His appointment in 1972 as a Secretary of the Party Committee of the native Karaganda Metallurgical Plant was the turning point. In fact, he became the second person after director of the plant on a gigantic scale enterprise in Kazakhstan, where 30,000 people worked.
It was a tremendous responsibility and the severity of which he soon felt fully. He had to deal not only with party affairs, but also production, output programs, issues of maintenance and construction, procurement, household, housing, cultural and family affairs of many people.
He did not hide the shortcomings at the plant and fought with them. As a result, things got better at the plant, rebuilt and refined Temirtau itself.
Nursultan Nazarbayev was working for the wellbeing of people, and was always confident that they will support him. Together with the metallurgists, he climbed to the furnace, together with the miners descended into the tunnel. That is why Nazarbayev without fear entered high offices and seeking justice there also "spoke straight from the shoulder". He was not an unbridled criticaster, always immediately offered reasonable solutions to problems with the arguments urged in his hands. Therefore everybody listen to him carefully and agreed with him. N.Nazarbayev’s authority as a leader was high mainly because he got up from working "lower classes" and was familiar "inside" with all the problems.
At the same time he had a strategic sense, an interest in the future and everything new. There was an enormous need in the country for such experienced and energetic personnel. That is why in 1977 he became Secretary, then the Second Secretary of the Karaganda Regional Party Committee.
In 1979 Nursultan Nazarbayev became Secretary of the Central Committee of Communist Party of Kazakhstan. In 1984 he became Chairman of the Council of Ministers of Kazakh SSR - the youngest, 44-year-old prime minister of the Union republics in the USSR. But despite the relative youth, he was fully mature statesman and politician.
From the height of his new position he was able to fully understand the scope and tragedy of the distortions made in the development of his native country. He sees that Kazakhstan has turned into a huge raw-material appendage of the Union economy.
Sixty percent of consumer goods are imported to Kazakhstan from other republics and the most urgent needs of the people of Kazakhstan were sacrificed in favor of the commodity nature of the development.
He saw that the mind of the other people clears with him and the whole country awakened. December, 1986 became the first Kazakh "spring", which was roughly "frozen" by the Union Center during short years of leadership of G.Kolbin. But it was impossible to stop the time. Ripening changes. Events moved faster and faster.
In the spring of 1989 the first alternative elections to the supreme organ of state power was held in the Soviet Union. In June 1989, Moscow hosted the First Congress of People's Deputies, during which was vigorously debated the need for reform, problems of ideology and economics. Immediately after the Congress of People's Deputies Gennady Kolbin was transferred to work in Moscow. June 22, 1989 the Central Committee of the Communist Party of the Kazakh SSR elects Nursultan Nazarbayev to the post of First Secretary: 154 among 158 participants of the plenum votes in favor.
In July 1989 miners' strike began in Karaganda, where in addition to economic were put forward also political demands - to close the Semipalatinsk nuclear test site. Nazarbayev has actually supported the strikers' demands - he understood people's discontent with the monopoly of the central institutions. He as well as the miners really wanted the economic independence of Kazakhstan and the prohibition of harmful tests.
Democratic processes have led to the creation of mass workers’ unions in the republics of the USSR. One of the first and most popular movements in Kazakhstan was the environmental movement "Nevada - Semipalatinsk", created in the spring of 1989 and had the closing of the Semipalatinsk and the other polygons in Kazakhstan as a final goal. This movement also received strong support of Nursultan Nazarbayev. His efforts with mass support of the people of Kazakhstan achieved unprecedented success - the final closing of the lethal Semipalatinsk test site.
April 24, 1990 the Supreme Council of the Kazakh SSR establishes the post of the President of the Kazakh SSR.
At the session of the Supreme Council of the republic Nursultan Nazarbayev is elected as the first president in the history of Kazakhstan.
December 1, 1991, was held the first national elections of the president of the republic, where Nazarbayev receives the absolute support of his voters.
December 10, 1991 the Supreme Council of the Kazakh SSR adopt a law renaming the Kazakh SSR to the Republic of Kazakhstan and conducts the inauguration of the President of Kazakhstan.
December 16, 1991 the Supreme Council of the Kazakh SSR declared the independence of the republic. Nursultan Nazarbayev becomes the President of the Republic of Kazakhstan.
Then began a new era of independent Kazakhstan.
Grateful nation appreciated the merits of their permanent leader. June 15, 2010 on the basis of the newly established Constitutional Law of the Republic of Kazakhstan status of the Leader of the Nation was assigned to the President of the Republic of Kazakhstan Nursultan Nazarbayev.
