(a) Marco Polo, the Italian explorer, visited China and learnt the technology of woodblock printing. When he returned to Italy in 1295, he brought this knowledge back with him. Gradually this knowledge spread from Italy to other parts of Europe.

(b) In 1517, Martin Luther, the religious reformer, wrote ninety-five theses that criticised the corrupt practices of the Catholic Church and pasted these on the church door in Wittenberg. Very soon, thousands of copies of Luther’s theses were printed, spreading his ideas among people. Martin Luther was deeply moved by realizing the power of printing, which brought about the reformation movement and the eventual birth of Protestantism.

(c) Print and popular literature encouraged many distinctive interpretations of religious faiths and ideas. In the 16th century, Manocchio, a roller in Italy, began to read books available readily in his locality. He gave a new interpretation of the Bible and formulated a view of God and creation that enraged the Roman Catholic Church. As a result, Manocchio was hauled up twice and ultimately executed when the Roman Catholic Church began its inquisition.

(d) Mahatma Gandhi said these words in 1922 during the Non-cooperation Movement (1920-22). According to him, without the liberty of speech, the liberty of the press and freedom of association, no nation can even survive. If the country was to get free from foreign domination, then these liberties were quite important.
