This article analyses the industrial enterprise of the Dutch-born brothers Abraham and Jakob Momma-Reenstierna and their investments in Sápmi and the upper parts of the Torne River Valley, northern Sweden, during the second half of the seventeenth century. The aim is to explore the driving forces behind the industrial projects of the two brothers in a larger global and colonial context. With inspiration from recent critical studies on the simplifications, and Eurocentrism, in earlier understandings of the birth of modernity, we focus on the modernizing processes taking place in the upper part of the Torne River Valley as a meeting zone between local populations and landscapes and external capital. Metal extraction was booming in the seventeenth-century Sámi areas. Both the Danish-Norwegian and the Swedish Crowns invested heavily in the mining of silver, copper and iron. The scientific focus in archaeology and history has hitherto been very much on the state-governed projects, and limited interest has been directed towards the private enterprises. Moreover, there is also a need to study the roles of the local Finnish and Sámi populations, as well as the global connections, in these colonial industrial projects. ; A Colonial Arena: Landscape, People and Globalization in Inland Northern Sweden in the Early Modern Period
