Kazakhstan country profile
A huge country the size of Western Europe, Kazakhstan has vast mineral resources and enormous economic potential.
The varied landscape stretches from the mountainous, heavily populated regions of the east to the sparsely populated, energy-rich lowlands in the west, and from the industrialised north, with its Siberian climate and terrain, through the arid, empty steppes of the centre, to the fertile south.
Ethnically the former Soviet republic is as diverse, with the Kazakhs making up nearly two thirds of the population, ethnic Russians just under a quarter, and smaller minorities the rest. Suppressed under Soviet rule, the main religion, Islam, is undergoing a revival.
Since independence following the collapse of the Soviet Union in 1991, major investment in the oil sector has brought rapid economic growth, and eased some of the start disparities in wealth of the 1990s.
President: Kassym-Jomart Tokayev
A long-standing colleague of independent Kazakhstan's founder, Nursultan Nazarbayev, Kassym-Jomart Tokayev took over as president when his mentor suddenly stepped down in March 2019.
Mr Tokayev was chairman of the Senate at the time, and says he will continue the policies of his predecessor and rely on his opinion in key policy matters.
He has called snap presidential for 9 June 2019 to consolidate his position.
The new president has served in various senior positions since independence in 1991, including prime minister and foreign minister.
Nursultan Nazarbayev's long authoritarian rule faced few challenges from weak opposition parties, and he managed a gradual transfer of power that guarantees him a future role as chairman for life of a newly-strengthened Security Council.
In addition, his daughter Dariga has succeeded Mr Tokayev as head of the Senate, raising her profile as a potential successor. Presidential elections are due in April 2020.
The media market is dominated by state-owned and pro-government outlets.
TV is the most popular medium. The government operates national networks.
The authorities regularly block websites and access to social media and messaging apps has been cut several times.
