France, Italy, Ottoman Empire, Austria-hungary, and Great Britain.
Explanation:
In the early 1900´s the rising nationalism feeling that France, Italy, the Ottoman Empire, Austria-Hungary and Great Britain started growing and making the tension rise among these nations, this eventually nationalist feeling and the rising tension eventually led up to the starting of WWI with the assasination of the Duke Francis Ferdinand, and all the allies from the different countries involved declared war against eachother because of that rising tension.
In 1900s tensions from growing nationalism divided Europe in 2 groups that fought World War 1. First alliance was between France, Great Britain & Russia. Second alliance was formed between Germany , Italy & Austria. These two groups later fought WW1 .France & Germany were the first ones to face increased tensions because of nationalism.
According to the doctrine of separation of powers, the U.S. Constitution distributed the power of the federal government among these three branches, and built a system of checks and balances to ensure that no one branch could become too powerful.
