Displacement and ocean interconnections: military engineer and journeyman between the Captaincy of Ceará (Brazil) and the kingdom of Portugal

ABSTRACT This article assumes the Captaincy of Ceará (Brazil) connected to an empire in movement. It analyzes the displacement, actions and interventions devised and executed by military engineers and journeymen in transit between the Northern Captaincies and part of the Kingdom. In this sense, it contributes to decolonize the traditional historiography and change the idea of cultural and economic isolation of the captaincy. In the face of the interconnected Portuguese world, the displacement and action of professionals is a possible way of non-island analysis of the conquest and fixation in Ceará's territory. It is important to think about life trajectories. By moving among the most distant places in the Kingdom, connecting distant worlds on transoceanic and territorial routes, they illuminate the global meaning of the colonizing undertaking, spreading and apprehending knowledge, intervening in the territorial and urban space. This study considers both the technical-scientific and empirical knowledge of engineers and journeymen and the transfer, absorption, ruptures of techniques, forms and ideas, expressed in idealizations and hybrid interventions.
