TExES Social Studies 7-12 (232)

Because this guide does not use calendar years, every chapter teaches chronology through centuries, eras and sequence. Build a mental timeline of each region and then connect the regions to one another through trade, migration, conquest and the spread of ideas. Several topics that appear in world history courses are tested in other domains: the beliefs of the world religions and the art movements (Chapter 4.2), law codes, political philosophers and forms of government (Chapter 5.3), economic theorists and systems (Chapter 6.1) and the diffusion of science and technology, including named scientists (Chapter 6.3). This section mentions them where they belong in the story and points you to those chapters for the tested details.

This chapter serves Competency 001. It covers the geography, agriculture and cultural diffusion that shaped early and classical civilizations, and the location, political organization and contributions of civilizations in Africa (Egypt, Kush, Aksum and sub-Saharan Africa), the Mediterranean (Phoenicia, Greece and Rome), Mesoamerica (Olmec and Maya), the Andes (Chavín and other early Andean societies), Southwest Asia (Sumer, Babylon, Assyria, Persia and the Israelites) and Asia (the Indus Valley, the Shang, Zhou, Qin and Han dynasties of China, the Maurya and Gupta empires of India, and early Japan).

The shift from foraging to farming, often called the Neolithic Revolution, began in several places independently: the Fertile Crescent of Southwest Asia (wheat, barley, sheep and goats), the Yellow River valley of China (millet) and the Yangtze valley (rice), Mesoamerica (maize, beans and squash), the Andes (potatoes and quinoa) and parts of Africa (sorghum and yams). Farming produced food surpluses. Surpluses allowed larger, permanent populations, and some people could then work at tasks other than food production. That specialization of labor is the first step toward a civilization.

Historians usually define a civilization by a cluster of traits: cities, an organized government, a complex religion with priests and temples, job specialization, social classes, a writing or record-keeping system, and monumental public works. The early civilizations of Mesopotamia, Egypt, the Indus Valley and China all grew along rivers. The rivers supplied fertile silt, transportation and water, but they also flooded, so communities had to cooperate on dikes and canals. That need for cooperation encouraged strong central authority. Chapter 4.3 covers the Neolithic Revolution and human-environment interaction in more detail.

Geography also explains differences among civilizations. Egypt's Nile flooded on a predictable yearly schedule, and deserts on both sides protected the valley from invasion; Egyptian culture was stable and optimistic. Mesopotamia's Tigris and Euphrates flooded unpredictably, and the open plain invited invaders, so its rival city-states were conquered again and again. Greece's mountains and islands divided the land into small valleys, which encouraged independent city-states and seafaring.

Cultural diffusion is the spread of ideas, goods and practices from one society to another. It occurs through trade (the Phoenicians carried their alphabet across the Mediterranean), conquest (Alexander the Great spread Greek culture across Southwest Asia), migration (Bantu-speaking peoples spread ironworking and their languages across central and southern Africa) and religious missions (Buddhism moved from India along trade routes to China, Korea and Japan).

Exam Tip: When a question asks why a civilization developed a certain way, look first for a geographic answer: a river's flood pattern, natural barriers, access to the sea, or the location of a trade route. TExES items often reward the option that ties a political or cultural trait to the physical setting.

Sumer, in southern Mesopotamia (modern southern Iraq), produced the earliest known cities, such as Uruk and Ur, around 3500 B.C.E. Each Sumerian city-state had its own ruler and patron god, honored at a stepped temple tower called a ziggurat. The Sumerians developed cuneiform, wedge-shaped writing pressed into clay tablets, at first to keep temple and trade records. Rival city-states fought over water and land, which left them open to conquest.

Sargon of Akkad united the Sumerian cities into what is often called the first empire. Later, Babylon rose under Hammurabi, whose written law code is one of the oldest surviving legal collections (its principles are covered in Chapter 5.3). The Assyrians, from northern Mesopotamia, built a large empire through a powerful army that used iron weapons, siege engines and terror, including mass deportations of conquered peoples. After Assyria fell, a revived Babylonian state under Nebuchadnezzar conquered Jerusalem and deported many of its people.

The Persian Empire, founded by Cyrus the Great in the sixth century B.C.E., became the largest empire the world had yet seen, stretching from Egypt and Anatolia to the Indus River. The Persians are remembered for administrative skill rather than terror. Darius I divided the empire into provinces called satrapies, each governed by a satrap and watched by royal inspectors known as the "eyes and ears of the king." He built the Royal Road, more than 1,500 miles long, with relay stations for messengers, and he standardized coins and taxes. Cyrus allowed deported peoples, including the Jews in Babylon, to return home and rebuild their temples. Tolerance of local customs and religions kept a huge, diverse empire relatively stable.

The Israelites were a small people of the eastern Mediterranean coast whose main contribution was religious: ethical monotheism, the belief in one God who demands moral behavior. Their history and laws are recorded in the Hebrew Bible. Chapter 4.2 covers Judaism's beliefs.

Major civilizations of ancient Southwest Asia

Common Trap: Do not confuse Assyrian and Persian rule. Both built large empires, but Assyria held its lands mainly through fear and deportation, while Persia relied on provincial administration, roads and tolerance. An option that describes freeing captive peoples to return home describes Persia under Cyrus.

Egypt was united around 3100 B.C.E. when a ruler traditionally called Menes joined Upper Egypt (the south, upstream) and Lower Egypt (the delta in the north). The pharaoh was considered a god-king, and a large bureaucracy of scribes collected taxes in grain. Egyptians wrote in hieroglyphics on stone and papyrus, built massive tombs and temples, developed a 365-day calendar tied to the Nile flood, and practiced mummification based on their beliefs about the afterlife.

Kush lay south of Egypt along the upper Nile in Nubia (modern Sudan). For centuries Egypt controlled Nubia and traded with it for gold, ivory, ebony and enslaved people, and Kush absorbed many Egyptian customs, including pyramid building and the worship of Egyptian gods. In the eighth century B.C.E. the roles reversed: Kushite kings such as Piye conquered Egypt and ruled it as pharaohs of Egypt's Twenty-fifth Dynasty. After Assyrian armies drove them out, the Kushites moved their capital south to Meroë. Meroë became a major center of iron smelting, surrounded by slag heaps, and a trading hub linking the Nile with the Red Sea and inner Africa.

Aksum, in the highlands of modern Ethiopia and Eritrea, rose in the first centuries C.E. and eventually conquered Meroë. Aksum controlled trade between the Roman world, Arabia and India through its Red Sea port of Adulis, exporting ivory and gold. It minted its own coins, built tall carved stone pillars called stelae, and developed the Ge'ez script. In the fourth century C.E. King Ezana converted to Christianity, making Aksum one of the earliest Christian states, and Ethiopia has kept an Orthodox Christian tradition ever since.

Elsewhere in sub-Saharan Africa, the Nok culture of present-day Nigeria worked iron and made distinctive terracotta sculptures. Over many centuries Bantu-speaking peoples migrated from West-Central Africa east and south, which explains why hundreds of related Bantu languages are spoken across much of the southern half of the continent today.

Memory Aid: Follow the Nile and then the Red Sea: Egypt (north) ruled Kush; Kush (south) ruled Egypt, then made iron at Meroë; Aksum (farther southeast, on the Red Sea) conquered Meroë, minted coins and became Christian.

The Phoenicians lived in city-states such as Tyre, Sidon and Byblos along the coast of modern Lebanon. With little farmland, they turned to the sea, becoming the leading sailors and merchants of the Mediterranean. They traded cedar timber, glass and a costly purple dye made from sea snails, and they founded colonies across North Africa and the western Mediterranean. The greatest, Carthage, later fought Rome in the Punic Wars. Their most lasting contribution was a phonetic alphabet of about 22 symbols for consonant sounds, far simpler than cuneiform or hieroglyphics. The Greeks adapted it and added vowels, and the Romans adapted the Greek version into the Latin alphabet used for English.

Greek civilization followed the earlier Minoan (on Crete) and Mycenaean (on the mainland) cultures. Mountains and islands divided Greece into small valleys and pushed Greeks to the sea, which produced the polis, or independent city-state, each with its own government. Athens developed direct democracy for adult male citizens, while Sparta was a military oligarchy that trained all male citizens as soldiers. The Peloponnesian War between Athens and Sparta weakened the city-states, and Philip II of Macedonia conquered them. His son Alexander the Great conquered the Persian Empire, Egypt and lands to the Indus River. Alexander's conquests began the Hellenistic era, a blend of Greek, Persian, Egyptian and Indian culture centered on new cities such as Alexandria in Egypt. Greek philosophers and the Athenian model of democracy are treated in Chapters 5.3 and 6.3.

Rome began as a small kingdom in central Italy and became a republic after its people expelled their last king. The republic had two consuls elected each year, a Senate dominated by aristocratic patricians, and assemblies through which the common plebeians gained rights over time, including the Twelve Tables, Rome's first written laws. Rome conquered Italy, defeated Carthage in three Punic Wars (Hannibal famously crossed the Alps with elephants in the second), and took over the Hellenistic East. Julius Caesar became dictator and was assassinated; his heir Octavian, renamed Augustus, became the first emperor. The Pax Romana, about two centuries of relative peace, followed. Romans spread Latin, built roads, aqueducts, arches and concrete structures, and developed legal principles that later shaped European law.

The western empire declined from internal and external causes: political instability, heavy taxation, inflation and debased coinage, dependence on hired soldiers, a split into eastern and western halves, and invasions by Germanic peoples pushed west by the Huns. The western empire ended in the late fifth century C.E. The eastern half, centered on Constantinople, survived as the Byzantine Empire (Chapter 1.2).

The Greek world compared with the Roman world

The Indus Valley (Harappan) civilization flourished in modern Pakistan and northwest India. Cities such as Harappa and Mohenjo-daro were laid out on grid plans with standardized fired bricks, drainage systems, public baths and granaries. Their script has never been deciphered. The civilization declined, possibly because of shifting rivers, climate change or flooding. Indo-European-speaking Aryans later entered the region; their Vedic literature and social divisions (varna) became foundations of later Hindu society (Chapter 4.2 covers Hinduism and Buddhism).

The Maurya Empire, founded by Chandragupta Maurya in the late fourth century B.C.E., united most of the subcontinent for the first time. It had a large army, a bureaucracy and a spy network. His grandson Ashoka conquered Kalinga in a bloody war and was so troubled by the slaughter that he converted to Buddhism. He then ruled by dharma (moral law), carved edicts on rocks and pillars urging nonviolence and tolerance, built roads with rest houses, and sent Buddhist missionaries abroad, helping Buddhism spread to Sri Lanka and beyond. The empire broke apart after his death.

The Gupta Empire, centered on the Ganges valley in the fourth through sixth centuries C.E., is called India's golden age. It was smaller and less centralized than the Maurya Empire, letting local rulers keep power in return for loyalty. Hinduism revived under Gupta patronage, Sanskrit literature flourished (the poet Kalidasa), and scholars made major advances in mathematics and medicine, including the decimal system and the concept of zero (Chapter 6.3).

Common Trap: Maurya is the large, centralized empire associated with Ashoka and the spread of Buddhism; Gupta is the later, more decentralized golden age associated with a Hindu revival and classical science and literature. A question about edicts carved on pillars points to Maurya.

China's early civilization grew along the Huang He (Yellow River), whose yellow loess soil was fertile but whose floods were so destructive that it was called "China's Sorrow." The Shang dynasty is the first with written records. Shang kings ruled with aristocratic warriors, cast elaborate bronze vessels, and used oracle bones (inscribed animal bones and shells) to ask questions of ancestors; the inscriptions are the earliest Chinese writing, and the script's characters are the ancestors of modern Chinese characters.

The Zhou overthrew the Shang and justified the change with the Mandate of Heaven: heaven grants the right to rule to a just ruler and withdraws it from a corrupt one, shown by disasters and rebellion. This idea produced the dynastic cycle, in which dynasties rise, decline and are replaced. The Zhou governed through a decentralized system in which lords held land in return for loyalty. As royal power weakened, the Warring States period followed, and in that chaotic era thinkers produced Confucianism, Daoism and Legalism (Chapter 4.2 and Chapter 5.3).

The Qin state conquered its rivals and unified China in the late third century B.C.E. Its ruler took the title Shi Huangdi, "first emperor." Guided by Legalism, he abolished the old feudal states and divided China into commanderies run by appointed officials, standardized writing, coins, weights and measures and even axle widths, built roads and canals, and linked earlier walls into an early Great Wall using forced labor. The harsh dynasty collapsed soon after his death.

The Han dynasty followed and lasted about four centuries, a period so formative that many Chinese still call themselves "people of the Han." The Han kept the Qin's centralized structure but softened it with Confucian values. Emperor Wudi made Confucianism the official philosophy and began choosing officials partly through knowledge of Confucian texts, an early form of the civil service examination. Han armies expanded into Central Asia, Korea and Vietnam, and the envoy Zhang Qian's missions west helped open the Silk Road, which carried Chinese silk to Rome.

Early Chinese dynasties at a glance

Memory Aid: "Some Zebras Quietly Hum" gives the order Shang, Zhou, Qin, Han. Remember that the shortest dynasty, the Qin, did the most to unify China, and that the Han kept the Qin structure while replacing harsh Legalism with Confucian ideals.

Japan's island geography separated it from the mainland enough to protect it from invasion but allowed selective borrowing. Early Japanese society was organized into clans, each with its own chief and protective spirit, and the native Shinto tradition honored kami, spirits in nature and ancestors. The Yamato clan became dominant and claimed descent from the sun goddess, the origin of the imperial line. Beginning around the sixth and seventh centuries C.E., Japan borrowed heavily from China, often by way of Korea: Buddhism, Chinese characters, Confucian ideas and a Chinese-style government. Japan adapted rather than copied: the emperor remained a sacred figure, and real power stayed with aristocratic families.

The Olmec, who lived along the hot, wet Gulf Coast of southern Mexico, are often called the "mother culture" of Mesoamerica. They built ceremonial centers such as San Lorenzo and La Venta, carved colossal stone heads of basalt, played a ritual ball game and worshiped a jaguar-related deity. Through trade in jade and obsidian their art style and religious ideas spread widely, and later peoples inherited Olmec elements such as the ball game, pyramid-temples and calendar systems.

The Maya built a civilization of independent city-states, such as Tikal, Copán and Palenque, in the rain forests of the Yucatán Peninsula, Guatemala and Belize. Each city was ruled by a king who was also a religious figure, and cities fought frequent wars and formed shifting alliances; the Maya never formed one unified empire. They built stepped pyramid-temples and palaces, created the most complete writing system in the ancient Americas (hieroglyphs recorded on stone monuments and bark-paper books called codices), developed an accurate calendar and used a number system that included zero.

In the Andes, the Chavín culture, centered on a temple complex at Chavín de Huántar in the highlands of Peru, spread a shared religious art style featuring jaguars, snakes and eagles across a wide area. Like the Olmec, Chavín influence came mainly through religion and trade rather than conquest. No Andean society developed a writing system; the later Inca kept records with knotted cords called quipu.

Early civilizations of the Americas

Exam Tip: Both the Olmec and Chavín are tested as early "mother" or foundational cultures that spread influence through shared religion and art rather than through empire building. The Maya are tested for city-states, writing and calendar science; empire building and road systems belong to the later Aztec and Inca (Chapter 1.2).

The classical era (roughly 500 B.C.E. to 500 C.E.) saw large empires at both ends of Eurasia: Persia, Rome, Maurya and Gupta India, and Qin and Han China. They shared common challenges: governing large and diverse populations, defending long borders, collecting taxes and keeping communications open. Their solutions included road networks (the Persian Royal Road, Roman roads, Qin and Han roads), standardized coinage and measures, bureaucracies, official languages or scripts, and a unifying ideology (the Mandate of Heaven, Roman citizenship, Ashoka's dharma). The Han and Roman empires were linked indirectly by the Silk Road and both declined in similar ways: overexpansion, heavy taxes, weak central governments and pressure from nomadic invaders.

Early civilizations grew in river valleys where farming surpluses supported cities, specialization, government and writing; geography shaped each civilization's politics and outlook.

Southwest Asia produced Sumerian city-states and cuneiform, Babylonian law, Assyrian military empire, Persian administration and tolerance, and Israelite ethical monotheism.

Kush absorbed Egyptian culture, ruled Egypt for a time, and became an iron-working center at Meroë; Aksum controlled Red Sea trade and became an early Christian kingdom.

Phoenicians spread the alphabet by sea; Greek geography produced city-states; Rome moved from republic to empire and spread roads, law and Latin.

Maurya India (Ashoka) and Qin China (Shi Huangdi) unified their regions; the Gupta and Han ruled golden ages that shaped later culture.

The Olmec and Chavín spread influence through religion and art; the Maya built rival city-states with writing and calendars.
