A brief thread on the life, religion, and language of Omar ibn Sa’id, author of the only known Arabic-language autobiography of an enslaved person in the United States.

Buckle up, everyone, this story is *wild*.

The 62-year-old Dyatlov Pass mystery, in which nine students died at the hands of an unknown force, has likely been solved thanks to the movie Frozen and gruesome car crash experiments.

Me, for @NatGeo + thread!

In what has become known as the Dyatlov Pass incident, ten members of the Urals Polytechnic Institute in Yekaterinburg—nine students and one sports instructor who fought in World War II—headed into the frigid wilderness on a skiing expedition on January 23, 1959. 1/x

One student turned back after experiencing joint pain.

He never saw his friends again.

The team made camp on February 1, pitching a large tent on the snowy slopes of Kholat Saykhl, whose name can be interpreted as “Dead Mountain” in the language of the region’s Indigenous Mansi people. Ominous, sure - but these were experienced mountain hikers. 3/x

The nine were never heard from again.

When a search team arrived at Kholat Saykhl a few weeks later, the tent was found just barely sticking out of the snow, and it appeared cut open from the inside. The next day, the first of the bodies was found near a cedar tree. 4/x

In 1637, the Dutch Republic erupted into a speculative fever over an unlikely item...the tulip.

Tulip Mania has become a legend synonymous with market euphoria and bubbles. But is this tale all it's cracked up to be?

Who's up for a story?

👇👇👇

1/ The tulip is a spring-blooming flower native to the valleys of the Tien Shan Mountains in Central Asia.

It is believed to have been introduced to Europe in 1554, when an ambassador of the Holy Roman Emperor sent tulip bulbs and seeds to Vienna from the Ottoman Empire.

2/ Tulips gained in popularity as people were attracted to their rich color and ability to grow in sub-optimal conditions.

They soon became a coveted status symbol for the wealthy.

The Semper Augustus, with its colorful, flame-like streaks, was the most desired of them all.

3/ By the early 1600s, the Dutch Republic was entering a golden age.

Many financial innovations popped up during this time - the first stock exchange, for example.

But it was another financial innovation that would propel tulips into historical lore: the futures contract.

4/ As tulips grow slowly and may take several years to bloom, paper contracts were written that entitled the buyer to the future tulips.

These contracts were freely-traded.

So in addition to the physical market for tulip bulbs, a thriving paper market was established.

Today is Jayanti of Udham Singh, the man who assasinated General O Dwyer, responsible for the Jallianwala Bagh massacre and the atrocities that followed, a true hero.

His real name was Sher Singh, born on Dec 26, 1899, to a poor peasant family in Punjab’s Sangrur district. His father, Tehl Singh, worked as a railway gate keeper at a level crossing in the Uppali village of Punjab.

Having lost both his parents when he was small, he along with his brother Mukta Singh, grew up in the Central Khalsa Orphanage in Amritsar. Following the Sikh initiation rites, he got the name of Udham Singh.

In 1919, he left the orphanage after passing the matriculation exam. In that year Punjab was in turmoil, with massive protests breaking out against the British rule.

Around 1500 Indian civilians, in Amritsar, protesting against the deportation of nationalist leaders, Dr.Saifuddin Kitchlew and Satyapal Dang, were brutally massacred at Jallianwala Bagh in Amritsar. While Gen Dyer led the carnage, he was backed by the Lt. Governor O’Dwyer.

Why and how did the ancient Egyptians build pyramids?

Pyramids were built for religious purposes. The Egyptians were one of the first civilizations to believe in an afterlife. Most were built as tombs for the pharaohs and their consorts during the Old and Middle Kingdom periods.

Most accepted construction hypotheses are based on the idea that it was built by moving huge stones from a quarry and dragging and lifting them into place. There are three known chambers inside the Great Pyramid.

All the pyramids were built by Egyptian workers and Imhotep was the architect of the first pyramid and the Saqqara step pyramid. He also built the pyramid of Djoser’s successor, Sekhemkhet. He was later deified as the god of medicine throughout Egypt in the Late Period.

It is not known who designed the Great Pyramid, but the man responsible for supervising its complex construction was Hemiunu, Khufu’s nephew, a senior civil servant who acted as the pharaoh’s vizier.

Despite the mystery surrounding Giza, Hemiunu himself was a flesh-and-blood man, as shown by his decidedly lifelike—and fleshy—statue, found in his tomb in Giza’s west cemetery.

Mines had always had a large female element in their workforce; women were generally employed to carry coal to the surface. It was only in 1842 – with the Mines Regulation Act – that women and young children were banned from working below ground.

The following passage is an extract of a book that was published by Robert Bald, a mining engineer at Alloa, in 1812.

Robert Bald, A General View of the Coal Trade of Scotland, Chiefly that of the River Forth & Lothian, to which is Added an Inquiry into the Condition of the Women who Carry Coals under Ground in Scotland, Known by the Name of Bearers, Edinburgh: Oliphant, Waugh and Innes, 1812

In those collieries where this mode is in practice, the collier leaves his house for the pits about eleven o’clock at night, (attended by his sons, if he has any sufficiently old), when the rest of mankind are retiring to rest. Their first work is to prepare coals, by hewing

them down from the wall. In about three hours after, his wife (attended by her daughters, if she has any sufficiently grown) sets out for the pit, having previously wrapped her infant child in a blanket, and left it to the care of an old woman, who, for a small gratuity,
