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 centre.

The world after

The UN, the Cold War, decolonisation 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 memorising battles.

Trace the consequences

Connect borders, institutions and alliances to their wartime origins.

Read the present

Recognise the wars' legacy in current events.

Ideas this course corrects

The wars were separate events

Many historians treat them as one conflict with a twenty-year pause. The second grew from the settlement of the first.

The winners drew a fair map

The maps drawn after both wars caused conflicts that continue. Fairness was rarely the priority.

Course questions

What to know before you start.
