Speaking of Khrushchev, everyone should know that in the early Soviet Union, as a leader, his personality was indeed that people did not know how to communicate, or even how to deal with interpersonal relations, and he was also a bit arbitrary. As for how Brezhnev seized power from Khrushchev, let's take a look at it with the editor!
Khrushchev's new officials took office with three fires, and not long after taking office he could not wait to carry out large-scale reforms, first of all, he laid off the personnel of the government, and a total of twenty-five people left, and Brezhnev was among them. In addition, Khrushchev also carried out other reforms, especially in agriculture, in order to solve the problem of agricultural rigidity, he abolished the lifelong term system of cadres, such reforms were strongly opposed by some vested interests.
Khrushchev arbitrarily carried out a series of reforms, thinking that he could make progress in each of them, but he did not expect that not only did not have good results, but also made a mess in the country. The roof leaked in the overnight rain, and the Cuban Missile Crisis completely lost face in the Soviet Union, and Khrushchev's position became turbulent. Such drastic reforms were already unsatisfactory, and coupled with the poor handling of Khrushchev's interpersonal relations, there were voices against him within Soviet politics.
After Brezhnev left, he went to the Ministry of Defense, and he had close contact with the Soviet army near the water tower, which also paved the way for his later seizure of power. The opportunity soon came, and in 1956, Khrushchev removed Malenkov and others, and Brezhnev seized the opportunity to return to the political core of the Soviet Union again, and eventually became the supreme leader of the Soviet Union. In 1957, a meeting within the CPSU was held during Khrushchev's overseas visit and decided to remove Khrushchev from his post. But this time the resolution was not passed again, and Khrushchev escaped the attack. In 1964, Brezhnev and others made another such resolution, and Khrushchev received a call for an emergency meeting while on vacation in the Black Sea, but he did not expect that this meeting was the meeting that would determine his fate. Brezhnev was well prepared, and nothing more Khrushchev could do. Thus came the end of Khrushchev's time.
To say that the two of them contributed the most to the Soviet Union has always been on the side of Khrushchev, but both have their own contributions and shortcomings. In the hearts of many Soviets, Khrushchev occupies a very important position, although the reforms he made did not achieve very good results, but they also had a certain effect, and many of Brezhnev's actions after coming to power were carried out on the basis of Khrushchev.
During Brezhnev's reign, the focus of reform was on the military and industry, and he continued to develop military strength, defense spending accounted for a large proportion of total national expenditure, the number of nuclear weapons exceeded that of the United States, and the Soviet Union became a veritable military power. Under Brezhnev's rule, the living standards of the Soviet people also improved significantly, and it seemed to be prosperous, but it was precisely because of its vigorous military development that the relations between the United States and the Soviet Union deteriorated for a time, coupled with Brezhnev's blind self-confidence, and finally almost buried the Soviet Union.
The higher he stood, the more miserable he fell, and the position of Khrushchev and Brezhnev in the eyes of the people was also like this, and Khrushchev, because he did not make too outstanding contributions and did not make any irreparable mistakes, whether he was in power or not had little impact on the Soviet people. But Brezhnev was different; during his reign, he made the people realize that life was rich and economically progressive, and finally he made the Soviet Union's economy and diplomacy very bad, and naturally there was a gap in people's minds, so he has always had a very bad reputation.
If I really want to say who contributed the most, I still think that Brezhnev came out on top, although in the end the Soviet Union was killed by him, but at least the Soviet Union was brilliant in his hands, which is undeniable.
