Ancient and World History

They were called "Magna Grecia", or "Great Greece".

Qin Shi Huang (259-210 BCE) was the first emperor of the Qin Dynasty and the first emperor of a unified China. He is credited with unifying China in 221 BCE and beginning the construction of the Great Wall. The correct spelling is 'Qin Shi Huang' - the option B has a typo spelling it as 'Quin Shi Huangdi'.

The First Buddhist Council was held at Rajagriha (modern-day Rajgir) shortly after Buddha's death around 400 BCE. It was convened to preserve Buddha's teachings and settle disciplinary matters.

Zero as a complete number with arithmetic properties was developed by Indian mathematicians. Brahmagupta formalized zero's use in the 7th century CE, explaining operations like addition and subtraction with zero. While Babylonians used a placeholder symbol, Indians were the first to treat zero as a number in its own right.

During the pre-Gupta period (roughly 200 BCE - 300 CE), the Roman Empire had the most extensive maritime trade with India, particularly through the Red Sea ports. The discovery of Roman coin hoards and the Periplus of the Erythraean Sea document this robust trade relationship. While trade existed with Southeast Asia, Central Asia, and China, Roman trade was unmatched in volume and value.

Diodorus Siculus, Ctesias of Cnidos, and Nearchus were contemporaries of Alexander the Great who wrote firsthand accounts of his campaigns. Plutarch, however, wrote 'Lives of the Noble Greeks and Romans' nearly 150 years after Alexander's death (c. 46-120 CE). His biography of Alexander is derived from earlier sources, making him the odd one out among these ancient writers.

The Battle of the Hydaspes was fought on the banks of the Jhelum River (called 'Jehium' here, likely a typo for Jhelum/Jehlum) between Alexander and King Porus.

The Qing Dynasty (also called the Manchu Dynasty) was China's last feudal imperial dynasty, ruling from 1644 until 1912 when the Republic of China was established. The Manchus were an ethnic group from northeast China who conquered China and established the Qing.

The ancient Persians were the first to refer to the river Sindhu as 'Hindu' because their language did not have the 's' sound, so they replaced it with 'h'. This term later evolved into 'Hindu' and 'India'.

The Indus Valley Civilization (Harappan civilization) is renowned for its advanced urban planning with grid-based street layouts, sophisticated drainage systems, and standardized baked brick construction. Vedic civilization was primarily rural with no major cities.

King Nebuchadnezzar II (605-562 BCE) of the Neo-Babylonian Empire built the Hanging Gardens for his wife Amytis of Media, who missed the green hills of her homeland. The Gardens were one of the Seven Wonders of the Ancient World. Augustus was a Roman emperor, Demetrius was a Greek general, and Ptolemy Philadelphus I ruled Egypt.

The potter's wheel was invented in Mesopotamia around 3500 BCE during the Ubaid period, revolutionizing pottery production. This invention allowed for faster, more uniform pottery production. While other civilizations later developed pottery techniques, Mesopotamia was the first to use the wheel. China and Egypt developed significant pottery traditions later, and India's pottery came even later.

James Prinsep, a British scholar and antiquarian, deciphered the Brahmi script in 1837 by studying the inscriptions at Sarnath and comparing them with later Indo-Greek coin legends. His breakthrough allowed historians to read Ashoka's edicts and understand ancient Indian history. William Jones founded the Asiatic Society, R. Samasastri was an epigraphist, and Mortimer Wheeler was an archaeologist.

The Sumerians, who settled in southern Mesopotamia (modern-day Iraq), established the world's first known cities around 4000-3500 BCE, including Uruk and Ur, with advanced systems of writing (cuneiform), mathematics, and governance that define urban civilization. While Egyptians and Chinese also developed early civilizations, the Sumerian city-states predate them. "Mesopotamians" is a broader regional term that includes Sumerians but also later cultures like Babylonians and Assyrians.
