why is mohenjo daro considered one of the most advanced cities of its time
Mohenjo-daro Mohenjo-daro was built in the 26th century BCE.[10] It was one of the largest cities of the ancient Indus Valley Civilization, also known as the Harappan Civilization,[11] which developed around 3,000 BCE from the prehistoric Indus culture. At its height, the Indus Civilization spanned much of what is now Pakistan and North India, extending westwards to the Iranian border, south to Gujarat in India and northwards to an outpost in Bactria, with major urban centers at Harappa, Mohenjo-daro, Lothal, Kalibangan, Dholavira and Rakhigarhi. Mohenjo-daro was the most advanced city of its time, with remarkably sophisticated civil engineering and urban planning.[12] When the Indus civilization went into sudden decline around 1900 BCE, Mohenjo-daro was abandoned.[10][13]
Athens Classical Athens was a powerful city-state that emerged in conjunction with the seagoing development of the port of Piraeus, which had been a distinct city prior to its 5th century BC incorporation with Athens. A centre for the arts, learning and philosophy, home of Plato's Academy and Aristotle's Lyceum,[6][7] it is widely referred to as the cradle of Western civilization and the birthplace of democracy,[8][9] largely because of its cultural and political impact on the European continent, and in particular the Romans.[10] In modern times, Athens is a large cosmopolitan metropolis and central to economic, financial, industrial, maritime, political and cultural life in Greece. In 2012, Athens was ranked the world's 39th richest city by purchasing power[11] and the 67th most expensive[12] in a UBS study.
