Brazil's border with Bolivia is the longest among other countries, at 3,423 kilometers. This article aims to approach the formation of the northern part of the Brazil-Bolivia border, highlighting the main historical events, materialized in treaties and agreements that left marks in this particular border. The research was structured in four moments: bibliographical surveys about territorial formation; history of the analyzed frontier; field work; construction of maps based on geo-historical information. During Imperial Brazil (1822-1889) the first agreements to establish the limits occurred. In the early 20th century Bolivia and Brazil signed the Treaties of Petropolis and Palmas, resulting in Bolivia's territorial loss, and as part of the agreement Brazil built the Madeira-Mamoré railroad (1907-1912) that allowed Bolivia an exit to the sea. The formation of this particular frontier was the result of a process of state intervention with the advance of settlement and the construction of fortifications for the purpose of territorial control. There was an interest in circulating the production of wild rubber and, to overcome a watery stretch of the Madeira River.
