Map of Malaysia

Malaysia is divided into 13 states (Negeri) and 3 federal territories (Wilayah Persekutuan). These are divided between two regions, with 11 states and 2 federal territories on Peninsular Malaysia and the other 2 states and 1 federal territory in East Malaysia. As Malaysia is a federation, the governance of the states is divided between the federal and the state governments, while the Federal government has direct administration of the federal territories.
The 13 states are based on historical Malay Kingdoms, and 9 of the 13 states, known as the Malay states, retain their royal families. The head of state (titled Yang di-Pertuan Agong) is elected by and from amongst the nine rulers to serve a five-year term. Each state has a unicameral legislature known as the State Legislative Assembly. The states of East Malaysia (Sabah and Sarawak) have separate immigration policies and controls and a unique residency status.Visas are required for travel between these two states or between either state and peninsular Malaysia. For some, the other areas of Malaysia are considered foreign countries under immigration laws. Each state is further divided into districts, which are then divided into mukim. In Sabah and Sarawak districts are grouped into "Divisions" ( source :http://en.wikipedia.org/wiki/Malaysia)
