All the following are the conditions for the adoption of federalism except

Federalism is a system of government where power is shared between the central government and the constituent units. The conditions for the adoption of federalism include size, population, and defence. However, homogeneity is not a condition for the adoption of federalism. Homogeneity means having a similar or uniform composition. In the context of federalism, a diverse composition of the constituent units is actually necessary for the adoption of federalism. If the constituent units are homogeneous, it may be easier and more efficient to have a unitary system of government. Therefore, the correct answer is "homogeneity."
