# Hearts of Iron 4: World War II Simulation | Economic, Military and Political Management
> Hearts of Iron IV (2016, Paradox): WWII grand strategy — lead any nation from 1936 to 1945: economy, army, politics, national focus trees, divisions and mods. 5 min read.
[Hearts of Iron IV](https://after-strategy.com/en/jeux/hearts-of-iron-4/) is a grand strategy game developed by Paradox Interactive, released on June 6, 2016. Heir to a cult saga, it is devoted to simulating World War II over the 1936-1945 period. As often with Paradox, most nations are playable, from the great powers to secondary countries.
You take control of a nation and manage the country's economic, military and political aspects. Each nation has its own national focus tree, which gives access to varied advantages and lets you choose your place in the coming conflict. For example, you can decide to trigger a communist coup in France in 1936 and completely change the course of the war, or try to save Poland from the German invasion.
## Building Your War Machine
The heart of the game lies in preparing for conflict. You must design your division templates, organize your industrial production, manage your supply lines and train your officers. Battles are fought on a tactical map where terrain, morale and weather matter as much as numbers. A poorly prepared invasion quickly turns into disaster, while a well-executed breakthrough can turn the tide of the front.
## Rewriting History
One of Hearts of Iron IV's great attractions is the immense quantity of mods available. The community is very active and Paradox developers have set up many tools to help modders: total conversions like Kaiserreich or Old World Blues, alternate scenarios, new nations and technologies. Enough to replay World War II dozens of times without ever getting bored. The game also benefits from constant support, with major expansions regularly reworking production, naval combat or diplomacy mechanics.
The division designer is where much of the depth hides: mixing battalions, support companies and equipment lets you tailor armies to the terrain, from cheap infantry for holding rivers to armored spearheads for breakthroughs.
