What did the Serbians want, and why did this scare nations like Germany and Austria?

Upon Yugoslavia collapsing in the 1990s with multiple republics seeking secession, Serbian nationalists demanded that all Serbs in all the Yugoslav republics had the right to be united in a common state, ethnic conflict occurred between Serbs seeking unity with Serbia and other Yugoslav ethnicities seeking independence Austria-Hungary's desire to crush Serbia, and Russia's support for the latter during the crisis of 1914, were motivated by fear that they would lose their status as 'Great Powers' if they backed down.This connected Britain, France, and Russia in the 'Triple Entente' and stoked German fears of 'encirclement'.

Explanation:

separation of powers, therefore, refers to the division of government responsibilities into distinct branches to limit any one branch from exercising the core functions of another.   the intent is to prevent the concentration of power and provide for checks and balances.  

the traditional characterizations of the powers of the branches of american government are:

* the legislative branch is responsible for enacting the laws of the state and appropriating the money necessary to operate the government.

* the executive branch is responsible for implementing and administering the public policy enacted and funded by the legislative branch.

* the judicial branch is responsible for interpreting the constitution and laws and applying their interpretations to controversies brought before it.

forty state constitutions specify that government be divided into three branches:   legislative, executive and judicial.   california illustrates this approach; "the powers of state government are legislative, executive, and judicial.   persons charged with the exercise of one power may not exercise either of the others except as permitted by this constitution."

while separation of powers is key to the workings of american government, no democratic system exists with an absolute separation of powers or an absolute lack of separation of powers. governmental powers and responsibilities intentionally overlap; they are too complex and interrelated to be neatly compartmentalized. as a result, there is an inherent measure of competition and conflict
