India
India is a federal union comprising 29 states and 7 union territories. All states, as well in addition to the union territories of Puducherry and the National Capital Territory of Delhi, have elected legislatures and governments following on the Westminster system of governance. The remaining five union territories are directly ruled by the centre through appointed administrators. In 1956, under the States Reorganisation Act, states were reorganised on a linguistic basis. Since then, their structure has remained largely unchanged. Each state or union territory is further divided into administrative districts. The districts are further divided into tehsils and ultimately into villages.
States Reorganisation Act, 1956
The States Reorganisation Commission submitted a report on September 30, 1955, with recommendations for the reorganisation of India's states, which was then debated by the Indian parliament. Subsequently, bills were passed to make changes to the constitution and to administer the reorganisation of the states.
The States Reorganisation Act was enacted on 31 August 1956. Before it came into effect on 1 November, an important amendment was made to the Constitution of India. Under the Seventh Amendment, the existing distinction among Part A, Part B, Part C, and Part D states was abolished. The distinction between Part A and Part B states was removed, becoming known simply as "states". A new type of entity, the Union Territory, replaced the classification as a Part C or Part D state.
