Quick Overview

The vassalize command in Europa Universalis IV allows a player to turn a specified country (which is identified by its unique tag) into a vassal state.

This means that the chosen nation is now a subject of the player's empire, giving the player influence over its affairs and actions.

In-Depth Description

The vassalize command in Europa Universalis IV (EU4) is a console command that allows you to turn a selected country into your vassal. In EU4, a vassal is a country that is subservient to another, more powerful country (known as the suzerain).

When you enter the vassalize command into the console followed by the three-letter country tag of a nation, that nation immediately becomes your vassal.

Country tags are unique identifiers assigned to each country in the game. For example, to make France your vassal, you would enter vassalize FRA into the console.

This command can be incredibly helpful in situations where you need an ally or a buffer state but lack the means or desire to conquer them outright.

As a vassal, a nation cannot enter into diplomatic relationships or wage wars without the suzerain's approval. That being said, it can also come in handy when trying to manage aggressive expansion, as vassalization does not generate as much as conquering.

How to Open the Command Console

In EU4, cheats are executed from the command console, a text box that you type commands into.

To open the command console press the ~(tilde) key, which is typically located under ESC (escape).

If your keyboard does not have that key, or pressing ~ does not work, try the following keys:

  • ~
  • SHIFT + 2
  • SHIFT + 3
  • ALT + 2 + 1

Type your command into the console, and then press ENTER .
