# How one assassination started World War I

> A process map exported from forks.world (https://forks.world). Author: Brian. Source: https://forks.world/p/cmv21y7nl0016if064dd1jho3
> It describes who does what, in what order, and with which technology. Read the plain-language sections first; the JSON at the end is the exact, complete data.

## Summary

- 12 steps across 1 layer
- Persona: Serbia, Austria-Hungary, Germany, Russia, France and Britain

## How to read this file

- A process is made of **layers**. The main layer is the top level; any step of kind `subprocess` opens a detail layer with its own lanes and steps.
- **Lanes** are either persona (people/roles) or technology (systems). Each step belongs to one lane; `using` lists tools a person uses for that step.
- Step kinds: `start`, `task`, `decision` (its arrows carry the answer as a label), `subprocess`, `end`.

## How one assassination started World War I

Lanes:
- Serbia: person / role (id `serbia`)
- Austria-Hungary: person / role (id `austria`)
- Germany: person / role (id `germany`)
- Russia: person / role (id `russia`)
- France and Britain: person / role (id `france`)

Steps, in the order they run:

1. **A Serbian nationalist kills Archduke Franz Ferdinand in Sarajevo** [start; Serbia; id `w1`]
   - then Blames Serbia and asks Germany for backing
2. **Blames Serbia and asks Germany for backing** [task; Austria-Hungary; id `w2`]
   - then Gives Austria a blank check
3. **Gives Austria a blank check** [task; Germany; id `w3`]
   - then Sends an ultimatum to Serbia
4. **Sends an ultimatum to Serbia** [task; Austria-Hungary; id `w4`]
   - then Accepts most terms but not all
5. **Accepts most terms but not all** [task; Serbia; id `w5`]
   - then Declares war on Serbia
6. **Declares war on Serbia** [task; Austria-Hungary; id `w6`]
   - then Mobilizes its army to defend Serbia
7. **Mobilizes its army to defend Serbia** [task; Russia; id `w7`]
   - then Declares war on Russia and then France
8. **Declares war on Russia and then France** [task; Germany; id `w8`]
   - then Invades Belgium to reach France quickly
9. **Invades Belgium to reach France quickly** [task; Germany; id `w9`]
   - then Britain enters the war over Belgium
10. **Britain enters the war over Belgium** [task; France and Britain; id `w10`]
   - then It is not over by Christmas: the fighting drags on
11. **It is not over by Christmas: the fighting drags on** [task; France and Britain; id `w11`]
   - then Trench warfare grinds on for four years
12. **Trench warfare grinds on for four years** [end; France and Britain; id `w12`]
