5. They Were First People To Build And Use Artificial Dockyard
Lothal was one of the most remarkable cities of Indus valley civilization, which was located in modern state of Gujarat. Lothal was a well planned town, engineers and planners engaged themselves to protect the town from consistent floods right from the beginning. They ended up dividing the town into 1-2 meters high blocks each serving more than 20 houses. Now, that clearly indicate that their engineers had the skills required to develop something modern as dockyard. Lothal engineers placed high priority on building a dockyard and a warehouse to serve the purposes of trade
In 1954, archaeologists discovered the world’s earliest known evidence of building and using an artificial dockyard in Lothal, which must have connected the city with the ancient course of Sabarmati river. The dock was build on the eastern flank of the town, and is regarded by archaeologists and historians as an engineering feat of highest order.
4. They Developed Most Precise Measurement Techniques of Its Time
The people of Indus valley civilization developed techniques and tools to measure the length, weight and time with impressively high accuracy. They were even among the first homo-sapiens to use uniform measures such as length, time and weight. A sharp study of objects found in Indus territories indicate a large scale variation. Their smallest division which is marked on an ivory found in Gujarat was approximately 1.7mm, that’s the smallest division ever recorded on any scale of bronze age. But historians speculate that the engineers may have used the decimal subdivisions with the accuracy of 0.005 of an inch. They even used decimal subdivisions for the measurement of mass as revealed by their hexahedron weights. Their weight chart was in the ratio of 5:2:1 with weights ranging from 0.05 to 500 units, with each unit weighting approximately 28 grams, similar to English imperial ounce or Greek uncia.
3. They Had World’s First Dentist
You may think of dentistry to be a quite modern medical practice, but it’s pretty old, in fact it’s probably more than 7000 years old. People of Indus valley civilization practiced it in early Harappan period.
In 2001, while archaeologists were studying remains of two men in Mehrgarh, Pakistan which was the part of Indus valley civilization, proposed that people from early Harappan period perhaps had the knowledge of proto-dentistry. Later in 2006, archaeologists finally confirmed that the earliest known evidence of drilling a living person teeth is found in Mehrgarh, from the age of Indus valley civilization.
Eleven drilled molar crowns from nine different adults were discovered in Neolithic graveyard in Mehrgarh, that are believed to be 7,500 to 9,000 years old.
2. Indus Valley civilization Was Almost Heaven
Indus valley civilization was located on a plain of Indus river which at its time was arguably the best place on earth to have a civilization. There was no lack of food for any person of the civilization. At its peak Indus valley may have had the population of 5 million people, that doesn’t sound much in 21st century but it was a great achievement 5000 years ago.
One of the best quality (or weakness) of Indus valley civilization is that they were peace loving people. Despite archaeologists finding more than 1050 sites and settlements there were very little or no sign of warfare, murder or use of weaponry. Their nonviolent nature is completely contrast to a contemporary civilization Ancient Egypt, whose leaders always had urge to conquer neighborhood lands and engage in war with others.
Indus valley civilization had extremely peaceful and progressive society, their cities wasn’t short of heaven on earth at their time. They had baked brick houses with drainage systems and even water supply, what else on earth you could ask five millenniums ago.
1. The Collapse Of Indus Valley Civilization Is Still A Mystery
Indus valley civilization was doing great in overall human development for hundreds of years, but around 1800 BCE signs of gradual decline began to occur. Probably 100 years later around 1700 BCE most people just abandoned the cities.
Although the exact cause of decline is not known but there are several theories to explain what could’ve happened. Some suggest that the peaceful nature of Indus Valley people and avoiding the development of weapons was a lousy military strategy, and people of an Indo-European tribe from central Asia called “Aryans” invaded the land.
Many historians also believe that the collapse of Indus valley civilization may have caused by a large scale drought and probably the decline in trade with Egypt and Mesopotamia.
Some believe that a massive earthquake completely changed the course of the river, hence lead to the lack of water for irrigation and thus migration. But deforestation, tuberculosis or floods could have also contributed to the decline.
However, people of Indus valley civilization didn’t disappear suddenly, many elements of this civilization can be found in later cultures that emerged centuries after their collapse. Recent archaeological excavations indicate that the decline of Indus valley civilization drove people more towards the east. After 1900 BCE the number of sites significantly increased in India. Probably their descendants are living peacefully in India and Pakistan mixed with dozens of other races.
