Government reforms are one of those EU4 systems that seems complicated at first but is actually pretty straightforward once you understand it. They’re essentially a tech tree for your government — you earn reform progress over time, and you spend it on reforms that give you permanent bonuses and unlock new mechanics. Here’s how it all works.

The Basics

Every nation in EU4 has a government type — monarchy, republic, theocracy, tribe, and so on. Government reforms are a set of tiers (1 through 12) that you progress through over the course of the game. Each tier has a choice of reforms, and each reform gives you a permanent bonus.

You earn reform progress passively over time. The rate depends on your government type and a few other factors. You can also get reform progress from certain events, ideas, and decisions. Once you have enough progress, you can pick a reform from the next tier.

The Reform Tiers

The tiers are numbered 1 through 12, and they unlock as the game progresses. Higher tiers are locked behind both reform progress and, in some cases, the in-game date. You can’t rush to tier 12 in the first 50 years — the game gates it.

Each tier offers a choice of reforms, and the choices are usually themed around your government type. A monarchy might choose between different types of royal courts, while a republic might choose between different electoral systems. Some reforms are clearly better than others, and some are situational.

Key Reforms to Consider

While the best reform depends on your nation and playstyle, there are a few that stand out across most campaigns:

Tier 1 — The Foundation. This is your first reform, and it’s usually about your government’s core structure. For monarchies, the choice between different court types matters. The Noble Court gives you legitimacy and prestige, which is solid for most campaigns. The Administrative Court gives you cheaper state maintenance, which is great for wide play.

Tier 3 — The Middle Ground. By this point you’re making choices that shape your playstyle. The Parliamentary reforms are strong for tall play, while the Absolutist reforms are better for conquest-focused campaigns.

Tier 5 — The Power Spike. This is where reforms start getting really impactful. The Divine reforms for theocracies are excellent, and the Revolutionary reforms for republics are game-changing.

Tier 7+ — The Late Game. These reforms are powerful but come late. The Imperial reforms for empires are worth planning around, and the Revolutionary reforms can completely transform your nation.

Reform Progress Tips

Getting reform progress faster means getting your reforms sooner. Here’s how to speed it up:

• Pick the right government type. Some governments generate reform progress faster than others. Republics and theocracies generally get more than monarchies.
• Take ideas that boost reform progress. The Administrative idea group has a reform progress bonus, and some national ideas do too.
• Watch for events. Several events give you reform progress as a reward. It’s usually worth taking the reform progress over the alternative.
• Don’t reform too early. This sounds counterintuitive, but some reforms have downsides. Read the tooltip carefully before you pick. A reform that looks good on paper might hurt your playstyle.

The Absolutism Connection

Government reforms interact with absolutism, which is a late-game mechanic that boosts your administrative efficiency. Some reforms give you absolutism bonuses, and having a high reform tier makes it easier to reach high absolutism. If you’re planning a late-game conquest campaign, pay attention to reforms that boost absolutism.

The Bottom Line

Government reforms are a system you’ll interact with throughout the entire game, but you don’t need to stress about them. The key is to understand what each reform does and pick the ones that fit your playstyle. Don’t just pick the first option — read the tooltips, think about your campaign goals, and choose accordingly.

The system rewards planning. If you know you’re going to play a tall trade empire, pick reforms that boost trade and development. If you’re planning a world conquest, pick reforms that boost absolutism and administrative efficiency. The reforms are there to support your strategy, not to dictate it.
