The horizontal distribution of power-sharing takes place among three branches of government - the legislature, executive, and judiciary. This system of power-sharing is also known as the separation of powers.

1. The Legislature:
The legislature is responsible for making laws. It consists of elected representatives who are chosen by the people. In a democratic system, the legislature represents the will of the people and acts as a check on the power of the executive. It debates and passes laws, scrutinizes the actions of the executive, and has the power to remove the executive through votes of no confidence. This ensures that power is not concentrated in the hands of a single individual or group.

2. The Executive:
The executive branch is responsible for implementing and enforcing laws. It consists of the President or Prime Minister and their cabinet. The executive has the power to take decisions, formulate policies, and implement laws passed by the legislature. However, its actions are subject to scrutiny by the legislature and judiciary to prevent any abuse of power. The executive is accountable to the legislature and can be held responsible for its actions.

3. The Judiciary:
The judiciary is responsible for interpreting and applying laws. It consists of judges who are independent of the executive and legislature. The judiciary ensures that laws are implemented fairly and impartially. It has the power to strike down laws that are unconstitutional and protect the rights of individuals. By acting as a check on the other branches, the judiciary ensures that power is not concentrated and that the rule of law is upheld.

The horizontal distribution of power among the legislature, executive, and judiciary ensures a system of checks and balances. Each branch has its own specific roles and powers, and they can check and balance the actions of the other branches. This helps prevent the misuse of power, promotes accountability, and safeguards the rights and freedoms of the citizens.
