10th century in the context of "Adi Shankara"

Saeculum obscurum (Ecclesiastical Latin: [ˈsɛː.ku.lu.m obsˈkuː.rum], "the dark age/century"), also known as the Rule of the Harlots or the Pornocracy, was a period in the history of the papacy during the first two thirds of the 10th century, following the chaos after the death of Pope Formosus in 896, and the seven legitimate popes and one illegitimate antipope elected between 896 and 904. It began with the installation of Pope Sergius III in 904 and lasted for 60 years until the death of Pope John XII in 964. During this period, the popes were influenced strongly by a powerful and allegedly corrupt aristocratic family, the Theophylacti, and their relatives and allies. The era is seen as one of the lowest points of the history of the papal office.

The first millennium of the anno Domini or Common Era was a millennium spanning the years 1 to 1000 (1st to 10th centuries; in astronomy: JD 1721425.5 – 2086667.5). The world population rose more slowly than during the preceding millennium, from about 200 million in the year 1 to about 300 million in the year 1000.

In Western Eurasia (Europe and Near East), the first millennium was a time of great transition from Classical Antiquity to the Middle Ages. The 1st century saw the peak of the Roman Empire, followed by its gradual decline during the period of Late Antiquity, the rise of Christianity and the Great Migrations. The second half of the millennium is characterized as the Early Middle Ages in Europe, and marked by the Viking expansion in the west, and the continuation of the Byzantine Empire (Eastern Roman Empire) in the east.

The Anglo-Scottish border is a boundary in Great Britain that separates England and Scotland. It runs for 96 miles (154 km) between Marshall Meadows Bay on the east coast and the Solway Firth in the west.

The Firth of Forth was the border between the Picto-Gaelic Kingdom of Alba and the Anglian Kingdom of Northumbria in the early 10th century. It became the first Anglo-Scottish border with the annexation of Northumbria by Anglo-Saxon England in the mid-10th century. In 973, the Scottish king Kenneth II attended the English king Edgar the Peaceful at Edgar's council in Chester. After Kenneth had reportedly done homage, Edgar rewarded Kenneth by granting him Lothian. Despite this transaction, the control of Lothian was not finally settled and the region was taken by the Scots at the Battle of Carham in 1018 and the River Tweed became the de facto Anglo-Scottish border. The Solway–Tweed line was legally established in 1237 by the Treaty of York between England and Scotland. It remains the border today, with the exception of the Debatable Lands, north of Carlisle, and a small area around Berwick-upon-Tweed, which was taken by England in 1482. Berwick was not fully annexed into England until 1746, by the Wales and Berwick Act 1746.

New Persian (Persian: فارسی نو, romanized: fārsī-ye now), also known as Modern Persian (فارسی نوین) is the current stage of the Persian language spoken since the 8th to 9th centuries until now in Greater Iran and surroundings. It is conventionally divided into three stages: Early New Persian (8th/9th centuries), Classical Persian (10th–18th centuries), and Contemporary Persian (19th century to present).

Dari is a name given to the New Persian language since the 10th century, widely used in Arabic (see Istakhri, al-Maqdisi and ibn Hawqal) and Persian texts. Since 1964, Dari has been the official name in Afghanistan for the Persian spoken there.

Hogwarts School of Witchcraft and Wizardry (/ˈhɒɡwɔːrts/) is a fictional boarding school of magic in the Harry Potter series by J. K. Rowling. It is the primary setting for the first six novels and films and also serves as a major setting in the Wizarding World media franchise.

In the novels, Hogwarts is described as a coeducational, secondary boarding school that enrolls children from ages eleven to eighteen. According to Rowling, any child in Britain who shows magical ability is invited to attend the school. The Wizarding World website states that Hogwarts was founded in the Highlands of Scotland sometime between the 9th and 10th century by Godric Gryffindor, Helga Hufflepuff, Rowena Ravenclaw and Salazar Slytherin. Rowling has offered varying accounts of how many students are enrolled at Hogwarts at any given time.

1000 (M) was a leap year starting on Monday of the Julian calendar, the 1000th year of the Common Era (CE) and Anno Domini (AD) designations, the 1000th and last year of the 1st millennium, the 100th and last year of the 10th century, and the 1st year of the 1000s decade. As of the start of 1000, the Gregorian calendar was 5 days ahead of the Julian calendar, which was the dominant calendar of the time.

In the proleptic Gregorian calendar, it was a non-leap century year starting on Wednesday (like 1800).

The largest ethnic groups in Rwanda are the Hutus, which make up about 85% of Rwanda's population; the Tutsis, which are 14%; and the Twa, which are around 1%. Starting with the Tutsi feudal monarchy rule of the 10th century, the Hutus were a subjugated social group. Belgian colonization also contributed to the tensions between the Hutus and Tutsis. Hutu Power ideology propagated the myth that Hutus were the superior ethnicity. The resulting tensions would eventually foster the slaughtering of Tutsis in the Rwandan genocide. Since then, policy has changed to recognize one main ethnicity: "Rwandan".

In comparison to the Hutu (4.3% B), the Tutsi have three times as much haplogroup B (14.9% B), a haplogroup found at the highest rate in different African pygmies populations.
