Montevideo rewards Brazil's vital financial and military support by signing five treaties in 1851 that provide for perpetual alliance between the two countries, confirming Brazil's right to intervene in Uruguay's internal affairs; extradition of runaway slaves and criminals from Uruguay (during the war, both the Blancos and the Colorados had abolished slavery in Uruguay in order to mobilize the former slaves to reinforce their respective military forces); joint navigation on the Rio Uruguay and its tributaries; tax exemption on cattle and salted meat exports (the cattle industry has been devastated by the war); acknowledgment of debt to Brazil for aid against the Blancos; and Brazil's commitment to granting an additional loan.

Borders are also recognized, whereby Uruguay renounces its territorial claims north of the Rio Cuareim (thereby reducing its boundaries to about one hundred and seventy-six thousand kilometers) and recognizes Brazil's exclusive right of navigation in the Laguna Merin and the Rio Yaguaron, the natural border between the countries.
