Please elaborate on Federalism vs Confederalism.

Federalism is a concept applicable to a county or a
nation, while confederalism refers to the practice of cooperation and collaboration
between countries.

Federal system refers to a system of
government in a country in which the power of government are divided between a central
government and several regional government. The United States of America, and India, for
example, are countries run by federal system of
government.

The opposite of federal system may be called a
unitary system of government in which all power is vested in a central government.
Regional government machinery derives all its powers by delegation from the central
government.

In a true federal system powers in some matters
are reserved for the regional or state governments, while power in other matters the
central government has power over the people of all the country. The respective powers
of the state and the central governments are decided by the constitution of the country,
and neither the central nor state governments have the authority to unilaterally change
such division of powers.

As opposed to this feature of
federalism, a confederation can only act through its individual member states. The
confederation has no authority to directly control of action of people in different
member countries. It can do so only through government of individual member states or
countries.
