Nomads are people who constantly move in search of food and water, characterized by small populations, equality, and no private property. Pastoralists herd animals and are mobile but live in clans, spreading culture through migration and trade.

The Neolithic Revolution, or the beginning of farming, led to stable villages, population growth due to surplus food, job specialization, the emergence of social classes, and the formation of governments to manage resources and rules.

Civilizations are characterized by cities, central governments, complex religions, social class ranking, writing systems, specialized jobs, and public works. Religion and government were often linked, with rulers claiming divine backing.

Primary sources are created at the time of an event (e.g., diaries, artifacts), while secondary sources are created after the event (e.g., textbooks, history articles).

Bias refers to a one-sided perspective, whereas objectivity is neutral and evidence-based. Credible sources are reliable and supported by evidence, often confirmed by multiple sources.

HIPP analysis involves examining Historical Context (what was happening), Intended Audience (who it's for), Purpose (why it was written), and Point of View (author's bias and motives).

The Code of Hammurabi was the first written law code, featuring unequal laws based on class and gender. Its purpose was to show divine authority, maintain order through fear, and protect property, influencing future law systems.

Greece's mountainous terrain led to the development of separate city-states (poleis). Its islands and coastline made maritime trade important, and limited farmland encouraged the establishment of colonies abroad.

Ancient Greece saw various forms of government, including Monarchy (king), Aristocracy (nobles), Oligarchy (small elite group), and Direct Democracy (citizens vote directly), as seen in Athens.

Athenian citizenship was restricted to free, native-born males, excluding women, slaves, and foreigners, which limited the scope of its democracy.

Athens focused on philosophy, arts, and the navy, with a trade-based economy and limited rights for women. Sparta prioritized military oligarchy, discipline, and agriculture, with women having more rights and physical training.

Athens laid the foundations for Western democracy and philosophy, while Sparta was admired for its discipline but had a limited cultural legacy.

The Greek victory in the Persian Wars led to Athens becoming powerful and forming the Delian League, an alliance that created an Athenian empire and generated wealth.

The Golden Age of Pericles saw advancements in art, drama, and philosophy, with an expansion of democracy. However, the Peloponnesian War resulted in a Spartan victory, weakening Greece and making it vulnerable.

Rivalry and constant warfare between Greek city-states weakened them, making them an easy target for conquest by Macedonia under Alexander the Great.

The Roman Republic featured Patricians (elite), Plebeians (common people), a powerful Senate, two Consuls with limited terms, and Tribunes to protect plebeian rights. The Twelve Tables provided a written law code.

Rome implemented a system of checks and balances, including limited terms for leaders and the role of Tribunes, to prevent any single individual from accumulating too much power.

Rome's victories in the Punic Wars against Carthage gave it control of the Mediterranean. However, this expansion led to increased wealth inequality, expanded slavery, and fewer opportunities for the poor.

The growing wealth gap, revolts by the poor, soldiers' loyalty shifting to generals, and the rise of Julius Caesar as a dictator contributed to the end of the Republic and the subsequent civil wars.

The Pax Romana was a 200-year period of peace, trade, and engineering achievements in Rome, including roads, aqueducts, the spread of Roman law, widespread citizenship, and economic stability.

The fall of Rome in 476 CE was caused by political corruption, unstable emperors, economic issues like inflation and heavy taxation, social decline in civic duty, a weak military relying on mercenaries, and external Germanic invasions.

In Classical China, the Mandate of Heaven dictated that rulers were chosen by the gods, and if they ruled poorly, the gods would withdraw support, leading to natural disasters and rebellion, signaling the fall of a dynasty.

The Qin Dynasty, under Shi Huangdi, implemented Legalism for strict control, unified weights and writing systems, built the Great Wall for defense, and banned Confucian philosophy, burning books. Though short-lived, it laid foundations for China.

The Han Dynasty, considered a Golden Age, promoted Confucianism, established Civil Service Exams for merit-based government, expanded trade via the Silk Road leading to cultural diffusion and wealth, and encouraged assimilation. Achievements include paper, the wheelbarrow, and silk production.
