Harappa is located in the Indus Valley

Its advanced culture and food surpluses made it one of the largest of its time

It was occupied between 3000-1500 BCE

The Harappan culture was so advanced that some of their seals have features seen in modern Hinduism, such as the god Shiva

The Harappan influence spread across a 500,000-square-mile area (This was greater than Egypt or Mesopotamia)

Archaeologists can’t figure out the Harappan writing system. It seems to be based on pictograms, almost like Sumerian cuneiform

Harappan houses were built with burnt bricks to last thousands of years. The interlocking brick pattern increased how strong the walls were

Many houses were around two or one stories tall, some with courtyards

They had functioning draining systems that would lead into the wells inside the homes. Many houses even had separate bathing areas

Harappans were long-distance traders, they used boats and what seems to be the first wheeled vehicles

Their trading route was so far that they extended over the valley's mountains into what is now known as Afghanistan, Iran, and Iraq

 Archaeologists have found Harappan copper, gold, and ivory in these parts
