Developments and Processes

Overview

AP World History: Modern Developments and Processes is the first historical thinking skill in the course. It asks you to identify and explain historical developments and processes, which means naming what happened and then explaining how and why it unfolded over time. This skill is the foundation for everything else you do on the exam, from multiple-choice questions to written responses.

In short: you spot a historical change, trend, or event, and you explain it accurately using specific evidence. Skill 1 shows up on both the multiple-choice section and the free-response questions, so getting comfortable with it early pays off across all nine units.

What Developments and Processes Means

A historical development is a specific event, idea, institution, technology, or trend that emerged in the past. A historical process is how that development unfolded, spread, or changed over time.

Examples of the difference:

• Development: The Song Dynasty used a Confucian imperial bureaucracy.
• Process: How that bureaucracy expanded commercial growth across centuries.
• Development: The caravel was a new ship design.
• Process: How improved ship design made transoceanic travel and trade possible.

You are not just memorizing facts. You are showing that you understand what a historical change was and how it actually worked.

What This Skill Requires

This skill breaks into two moves: identifying and explaining.

• Identify means naming the concept, development, or process correctly. This is the first step and the lower-difficulty task.
• Explain means going further to describe how or why something happened, including causes, effects, or change over time.

The jump from identifying to explaining is where points are won or lost. A response that only names something is incomplete. A response that explains the relationship, mechanism, or significance earns more.

Subskills You Need

The CED lists two subskills under Skill 1. Both apply to multiple-choice and free-response questions.

1.A: Identify a historical concept, development, or process

You recognize and name an accurate historical development. This often looks like:

• Picking the answer choice that correctly identifies what a source describes
• Naming a relevant development in a short-answer or essay response

Example: Identifying that Portugal developed maritime technology and navigational skills during the 1450 to 1750 period.

1.B: Explain a historical concept, development, or process

You go beyond naming and explain how or why a development happened, or how it changed over time. This often looks like:

• Choosing the answer that correctly explains a cause, effect, or reason
• Writing a sentence or two in an FRQ that explains the mechanism behind an event

Example: Explaining that bringing Constantinople under Islamic rule was central to Ottoman rulers' claims to political legitimacy, which is why the architect Sinan aimed to surpass the Hagia Sophia's dome.

How It Shows Up on the AP Exam

Skill 1 appears across the entire exam.

Multiple-choice section: Many questions ask you to identify or explain a development tied to a stimulus. You read a source, map, or chart, then choose the option that correctly names or explains the relevant historical process.

Short-answer questions (SAQs): These often ask you to identify one development and then explain it. The verbs in the prompt matter. "Identify" wants a name. "Explain" wants reasoning.

Document-based question and long essay: Skill 1 supports your evidence. You cannot build a strong argument without correctly identifying and explaining the developments you use as support.

Practical tip: read the verb in any prompt first. If it says "explain," a one-word identification will not earn the point.

Examples Across the Course

Skill 1 applies to every unit. Here are varied examples drawn from across the course timeline.

Notice the pattern. The left column is a name. The right column adds a how or why.

How to Practice Developments and Processes

Build the habit of separating the two moves.

• Turn facts into explanations. Take any term from your notes and write one sentence naming it, then one sentence explaining how or why it mattered.
• Watch the verbs. When you review MCQ stems, underline whether they ask you to identify or explain. Match your thinking to the verb.
• Use cause and effect language. Words like "because," "led to," "resulted in," and "as a result" signal that you are explaining, not just listing.
• Practice with sources. Read a document or map, then say out loud what development it shows and what process caused or resulted from it.
• Drill across periods. Pull one development from each unit and write a quick identify-then-explain pair. This keeps you ready for any prompt.

Common Mistakes

• Stopping at identification. Naming a development is only half the skill. If the prompt says explain, add the how or why.
• Listing without connecting. A pile of facts is not an explanation. Connect the development to a cause, effect, or change.
• Being vague. "Things changed" is not an explanation. Name the specific mechanism, like trade technology, religious legitimacy, or political fragmentation.
• Ignoring the time element. A process unfolds over time. Show change or continuity when the prompt calls for it.
• Misreading the prompt verb. "Identify," "describe," and "explain" ask for different amounts of detail. Match your answer to the task.

Quick Review

• Skill 1 has two subskills: 1.A (identify) and 1.B (explain).
• A development is what happened. A process is how it unfolded over time.
• Identify means name it accurately. Explain means add the how or why.
• Both subskills apply to multiple-choice and free-response questions.
• Read the verb first, then match your answer depth to it.
• The skill applies to all nine units, so practice identify-then-explain pairs across the whole timeline.
