A revolution in Portugal in 1820 invites the King to return to Europe to accept the Constitution put forward by the revolutionary _junta_ of Lisbon. The monarch leaves his son, Dom Pedro de Alcantara, {182} in Brazil, and quits the country. It is said that on bidding Dom Pedro farewell he cried: "Before long Brazil will separate from Portugal; if it is so, crown yourself before some adventurer gets hold of the sceptre." The Lisbon Parliament wished to destroy the reforms of João VI. in Brazil, and to transform a monarchical nation into a feudal colony, but the Brazilian deputies then in Portugal protested and emigrated to England. A revolution at Pernambuco in 1817 had raised the standard of nationalism. The manifesto or _Preciso_ of the revolutionaries formulated the complaints of the colony. "There is no longer any distinction," said the victorious patriots, "between Brazilians and Europeans; all consider themselves brothers; as descendants of the same origin, as inhabitants of the same country, as believers of the same religion." Journalism, in its infancy, was propagating constitutional ideas both in the north and in the south. Jacobin declamation and romantic ideology created a powerful movement in the taciturn colony. Governmental _juntas_ were appointed in the provinces. Portuguese and Brazilians struggled for political and social domination, but a Lusitanian army, in spite of popular protest, imposed the oath of fidelity to the Constitution which had been promulgated for the metropolis by the distant Cortes. The prince prevented a federal disaggregation and founded the unity of Brazil. He united the representatives of the rebellious provinces, convoked, in 1822, a Constituent Assembly, visited the country districts, and became the "perpetual defender of Brazil." Like the Gothic kings at the time of the Moorish invasion, or the French princes who were faced with feudal anarchy, he founded a national dynasty, and bound the unity and independence of Brazil with the destinies of the monarchy. Dom {183} João VI. had raised Brazil to the rank of a kingdom; Pedro I. rendered it independent of Portugal. "Independence or death!" he cried, in his triumphant Odyssey across the rebellious provinces. At Ipiranga floated the new flag, gold and green, of the new-born Empire. Pedro I. was crowned Constitutional Emperor in December, 1822. José Bonifacio Andrade e Silva, naturalist, philosopher, and soldier, an encyclopædist according to the French tradition, was the minister of this national transformation; he condemned the revolution, having previously supported natural rights and excessive liberties. He suppressed the journals, and the monarch dissolved the Constituent Assembly, whose violence and lyrical propensities were not a help to the political action of a conservative minister.
