The Rubik's cube was invented in 1974 by the Hungarian professor of architecture Ernö Rubik. Some people may remember of it as the Magic Cube since at the beginning its inventor named it "Büvös Kocka", the Hungarian name for Magic Cube.
The Hungarian cube was firstly a success in its native country, and then it became a real triumph in the whole world. The object had been conceived at first in order to develop the faculties of visualization of the pupils in architecture. It turned out afterward that the educational dimension of the Rubik's Cube was much important... It is indeed a natural and material representation of some mathematical principles.

In fact Ernö Rubik had the first idea in spring 1974. He does several attempts and solve the cube for the first time summer (it took him one month to solve it). The final technical solution is ready at the end of the autumn of the same year.
At the beginning of year 1975, Ernö Rubik starts up the necessary process to apply for a patent and starts searching a partner for the industrial production, which finally begins in 1977. The cube quickly becomes very popular in Hungary.

The international interest in the cube began in 1980 to last until about 1983. During this period, a great number of Rubik's Cube was sold.
There were many broadcasts with speed competitions and shows around the cube. There was even a cartoon which dedicated to it. Many clubs were also created almost anywhere.
