Before julius caesar was killed, many senators were afraid that he was planning to turn the roman republic into an empire. what caused them to believe this was possible?  

Caesar had been declared a dictator for life.

Explanation:

Julius Caesar was a strong and admired leader of the Roman Republic. Still, many feared he was turning the republic into an empire. He led his army across the Rubicon River to attack his enemies in 49 BC/BCE. This was in spite of the senate ordering him not to do so. Caesar was appointed "dictator for life" in 44 BC/BCE even though Roman dictators were meant to be temporary. He was killed shortly afterward.

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
