Europa Universalis IV (also known as EU4 or EUIV) is the fourth main Europa Universalis game. It was developed by Paradox Development Studio and published by Paradox Interactive. The game was released on August 13, 2013. The game's default is in 1444, the Late Middle Ages, and it continues into 1821, the beginning of the Industrial Revolution. The default start is know as the Rise of the Ottomans, because it is around this time when the Ottomans begin to rise to glory. This is also when the once great Byzantine Empire finally crumbles after the fall of Constantinople in 1453.
