HIST 202: Principles of War

A study guide to UMGC's HIST 202, a study of the nine classic principles of war and how they shaped military policy and planning.

Updated October 2026 · 5 min read

HIST 202 at the University of Maryland Global Campus is a three-credit study of the nine classic principles that guide the conduct of war at the strategic, operational and tactical levels. UMGC describes them as the foundation of the art and science of the military profession.

The stated aim is to use primary and secondary historical resources to explore how past theory and practice have shaped the underlying policy, strategic planning and operational procedures of today's military and national security agencies. The difficulty is applying abstract principles to messy historical campaigns without forcing the evidence to fit.

What HIST 202 Covers

The catalog names the nine principles without listing them, and your instructor will use a specific list from your course materials. The table groups the course themes.

ThemeWhat you work on
The nine principlesThe classic principles guiding war, as defined in your course readings
Levels of warStrategic, operational and tactical, and how a decision at one level affects the others
Theory and practiceHow writers on war and actual campaigns relate to one another
Policy and planningHow past experience shaped the planning of modern military and national security agencies
Historical resourcesUsing primary and secondary sources to study campaigns

Key Concepts Explained

Principles as Tools, Not Laws

A principle is a guide for judgment. A strong answer shows how commanders applied, bent or ignored a principle and what resulted. Avoid saying a battle was won "because" of one principle without weighing other factors such as supply, weather and politics.

Invented illustration: If your list includes a principle about concentrating forces, ask whether a commander concentrated at the right place, what he gave up elsewhere, and whether the enemy's response mattered more.

Three Levels of War

Strategic decisions concern war aims and national resources; operational decisions link campaigns; tactical decisions concern engagements. A mistake at the strategic level can undo tactical success.

Illustration: A tactically successful battle may be strategically pointless if it does not serve the war aims. Separate the levels in your analysis.

Using Primary Sources About War

Orders, dispatches and memoirs show intent but also self-justification. Say who wrote the source and when, and compare it with other accounts.

Typical Assignments and How to Approach Them

The catalog does not list assessments, so these are typical for the aim. Confirm in your syllabus.

Assignment typeWhat it testsHow to approach it
Discussion postsUnderstanding of principlesDefine a principle in your own words and test it on one example
Case-study analysisApplying theory to a campaignPick a campaign, apply each relevant principle and judge how well it fits
Source analysisEvaluating evidenceIdentify author, purpose and audience, then compare with another account
Research paperArgument across levelsFrame a question that spans strategy and tactics and support it with sources

Structuring a Case Study

Case-study papers are easier when each principle gets the same treatment. The table is a planning aid.

PartWhat to include
ContextDate, opponents, war aims and constraints
Principle by principleHow the principle appeared in decisions, with evidence
Level of warWas the effect strategic, operational or tactical?
JudgmentDid following or breaking the principle help or hurt?

Use only the principles that help your argument. Forcing all nine into a short paper produces list-like writing.

Linking Past to Present

The catalog says past theory and practice shaped today's policy, strategic planning and operational procedures. To show that link, trace one idea, such as the importance of clear objectives, from a historical campaign to a modern planning concept in your readings.

State the connection carefully: influence needs evidence, such as a doctrine document citing the older writer.
