Buuxi weedha soo socota: Sannadkii 1809, Upper Peru, Bolivia casriga ah, waxay aragtay abuurista laba junta oo ka jawaabaya xaaladda Spain; jawaab deg deg ah oo ka timid ku xigeennada Lima iyo Buenos Aires ayaa jabiyay kacdoonkii, Upper Peru waxay hoos tagtay gacanta ku haynta Viceroyalty of Peru oo si xoog leh u difaacday. Sanadkii xigay, Buenos Aires lafteeda waxay sameysay xukuumad xukun ah oo meesha ka saartay awoodda ku xigeenka maxalliga ah. Junta, oo uu hoggaaminayay Cornelio Saavedra ayaa ballaariyay si loogu daro xildhibaannada gobollada kale waxayna noqdeen kuwa loo yaqaan "Junta Grande", ama "Junta weyn". Junta Grande waxay amartay laba olole si ay taageero ugu hesho fikradaha kacaanka ee Buenos Aires. Midka ugu horeeya waxa uu ahaa isku day lagu doonayey in lagu qabsado Peru. Guushii ugu horreysay ee Dagaalkii Suipacha waxay keentay dib u dhac iyo guushii boqortooyada ee Dagaalkii Huaqui. Ololaha labaad wuxuu diiradda saaray Asunción ee deriska la ah Paraguay. Buenos Aires waxay u dirtay 1,100 askari oo ka tirsan General Manuel Belgrano Asunción, iyagoo rajeynaya in lagu soo dhaweeyo sidii xoreeyayaal; taa bedelkeed, waxaa looga adkaaday
Paraguay iyo Tacuarí oo ay leeyihiin ciidamada maxalliga ah ee Paraguay. Guddoomiyihii boqortooyada ee Asunción ayaa markaa ka walwalsan daacadnimada raggiisa, wuxuuna ka saaray cutubyada guuleystay. Rabshadaha ayaa sii faafay, bishii Maajo 1811 kacdoon ayaa xukunka ka tuuray gudoomiyihii, iyadoo gooni isu taaga Paraguay lagu dhawaaqay wax yar kadib.
