This work starts with a small biography of the author, and reports the “happenings occurred in the property Maganja d’aquém Chire”, referring the incidents before the attack to the seat of the Opium Culture and Trade Company in Mozambique in Mopeia, on august 11^th 1884. It describes the conflicts that occurred in Zambezia at the time, a time of the installation of the first truly capitalist company. The abolition of slavery and the settlement of new production model “claimed the destruction of a social order established in the land and assumed by mentalities over the centuries.” The so-called rebellion of Massingire, in 1884, is demonstrative of the conflicts that arose in the crisis generated by the transition from the old regime to the new one in Mozambique, that is, from a “feudal” system to plantation capitalism, which meant loss of privileges to the land owners. In this sense, we are reported facts that are closer to conflicts of class than of nationalist matter. Caldas Xavier, in spite of his partiality, presents a detailed description of the quarrels among institutions and the individuals who represented them in that context.
