How the world wars shaped the world we live in

See how the two world wars made the world you live in.

Trace a specific legacy through dated decisions and institutions, then distinguish the original purpose from later results. The world wars changed many arrangements, but a present-day border or conflict can also have earlier roots and later causes. One date cannot explain the whole present.

Start with three things you can do today

A starting goal

I want to understand how the two world wars shaped the world I live in: borders, institutions, alliances and ideas. Help me see the connections without a memorized timeline.

Change any word so it fits your situation. The course is built from what you type and a few setup questions.

Start today

Three things you can do before the course exists.

Useful on their own. The course is for when you want the whole skill, not just the first move.

  1. Follow a documented institutional link

    The UN's history records the drafting and signing of its Charter in San Francisco in 1945 and the organization's official beginning on 24 October 1945 after ratification. Its stated purpose included preventing another world war. This gives a specific connection between wartime experience and a postwar institution.

  2. Separate founding intention from performance

    The founders' aim is evidence about why they created an institution. It does not prove that the institution prevented every conflict or that all later outcomes arose from the same cause. Evaluating effectiveness requires a different question and evidence about particular decisions and events.

  3. Use the same discipline with a border or alliance

    Record the arrangement you want to explain, the relevant agreement and what changed afterward. Ask whose choices and experiences your account omits. Avoid assuming that every disputed border was drawn in 1919 or 1945, or that later decisions were inevitable.

Before the course is built

Setup asks about your situation first.

Lesson 1 opens on the moment you describe, and the examples use your role. For this request, expect questions like these.

  1. How much do you already know: the outline, the details, or almost nothing?
  2. Are you more interested in the events, the causes, or the consequences for now?
  3. Is there a present-day situation you want to understand through this?

Right for now

If any of this sounds familiar, start here.

You know the dates and not the meaning

Names and years, disconnected from now.

The present references a past you never learned

Alliances, borders and grievances that assume the history.

You want the long view

Why the world is arranged as it is.

Course arc

Where the course goes, in order.

Cadence writes the lessons for you, so the exact path follows your answers. This is the ground a course built from this sentence covers.

01 / 06

The world before

Empires, alliances and the assumptions of 1914.

The First World War

How it started, what it did, and the settlement that followed.

Between the wars

Depression, extremism and the failure of the peace.

The Second World War

Its course, its scale and the moral catastrophe at its center.

The world after

The UN, the Cold War, decolonization and the borders drawn.

The legacy now

Institutions, alliances and grievances that still shape events.

What changes

What you will be able to do, and what you will stop believing.

You will be able to

Understand causes and course

Follow how each war began and unfolded, without memorizing battles.

Trace the consequences

Connect borders, institutions and alliances to their wartime origins.

Read the present

Recognize the wars' legacy in current events.

Ideas this course corrects

The second war was an inevitable replay of the first

Connections between the wars matter, but later choices and conditions still need explanation.

A postwar institution tells us everything about its present role

Founding documents, later changes and current actions are separate evidence. Follow the intervening history.

Course questions

What to know before you start.

How the world wars shaped the world we live in: what can I do today?

Follow a documented institutional link. The UN's history records the drafting and signing of its Charter in San Francisco in 1945 and the organization's official beginning on 24 October 1945 after ratification. Its stated purpose included preventing another world war. This gives a specific connection between wartime experience and a postwar institution. Separate founding intention from performance. The founders' aim is evidence about why they created an institution. It does not prove that the institution prevented every conflict or that all later outcomes arose from the same cause. Evaluating effectiveness requires a different question and evidence about particular decisions and events. Use the same discipline with a border or alliance. Record the arrangement you want to explain, the relevant agreement and what changed afterward. Ask whose choices and experiences your account omits. Avoid assuming that every disputed border was drawn in 1919 or 1945, or that later decisions were inevitable.

Is this a fixed course?

No. Cadence builds the course when you type the sentence and answer a few setup questions, so the lessons follow your situation. This page describes what a course built from this request covers. You see the whole path before Lesson 1.

Who is this course for?

Trace a specific legacy through dated decisions and institutions, then distinguish the original purpose from later results. The world wars changed many arrangements, but a present-day border or conflict can also have earlier roots and later causes. One date cannot explain the whole present. It sits under History & culture in the Ideas & discovery part of the library.

Do I need any prior experience?

No. Setup asks what you already know and where you want to use it, and the course starts from there. Bring a real situation if you have one; the examples are built around it.

How long does it take?

Most courses run 7 to 30 lessons. The course length is sized to what you asked for. You set the pace: one lesson at a time, as often as you like. Lessons can be read or played as audio.

Does this course award a certificate or degree?

No. Cadence is for practical self-learning and does not award accredited degrees or professional certification.
