Primary source

A document, artifact, recording, or image created by someone who participated in or directly witnessed an event, such as a diary, letter, photograph, or law. It offers firsthand evidence rather than later interpretation.

Related: Secondary source, Historical thinking
Secondary source

An account, analysis, or textbook written after an event by someone who did not witness it firsthand. It interprets and synthesizes primary evidence, often reflecting a particular historian's argument or perspective.

Related: Primary source, Historiography
Historical thinking

The set of reasoning skills historians use: sourcing documents, contextualizing events, corroborating evidence across sources, and close reading. It emphasizes evaluating perspective and reliability rather than memorizing isolated facts.

Related: Primary source, Point of view
Point of view

The position, background, or interests from which a source's author speaks, shaping what they notice and how they describe it. Identifying it helps readers judge bias, purpose, and the limits of a document's testimony.

Related: Bias, Historical thinking
Bias

A systematic slant or preference in how information is selected, framed, or presented. In sources, bias may be intentional or unconscious and does not automatically make evidence useless; it must be identified and accounted for.

Related: Point of view, Corroboration
Corroboration

The practice of comparing multiple sources to see whether they agree on key details. Agreement strengthens confidence in a claim; disagreement prompts further investigation into why accounts differ.

Related: Historical thinking, Bias
Chronology

The arrangement of events in the order they occurred, often shown on timelines. Establishing sequence helps explain cause and effect and prevents anachronistic errors, such as placing an event before its necessary preconditions.

Related: Cause and effect, Periodization
Periodization

The practice of dividing the past into named eras, such as the Colonial or Reconstruction periods. Boundaries are interpretive choices, and different historians may draw them differently depending on the theme they study.

Related: Chronology, Historiography
Cause and effect

The relationship in which one event, condition, or decision contributes to a later outcome. Historians distinguish short-term triggers from long-term underlying conditions and recognize that multiple causes usually operate together.

Related: Chronology, Contingency
Contingency

The idea that historical outcomes were not inevitable but depended on specific choices, accidents, and circumstances. It encourages explaining why events happened rather than assuming they had to happen as they did.

Related: Cause and effect, Historical thinking
Historiography

The study of how history has been written and interpreted over time, including changing methods and schools of thought. It examines why accounts of the same event differ across generations of scholars.

Related: Secondary source, Periodization
Geography's five themes

Related: Region, Human-environment interaction
Region

An area defined by shared characteristics, such as climate, language, economy, or political boundaries. Regions can be formal, functional, or perceptual, and their borders may be fuzzy or contested.

Related: Geography's five themes, Human-environment interaction
Human-environment interaction

The reciprocal relationship in which people adapt to, modify, and depend on their physical surroundings. Examples include irrigation, urbanization, and responses to natural hazards, each with environmental consequences.

Related: Region, Geography's five themes
Economics: scarcity

The condition in which human wants exceed the limited resources available to satisfy them. Scarcity forces individuals and societies to make choices, which creates opportunity costs and drives the need for allocation decisions.

Related: Opportunity cost, Supply and demand
Opportunity cost

Related: Economics: scarcity, Supply and demand

Related: Opportunity cost, Market economy
Market economy

An economic system in which private individuals and firms make most production and consumption decisions through prices rather than government command. Competition and self-interest are assumed to guide resource allocation.

Related: Supply and demand, Command economy
Command economy

An economic system in which central authorities decide what is produced, how, and for whom. Government planning replaces market prices as the main coordinating mechanism, which can reduce choice and weaken price signals.
