When the news of the revolution in Vienna reached them on the 15th, Petőfi and his friends decided to change the date of the "National Assembly" (a rally where a petition to the Hungarian noblemen's assembly would be approved by the people), from 19 March to the 15th. On the morning of the 15th, Petőfi and the revolutionaries began to march around the city of Pest, reading his poem and the "12 Points" to the growing crowd, which attracted thousands. Visiting printers, they declared an end to censorship and printed the poem and "12 Points".
