianity in the year 1000. On September 9, the King of Norway, Olaf Tryggvason, was defeated by the Scandinavian kingdoms of Denmark and Sweden in the Battle of Svolder. Sweyn Forkbeard established Danish control over part of Norway. The city of Oslo was founded in Norway (the exact year is debatable, but the 1,000 year anniversary was held in the year 2000). It is known that in or around this year, Norse explorer Leif Erikson became the first European to land in the Americas, at L'Anse aux Meadows in modern-day Newfoundland.
